Eight years of marketing taught me what to build. So I built it.

21 systems. 19 live, 2 at demo stage. This page is the 22nd.

I'm Leon Szczaurski, based in Fort Lauderdale and founder of Happy Client LLC. I build the systems below, and I run them.

Everything that’s running

Sixty screens below, every one captured from something I built. No mockups, no stock images, nothing generated.

60 captures · 7 builds · 3 slots reserved

19 live, 2 at demo stage, plus this site. The wall above is 60 real screens from 7 builds and 3 reserved slots: the private 2b board, Wardrobe, Design HQ. What is missing runs without a screen or behind auth: CLIs, cron loops, Telegram bots, phone lines, NAS services.

Flagships

Five systems, in depth.

These five carry the most weight, so each one gets a chapter. Every number below was measured on hardware I own, and where there is nothing public to open, the card says so.

01 Platform live

2b, the second brain

Eighteen widgets read and write one Obsidian vault: bank balances through SimpleFIN, call recordings, NAS health, API spend, a phone dialer. The vault is plain Markdown on a disk I own, and that is the whole architecture decision. Files are the truth. Apps are disposable lenses over them. If every app I wrote stopped working tonight, the notes still open in any text editor tomorrow.

  • Runs on the Mac and independently on the NAS
  • The app itself sits behind one password plus a Telegram device code
  • The in-browser terminal fails closed: 403 on an unauthenticated socket, verified

The board header, captured from the live showcase.
02 Infrastructure live

The NAS home brain

A UGREEN NAS over a 7.3 terabyte pool holds the vault, syncs it live to every device, runs a write-capable Claude container, and publishes the public sites through an outbound-only Cloudflare Tunnel. The Mac is only a client. Shut the lid and the Telegram bot still answers, the 07:30 brief still goes out.

  • 18,534 documents syncing live through CouchDB
  • vault-committer commits the vault onto a git bus every 120 seconds
  • Everything is Tailscale-only except the sites the tunnel publishes
Open files.szczleon.com

Mac and iPhone sync into the NAS. The NAS runs the vault-committer git bus and publishes the public sites through the Cloudflare Tunnel.

Reserved: turntable clip of the NAS. Not shot yet.

03 Agents live

The cabinet and the build team

Nine named agents run tool-enabled shifts over the vault on a schedule set by a Markdown note, and an Overseer audits them at 21:30. Beside them, a Windmill flow runs an orchestrator, nine parallel specialists, and a checker. Done is not a model announcing it finished. The checker reopens the spec, tests every acceptance item against the files on disk, and sends the team back around until they pass.

  • Nine specialist roles: frontend, backend, uiux, copywriter, researcher, qa, axseo, editor, animator
  • No deployer role. Going live is always a human step.
  • Nothing to open here: the flow graph lives on the Tailnet
4.17B
tokens through the team, June to July 2026
$412
actual cost of that run, against $5,560 at list API rates

Subscription auth, not metered keys. The gap between those two numbers is the reason a one-person shop can run a build team at all.

04 Voice live

Voices that answer the phone

Two lines are working. Joy is a business front desk that takes and places real calls over a Twilio SIP trunk and answers from that business's own service list and prices. The second line is mine. I talk to my second brain, it writes a row into the vault task queue, a Mac runner executes it, and the receipt lands in Telegram. Anything destructive, outbound, or involving money gets refused on the call.

  • Joy: a Retell voice over a Twilio SIP trunk
  • 2b Voice: $0 standing cost, about $0.07 a minute while talking
See the call scenario run
  1. 00:00 Connect. The call opens on the Twilio SIP trunk.
  2. Ground. Answers come from the real service list and prices.
  3. Book. The slot gets written down.
  4. 13:00 Receipt. Transcript and outcome land in Telegram.

Two real calls placed 2026-08-05. The longer one ran 13 minutes and cost about $2.70. Those are the measured numbers. The stages are the shape of a call, not timestamps.

