What I'm looking for

I’m looking to build secure, high-performance microservices and modern UIs end-to-end—leading CI/CD on cloud, embedding security/observability, and using AI to ship high-quality features faster.

I’m a Senior Full Stack Software Engineer with 7 years delivering secure, high-performance systems for fintech, SaaS, and telecom. I blend Java/Kotlin microservices with modern JavaScript front ends, staying focused on reliability, performance, and maintainable SDLC.

I’ve architected Spring Boot microservices and built React/TypeScript UIs, embedding security and observability from day one. At Collabera, I reduced cross-stack integration latency by 32%, expanded API authorization coverage to 100% for sensitive routes, and improved SEO/load performance by 40%—while automating zero-downtime CI/CD across 12 services.

I also bring AI-driven productivity without sacrificing quality, using GitHub Copilot and Cursor alongside RAG tooling (LlamaIndex/LangChain) to accelerate delivery and improve outcomes. From mentoring a team of 6 to coordinating SOC2-ready assessments and incident response drills, I help teams ship faster with strong engineering fundamentals.
