Automation & Backend Developer | APIs, Data Pipelines, Web3 Integrations

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 started with a single free mint and kept building until it turned into paid production work across Farcaster, Base, Arbitrum, and Polygon. I build backend systems with Node.js and TypeScript, with a focus on APIs, automation, data pipelines, and Web3 integrations. So far, I have delivered 3 public projects with $582.15 in listed bounty value through bounties, buildathons, and ecosystem programs. Most recently, I shipped POIDH Sentinel for bounty #216, a Farcaster mini app that verifies webhooks, runs scheduled jobs, checks claims with deterministic logic plus OCR / vision AI, and resolves winners on-chain.