05 Pipeline live

The deal machine

One person cannot run a sales process on willpower, so the whole line got built: pitch, sign, pay, dial, measure. Every stage runs on my own agency before it goes anywhere near a client.

  1. Pitch

    Pitch Portal live

    Two decks deployed, one of them 23 slides. A buyer panel caught a weights-sum-to-130 bug before a client saw it.

  2. Sign and pay

    Onboarding portal live

    Cart to one link to a signed agreement. Composite mint verified at $10,747, $6,497 deposit, 9 scope lines. Card payments wait on a Stripe recovery.

  3. Dial

    HC Call Machine live

    A power dialer that needs no API keys. 18 recordings transcribed locally through whisper.cpp, speaker labeled.

  4. Measure

    hc-scanner live

    AI visibility and security scoring. happyclient.agency got rebuilt until it passed 100/100, and now every new site has to.

  5. Measure

    ax-monitor demo

    Ten buyer questions, eight repetitions, four AI channels, weekly. Dry-run verified, and it cannot run live until keys exist.

  6. Productize

    Distributor CRM demo

    The house platform rebuilt as a vertical the client owns outright. Demo finished, not sold.

Lab

Eight smaller builds, running in miniature.

The long tail of the workshop. Each stage below is drawn from DOM and CSS rather than a screenshot, so it loads at almost no cost and you can still select the text. Point at a cell to freeze its loop on the frame you are reading.

01

semsearch

Ask in plain language and the exact old conversation comes back, matched at 0.74 similarity with no keyword overlap at all.

Live 2026-08-06. 1,352 files and 23,783 chunks, embedded locally for $0 a query.

02

vcut

Raw talking-head footage goes in and a cut Final Cut project comes out, with every silence over 0.55s removed by arithmetic instead of by the model.

Live Timing is arithmetic, selection is editorial. The model never returns a timecode.

03

Wardrobe

Photograph a garment, let the draft pass fill in its attributes, then check out an outfit and get a render of it worn for $0.08.

Live Phases 1 and 2 verified 2026-08-06. Every garment is a vault note, not a database row.

04

Bonsai

Focused time grows a tree whose foliage is placed by a real light model, on an engine covered by 62 green tests.

Live Phase A shipped the same day it was specced. Neglect it and the tree can die.

05

Deal Scout

A 09:00 sweep of Marketplace, Craigslist and OfferUp comps every find against sold data, haircutting asking medians by 20% before it reports a spread.

Live 2026-08-02. Three keyless sources, no logins risked, and the agent only drafts. I send.

06

image-gen service

One router in front of fal.ai that prices a job from live rates before it runs and refuses to spend past a $25/mo hard cap.

Live Photos and hero art only. Logos are drawn by hand in SVG, never generated.

07

Build recorder

Allowlisted build sessions record themselves to the NAS with a timecoded shot list, and default deny keeps vault, client and money work off the tape.

Live 2026-08-06. A real shot list landed 2026-08-08, for a session on this rebuild.

08

PACT bot

Two people commit to a pact and check in through @pactapp_bot, with the whole challenge tracked inside a Telegram Mini App.

Live Mini App since 2026-06-25. The crypto escrow is built and stays off until a testnet dogfood week is done.

Every one of these runs on hardware I own, and I answer for all of them.

Camera

Content built to sell, not just to look good.

I come from marketing, not film school. Every shot is framed with the ad account and the product page in mind, so the result looks premium and pulls its weight commercially.

Case study delivered

MindBlend mushroom coffee: a full content engine in two shoot days

  • 30 short-form vertical videos (15 to 45s) for Instagram, TikTok, and paid social
  • 60 product and lifestyle stills
  • Concept, shot list, filming, lighting, edit, and delivery: one person, end to end
  • Delivered organized by use case, ready to post

Shot on a Sony A7 IV with a macro and production lens kit, moved on a gimbal, lit with my own production lighting, cut in Final Cut Pro. The product frames were shot on my own product backdrop, so the whole engine ran out of one room and one pair of hands.

Movement, framing, lighting, and detail shots chosen to raise the perceived value of the product.

