What I'm looking for

I’m looking for a remote-first, async team where I can own architecture end-to-end across frontend, backend, and Web3 integrations—shipping production systems with clear autonomy and engineering accountability.

I’m an independent full-stack developer with 5+ years of production experience across web, mobile, and backend systems. I deliver projects end-to-end—owning architecture through deployment—especially where Web3 integrations, real-time data, and product reliability matter.

Most recently, I’ve been building and maintaining backend infrastructure for a Web3 analytics platform across multiple blockchain networks. I’ve implemented DEX protocol integrations and decentralized exchange adapters, working fully remote and async while self-managing technical decisions from start to finish.

Earlier, I served as a sole developer for a full-stack PWA that used evolutionary algorithms to generate personalized financial investment advice. I independently owned the React frontend, Node/Express backend, and production deployment, from concept through launch.

I’m also proud of customer-validated outcomes—like a Telegram notification service that grew to 7,000+ users organically with zero marketing spend. Whether I’m building internal full-stack apps still used daily or shipping Android and React Native products, I thrive in remote-first, async environments where ownership and clarity drive results.
