# building from silicon to cloud — embedded firmware, mobile apps, web platforms, self-hosted infrastructure, and AI tooling for pixel art.
$ stack --layers --verbose
Five layers, one person. Most of these projects touch three or more of them at once — the dartboard runs from an ultrasonic sensor to a phone screen, and the server under the desk is the same one serving this page.
$ ssh paisbru && watch -n30 ./status
Everything below runs on one machine under a desk in Alberta — WSL2, Docker, a Cloudflare Tunnel and no open ports. These numbers are read from it every 30 seconds.
19 CONTAINERS
Reverse proxy, four databases, the tunnel, monitoring and every app above — restarted unless-stopped, backed up nightly.
$ cat featured/README.md
The project that explains the rest of them. A dart hits a physical board, ultrasonic sensors on an ESP32 work out where, a Python bridge writes the position to a database, and a React Native app has the score before the dart stops wobbling.

Free bilingual (EN/ES) electronics course where every concept ships with an instrument you operate and a consequence you see or hear at the same instant. Circuits are drawn as live SVG components rather than images, so values update as you turn a knob and the prose can highlight the exact part it is talking about. Twel…
Web app to track filling the Panini World Cup 2026 sticker album (980 stickers): owned / missing / duplicates, special-colour parallels with rarity, and QR swap-codes compatible with the official app's format (reverse-engineered gzip bitfields). Full accounts — email, Google and Microsoft sign-in, two-factor auth — plu…
Turn any Spotify track into guitar tabs and 16-bit chiptunes. Songsterr-first pipeline pulls official human-transcribed tabs, with an ML fallback (Demucs + basic-pitch) for songs it doesn't have. The chiptune engine quantizes the transcription onto a beat grid and rebuilds it as melody / harmony / bass voices — with op…
Self-hosted spending tracker and debt payoff planner for one household. Imports CSV/OFX/QFX bank statements with per-account column mapping and hash-based dedupe (re-importing overlapping statements never duplicates, and every import can be undone), then auto-categorizes with a rules engine plus an optional Claude pass…
Desktop AI sidekick for pixel-art workflows. Electron app with tools backed by Claude (palette gen, sprite critique with vision, tileset planner with autotiling rules, animation brief, concept generator) plus per-project reference libraries and a re-runnable call history. Self-hosted ComfyUI container runs SDXL Turbo +…
A curated local guide to the businesses of Spruce Grove and the tri-region: original photography and written profiles on top of a complete directory, with local deals. API-first — every read goes through a versioned data/meta envelope, so the planned Expo app is a client rather than a rewrite. Postgres full-text search…
16-bit side-scrolling tribute platformer in Godot 4. Each level is a Green Day song with chiptune backing generated live by MakeTabs. Art direction: Scott Pilgrim-inspired pixel art. Game design document complete, asset pipeline being built in Retro Creator.
Tracks Canadian CAD prices on AMD CPUs and GPUs across retailers — Newegg and Canada Computers via axios/cheerio, and Amazon.ca through a Playwright stealth microservice. Full price history in PostgreSQL, interactive charts, GPU AIB variants and a price-alert system, refreshed on a schedule. Presented as a silicon tele…
Custom PCB built around ATmega328p. A VL53L1X laser distance sensor detects proximity, driving an 8-LED strip and a 128×32 OLED display to give visual feedback about computer usage time.
Mobile Pokédex app built with React Native. Fetches Pokémon data from PokéAPI and presents it with a clean browsable interface.
Admin dashboard for managing an e-commerce platform. Allows updating product information through a clean Next.js interface.
Full self-hosted stack on WSL2/Docker running 24/7 behind paisbru.com: nginx, PostgreSQL, MongoDB, MySQL, Redis, a Cloudflare Tunnel with no open host ports, Cloudflare Access on anything private, Uptime Kuma monitoring, Portainer and Adminer. Nineteen containers serving this portfolio, Workbench, MakeTabs, the AMD tra…
$ ./contact.sh --open
Open to opportunities, collaborations, and anything that needs a person who is as comfortable with a soldering iron as with a Dockerfile.
