A street-level cyberpunk RPG for the browser where every fight is a puzzle. Both fighters share one 8x8 grid and take turns swapping tiles, so every move also sets up, or denies, the other side's next one.

• Deterministic TypeScript engine: a seed plus the move list replays any fight exactly, which keeps live duels in lockstep.
• Live duels, crews and a city-wide feed over Supabase Realtime; ratings only change on the server, behind row-level security.
• Ranked async PvP against other players' saved builds, played by an AI that looks a move ahead.

Castle against castle, hero against hero. Your army marches on its own while you lead your hero from the walls and aim every shot yourself. Six races, a five-act campaign of 42 stages with bosses, and online 1v1.

• Pure, seeded simulation: online duels run in deterministic lockstep through a small relay (hash checks, resync, rejoin), and replays come out byte-identical.
• Headless AI-vs-AI battles balance the races and tune every act of the campaign in seconds.
• All art and music are procedural, drawn on canvas and scored in WebAudio with no asset files, and it plays on phones with touch controls.

A cyberpunk roguelike deckbuilder: climb a tower of fights, elites, gigs and ripperdocs and reach the moon before your chrome takes over. Every implant costs Humanity, and the less you have left, the stronger and less stable you get.

• Three runners with their own mechanics: Tempo that makes your next card play twice, quickhacks uploaded into enemies, and Heat you build up and vent.
• Deterministic engine: a seed plus your inputs replays any run exactly, so saves resume where you left off and the server can verify leaderboard results.
• Accounts, daily seeded runs, leaderboards and dossiers on Postgres, with cel-shaded characters, procedural card art and fully synthesized audio.

All-in-one practice management platform for law firms across Europe: clients, cases, documents, time tracking, billing and a client portal, in 17 languages.

• Led the User Management module: accounts, roles and permissions that guard sensitive client and case data.
• Built and maintained Matter Management, which ties clients, documents, time entries and billing to each case.
• Developed KYC/AML client checks and Conflict Checking, which flags conflicts of interest before new work is accepted.

AI products for German law firms that grew out of my first RAG and LLM projects at stp.one. Legal Twin reads an entire case file, summarises it and pulls the key people and dates into a single-page view.

• First developer working full time on RAG and LLMs: built a legal assistant that answers questions from uploaded case files and German legal texts.
• Scraped and processed large volumes of public German court decisions, and fine-tuned open-source LLMs on them.
• Integrated Legal Twin into stp.one's established legal and insolvency software.

A personal training app for runs, rides and hikes: record with GPS, analyse every activity, plan routes and follow your fitness. Every feature unlocked, and all data stays on your device.

• GPS recording with live pace, voice splits, Bluetooth heart rate, live segments against your record, and live location sharing by link.
• Analysis with maps coloured by pace or heart rate, 3D terrain, grade adjusted pace, zones, power curve, detected climbs and segment leaderboards.
• Route planning that snaps to roads and trails, a loop generator for a target distance, offline maps, and GPX, TCX and FIT import.

A private food diary: calories and macros, barcode scanning, recipes, water, exercise and weight. It installs on your phone, works offline, and every feature is free.

• Search over 13,000 bundled USDA foods, and scan barcodes with the phone's camera against Open Food Facts.
• AI meal scan: photograph a plate or share an image, and Gemini estimates the foods and grams for you to review and save.
• Local-first in IndexedDB, with optional accounts that sync through an outbox to Supabase behind row-level security.

A keyboard-driven market terminal that runs in the browser: four panels, an amber command line, numbered function menus and live quotes that flash on every tick, across stocks, indices, FX, commodities and crypto.

• 22 functions, from price graphs, fundamentals and options chains to heat maps, the yield curve, news and economic calendars.
• A terminal command grammar of security, market sector and function (AAPL US Equity GP), plus name lookup and numbered menus.
• One serverless proxy feeds every panel: it handles the data source's session handshake, batches quote requests and works around its quirks.
