Software Engineer · AI Systems Builder · Founder

I build software that keeps working after I walk away from the keyboard. Founder of Lineup, a production booking SaaS, and SolArena, an on-chain prediction market still in progress. Trinity is the local growth engine I built to find and research leads for Lineup, not a separate startup.

Interactive 3D portfolio operating system. Every project below carries an honesty label so you know how real it is.

  • Lineup Booking Platform Production trace

    Founded and built end to end: subscription booking for barbershops with a real multi-constraint availability engine, separate payment states, and five queryable lifecycle stages.

    Stages: SHOP HANDLE · AVAILABILITY · APPOINTMENT · PAYMENT · LIFECYCLE

    Next.js · TanStack Start · Supabase · Stripe · Twilio

  • Trinity Growth Engine Production trace

    Founder-built local-first AI growth engine for Lineup. Evidence ledger before draft, on-device Ollama and Mistral, human OPERATOR checkpoint, correlation ID closed into booking.

    Stages: ALADDIN · SIREN · BROWSER RESEARCH · GENESIS · OPERATOR

    Python · SQLite · Ollama · Playwright · Mistral

  • Evidence Provenance Lab Working demo

    A claim-to-source interface built to do one thing: make AI-generated reasoning inspectable, so you never have to just trust a confident paragraph.

    Stages: SOURCE · CLAIM · REVIEW · RESULT

    SQLite · evidence · review · provenance

    Source

  • Token Tarpit Quarantine Safe simulation

    A bounded security simulation built on the same pacing, challenge, and operator-pause logic that keeps Trinity from running wild.

    Stages: DETECT · SLOW · PAUSE · CLOSE

    state machine · rate limits · operator gates

  • FloodSpy Production trace

    A flood intelligence system that turns sensor data, historical patterns, and community reports into a map you can actually act on.

    Stages: SENSOR · RISK · ALERT

    Next.js · Mapbox · D3 · PostGIS · alerts

    Source

  • SolArena Working demo

    A parimutuel prediction market on Solana, in progress: four Anchor contracts, PDA vaults, 2% fee, oracle vs arbiter locked modes, Phantom signing.

    Stages: OPEN · STAKE · RESOLVE

    Rust · Anchor · Solana · Next.js · Supabase

    Source

  • NeuralNFT Working demo

    An AI-assisted NFT marketplace that connects generated artwork to a real wallet and contract-shaped backend, not just a gallery of pretty pictures.

    Stages: CREATE · MINT · SHOW

    React · Vite · Hardhat · EVM · wallet

    Source

  • Shayo Culture Vibes Working demo

    A commerce experience built to work on narrow screens first, where product storytelling, motion, and cart behavior all move together.

    Stages: STORY · CART · ROUTE

    React · TypeScript · Vite · Tailwind · cart UX

    Source

  • D-Frames Working demo

    An operations surface where orders, employee roles, fulfillment history, and delivery tracking all live in one place instead of five spreadsheets.

    Stages: ORDER · ROLE · DELIVER

    React · Supabase · RLS · orders · delivery

Systems research (blueprints)

  • Neuromancer OS Blueprint — An air-gapped local inference vault, the natural next step from Trinity's Ollama-first way of doing things.
  • Phantom Schema Proxy Blueprint — A conceptual boundary layer that seals real operational data away and hands untrusted requests safe, synthetic records instead.
  • Git-Blame City Production trace — A procedural city built entirely from real commit history, mine, across the portfolio, Trinity, and Lineup repositories.
  • Zero-Knowledge Scheduling Blueprint — A future privacy-preserving handshake for scheduling, designed on top of Lineup's real availability and appointment model.
  • BPE Shatter Lab Working demo — An educational tokenizer chamber that pulls back the curtain on how evidence and prompts actually become model input.
  • FSM Logit Mask Blueprint — A state-machine view of the gap between checking AI output after the fact and constraining generation before it ever happens.
  • Lattice Handshake Blueprint — A future cryptographic exchange, mapped directly onto the real auth, webhook, and funnel-token boundaries already in the system.
  • Evidence Library Working demo — A spatial archive for sources, passages, edits, and outcomes, built on one rule: a confident claim is never treated as proof on its own.
  • Genesis Loss Landscape Blueprint — A visual model of how real Lineup outcomes could eventually teach Trinity which strategies actually deserve a second shot.
