What I'm looking for

I’m looking to build secure, scalable blockchain and fintech products where I can own the full lifecycle—frontend, backend, smart contracts, and deployment—working in an agile team with strong engineering quality, automation, and security.

I’m a Full-Stack Software Engineer with 7 years of production experience architecting and deploying scalable blockchain and fintech applications. I own end-to-end delivery—frontend, backend, smart contracts, and deployment—bringing modern web quality to high-concurrency decentralized systems.

Over my recent roles, I’ve architected and deployed 40+ production-ready blockchain applications, including DeFi claims, staking mechanisms, and NFT platforms. I’ve built high-performance React and TypeScript interfaces for seamless experiences during high-traffic releases, while engineering secure smart contract infrastructure and backend services that can handle intense blockchain transaction loads.

I also bring a strong engineering discipline: automated testing, code review practices, and production stability focus across multiple projects. Previously, I refactored enterprise microservices and SQL schemas to improve query performance for financial dashboards, and I designed real-time indexing pipelines and RPC layers to synchronize blockchain events with web3 frontends.
