What I'm looking for

I seek senior full‑stack roles designing cloud-native, scalable systems where I can lead architecture, mentor engineers, and improve CI/CD, observability, and application performance in a collaborative team.

I'm a results-driven Senior Full-Stack Developer with over 10 years' experience building scalable, secure Java and Spring-based backends and dynamic SPAs with React and Angular. I architect microservices, implement CI/CD, and have driven measurable improvements such as 99.99% uptime and large reductions in latency and page load times.

I lead cloud migrations and containerized deployments on AWS and Azure, integrate observability with Grafana/Prometheus/ELK, and mentor junior engineers. I focus on delivering business impact—faster checkouts, higher conversions, stronger security—and on following best practices like TDD and automated pipelines.
