What I'm looking for

I seek senior engineering roles where I can architect scalable systems, improve observability and CI/CD, mentor teams, and deliver measurable product impact.

I am a senior software engineer with 9+ years building backend, frontend, and cloud systems using Java, Ruby, Python, Go, React, GraphQL, and TypeScript. I have led end-to-end feature development, re-architected services to reduce technical debt, and delivered AI-driven search and personalization at scale.

I've improved performance and observability across global platforms, built CI/CD pipelines and scalable infrastructure on AWS and GCP, and mentored teams to adopt TypeScript and modern frontend tooling. My work emphasizes reliability, performance, and measurable business outcomes.
