I build production systems for Web3 products and automation workflows across Farcaster, Base, Arbitrum, and Polygon. Key metrics and proof links are listed below.
I progressed from a single free mint to paid production work across Farcaster, Base, Arbitrum, and Polygon. I build production systems with Node.js and Python, and have delivered 24 production-grade projects with $9,574.17 listed bounty value through bounties, buildathons, and ecosystem programs. Most recently (April 2026), I shipped POIDH Sentinel for bounty #216: an autonomous Farcaster mini app that verifies webhooks, runs minute-level cron jobs, evaluates claims with deterministic checks + OCR + vision AI, and resolves winners on-chain. All bounty metrics on this page are synced to the latest public records from Bountycaster and Farcaster.
