What I'm looking for

I seek senior engineering roles where I can lead architecture for payments or blockchain platforms, mentor teams, and drive scalable, secure systems in a collaborative, growth-minded company.

I am a Senior Staff Software Engineer with 15+ years building high-performance blockchain, fintech, and distributed systems that scale to billions of transactions. I design and deliver end-to-end solutions combining Rust, Go, Node.js, Python, and React with cloud-native infrastructure.

My work includes architecting Payments APIs, ledger services, and reconciliation engines that improved throughput, reduced latency, and cut operational costs while integrating ML for accuracy and automation. I have led migrations to microservices, established CI/CD and observability practices, and driven Rust/Go adoption for performance-critical services.

I mentor engineers across seniority levels, shape engineering strategy, and embed security, cryptography, and best practices into production systems. I thrive in high-growth, cross-functional teams where technical leadership directly improves product reliability and business outcomes.
