What I'm looking for

I seek roles where I can lead backend and blockchain engineering efforts, design scalable microservices, work with cross-functional teams, and contribute to high-impact fintech or Web3 products with strong DevOps and growth opportunities.

I am a Senior Software Engineer with 6+ years building scalable enterprise applications, primarily in fintech, payments, and blockchain. I specialize in backend architecture, microservices, cloud infrastructure, and delivering high-availability systems used by millions.

I have led engineering efforts for multi-country payment systems, DeFi platforms, and large-scale election and public-sector solutions, improving performance and reducing costs through smart architecture and DevOps practices. I am a Certified Scrum Master who mentors teams and drives engineering best practices.

I focus on measurable outcomes—system performance, uptime, transaction throughput, and deployment velocity—while staying current with emerging technologies and fostering strong cross-functional collaboration.
