I build and run production systems end to end — schema and migrations, auth and access control, payments, CI, deployment. I like the parts most people hand off: the migration that has to be idempotent across three live databases, the 401/403 test that has to fail loudly, the ledger that has to reconcile.

I use AI coding agents as a core part of the workflow — with review gates, tests and postmortems around them, so the guardrails apply to agents and humans alike.

SieveWorks — a verifiable distributed compute marketplace. A funder escrows a budget on Solana; contributors run search chunks in-browser via WASM, through a CLI, or from a Tauri desktop app, and get paid per verified chunk with finds attributed on-chain.

The interesting problem is trusting work you didn't do. A layered anti-cheat protocol — extremum-witness answers, Merkle commit-and-challenge, secret honeypot seeds, burn-on-slash bonds — targets ~1% verifier recompute instead of full replication. Worker/verifier drift is eliminated by construction: content-addressed WASM hash-verified before instantiation, fixed-point C kernels compiled to native and WASM from one source, and a wgpu/WGSL GPU kernel gated by a bit-exact self-conformance check.

RouteHub @ GeoSafety — the field-operations platform I've led for a year. Three teams on isolated Postgres instances from one codebase, with a versioned migration pipeline that applies stage-first across all three via the Supabase Management API and keeps a per-instance applied-migrations ledger.

~70% of 700+ commits · 150+ migrations in production · 483 RLS policies · 1,200+ tests gated by CI · 88 endpoints

Inside it: a Monday.com-style board engine at 31k LOC (21 column types, virtualized rendering, undo/redo, live presence), a JSONB-configurable PL/pgSQL automation engine, Bank of Georgia payments integration with SQL-side attribution, and GPS-verified site check-ins.

Mercato — an AI agent with its own Solana wallet that evaluates surge-priced API offers and pays for them with x402-style micropayments inside a bounded budget. Took 3rd place and the People's Favorite vote at a 3-hour hackathon, then rebuilt solo at the Solana Startup Village.

_{The card above is generated, not pasted. scripts/generate.mjs renders it as one self-contained animated SVG — no badge service, no stats API, nothing that breaks when someone else's free tier expires — and a GitHub Action rebuilds it daily. GitHub strips scripts from READMEs but runs SMIL inside an <img>, so all the motion lives in the SVG itself. The portrait is an ASCII render of a photo, decoded through ffmpeg with the studio backdrop removed by a flood fill from the border. See scripts/.}
