SUMMARY
Backend-focused Software Engineer with 5+ years of experience building scalable, reliable services and APIs on
Node.js for high-load production systems. Comfortable owning services end-to-end - from architecture and data
modeling to reliability, observability, and production support. I value clean code, thoughtful design, and
shipping features that meaningfully improve the user experience.
Let’s build meaningful solutions together.