The shot index

Four rows drive one stage. Two of them are reserved slots: that footage is not cut yet, and I would rather show you an empty frame than someone else's clip.

Reserved slot

Reel in the edit

A 60 to 90 second cut of the MindBlend footage. The footage exists and the stills below came off the same two days. The cut does not exist yet, so this frame stays empty until it does.

03 Stills. Two shoot days, one person, end to end.

Reserved slot

Build sessions, recorded not cut

The Build recorder has been screen-recording my own build sessions since 2026-08-06, and a timecoded shot list landed 2026-08-08 for a session on this site. vcut turns that footage into a Final Cut project. When the first session is cut, it lands here, which makes this page's own footage pipeline the thing that fills this page.

Story

You'd be hiring a marketer. the guy who builds the machine.

8 years of marketing came first. 200 cold calls a day at the start, national retail launches by the end. I did not learn what to build in a bootcamp. I learned it doing the job without the tools I now write.

  1. 2017 to 2019

    Freelance social media multiple clients

    Instagram and Facebook accounts for clients in publishing, wellness, and speaking. They grew faster than their competitors, and I learned that the account posting on a schedule beats the account posting when someone feels like it.

  2. 2020

    Sales and marketing Squid Distribution

    200 calls a day. Client retention went up 88%.

    The list and the follow-up were already a system by then. It just ran on paper, and on me.

  3. 2021 to 2022

    Marketing and business development Fume

    Helped originate and manage a $24M annual distribution agreement, and contributed to the brand's European market entry.

    Fume became the most popular vape brand in Florida. I sponsored III Points and supported a 25-car branded fleet activation.

  4. 2023 to 2024

    Regional marketing manager Earth Kratom

    A $15K monthly budget, six or seven trade shows a year, and promo teams I hired and led.

    A new brand went into 150+ retail stores and 10+ wholesalers across four states in 10 weeks: Georgia, the Carolinas, Alabama. It became the number one picked-up brand in Georgia and Florida.

  5. 2024 to 2025

    Brand development and account management Kats Kratom

    Took a direct-to-consumer brand into brick and mortar: the smoke-shop wholesale channel across South Florida, then expansion into Orlando, Tampa, and Fort Myers.

    I wrote the whole B2B outreach machine by hand, gatekeeper scripts and email sequences and named-account campaigns, then spent most of every week keeping it fed.

  6. 2025

    Marketing advisor Adler Social

    Consulting for small businesses in hospitality, wellness, and retail. Client visibility across Google, social, and the web went up about 77% on average.

    By then I was rebuilding the same handful of spreadsheets for every account, which says more about the spreadsheets than about the accounts.

  7. 2025 to now

    Founder Happy Client LLC

    Premium content, brand growth, and self-hosted AI systems for small businesses.

    The stack I used to rent taught me what a stack has to do. HubSpot, Klaviyo, Mailchimp, Zoho, WooCommerce, all of it billed monthly to do things I could describe exactly. The dialer, the CRM, the site scanner, and the onboarding portal further up this page are the versions I wrote, and they run on hardware I own.

Every system on this page started as a job I was doing by hand.

About

One person, end to end.

Leon Szczaurski directing a MindBlend lifestyle shoot poolside with a gimbal, Fort Lauderdale
On the MindBlend shoot, Fort Lauderdale. Gimbal in hand, not a headshot.

I build and operate AI systems: a self-hosted second brain over plain Markdown, agent teams that run scheduled shifts, voice agents that take real calls, and the tools my own agency runs on. Eight years of marketing came first, from 200 cold calls a day to helping originate a $24M distribution agreement. I’m based in Fort Lauderdale, Florida, and I founded Happy Client LLC. One person, end to end: I design it, build it, host it on hardware I own, and answer for it.

Who I build for

Whether you’re a founder with a product and no content, a business nobody’s AI can find, or an operator buried in your own admin, you get the same one person, start to finish.

