Full-Stack Engineer building secure backend, payments infrastructure, and Web3 systems.
SwitzerlandWhat I'm looking for
I’m a Full-Stack Engineer with 5+ years building production SaaS serving 21K+ users, with deep expertise in secure backend systems, payments infrastructure, and Web3 architectures. I’ve shipped 12+ end-to-end features across frontend, backend, smart contracts, and DevOps—processing 1,000+ monthly transactions across fiat and crypto rails at 99.9% uptime.
In my current role, I architected and shipped core features end-to-end—from merch storefront and creator analytics dashboards to custodial wallets and payment rails—while cutting manual reconciliation effort by ~60%. I engineered ERC-721/erc-1155/ERC-20 smart contracts on Polygon with Chainlink price feeds, hardened JWT-secured APIs with rate limiting, and resolved 20+ critical incidents with average MTTR under 30 minutes. I thrive on production debugging, incident response, and building reliable event-driven systems that scale.