Production team and MindBlend founders on set after a content shoot day in Fort Lauderdale

30 videos + 60 stills, 2 shoot days

A founder with a product and no content

MindBlend, a mushroom coffee brand. Concept, shot list, filming, lighting, edit, and delivery, all of it mine, shot on my own kit and cut in Final Cut Pro. Two shoot days, one room, one pair of hands.

delivered

hc-scanner report capture pending Reserved frame for an hc-scanner report: the ranked AI-visibility and security findings the tool prints for a site, with the score at the top. The scanner runs as a command line tool, so no screen capture of a report was on disk when this section was built.

100/100 on my own agency site

A business nobody’s AI can find

I wrote hc-scanner, which scores how visible a site is to AI search and how exposed it is security-wise. Standard library only, no dependencies. I pointed it at my own agency site and rebuilt until it passed, and that pass is now the gate every site I build has to clear.

in use

Six more 2b widget cards: Wins and Achievements with photo capture proof, the Team and Cabinet agent inbox, Calendar, Terminal running Claude Code inside the board, Audiobook and the Water and Vices tracker.

agents that work a shift while I sleep

An operator buried in their own admin

Named agents run scheduled daily shifts over the same vault, driven by a plain Markdown note instead of a config file. The client-facing version of the same idea is a self-hosted CRM the business owns outright rather than renting a seat. That one is at demo stage.

running daily

100/100

AI visibility.

This page is written to be read by machines as well as people: schema on every entity, an llms.txt, open crawlers, and no JavaScript gate in front of the content. Scanned with hc-scanner, the tool I wrote.

Receipts

No testimonials on this page yet. I’d rather hand you things you can open.

Recency

Still shipping.

The fair objection to a one-person shop is that the page might be a museum by the time you read it. Every row below is dated, and each one belongs to a build further up.

  1. The Build recorder wrote a timecoded shot list for a szczleon.com build session, so this page has B-roll of itself being made.

  2. Wardrobe phases 1 and 2 verified: photograph a garment, a headless model drafts its attributes, and the outfit cart renders a try-on.

  3. semsearch went live: ask in plain language and the exact old conversation comes back, indexed locally, no API key and no monthly bill.

  4. The Build recorder itself went live once the screen-recording grant landed. Allowlisted projects only, with vault, client, and credential work blocked from recording.

  5. Bonsai Phase A shipped the same day it was specced: six commits, a tested growth engine, and a tree that can genuinely die.

  6. Joy, the front-desk voice agent, placed two real outbound calls over a Twilio SIP trunk and completed them.

Leon Szczaurski builds and operates AI systems: a self-hosted second brain over plain Markdown, agent teams that run scheduled shifts, voice agents that take real calls, and the tools his own agency runs on. Eight years of marketing came first, from 200 cold calls a day to helping originate a $24M distribution agreement. He is based in Fort Lauderdale, Florida, and is the founder of Happy Client LLC. One person, end to end: he designs it, builds it, hosts it on hardware he owns, and answers for it.
What does Leon Szczaurski build?
He builds and runs the systems himself: a self-hosted second brain over a Markdown vault, a team of AI agents that work scheduled shifts and gate their own completion on evidence, voice agents that place and take real phone calls, a semantic search index over years of his own conversations, and the sales machinery his agency runs on, from the pitch deck engine to e-sign and payments. The oddest one is Prank Line, a comedy AI caller whose premises live as Markdown notes and which always reveals itself before the call ends.
Where is Leon based, and does he work remotely?
He is based in Fort Lauderdale, Florida. He works with South Florida clients in person and takes on remote work as well.
What is Happy Client LLC?
Happy Client LLC is Leon's agency. It delivers self-hosted AI systems, automation, and premium content for small businesses.
What is AI Visibility (AX)?
AI Visibility, or AX, is making a business readable and citable to AI search tools like ChatGPT, Perplexity, and Google's AI. Leon audits and rebuilds a business's structured data, semantic markup, and machine-readable content so it gets found and cited when customers ask. He wrote the scanner that scores it, and he rebuilt his own agency site until it passed at 100 out of 100.
