Senior full-stack software engineer delivering scalable web platforms and strong cross-functional leadership.

What I'm looking for

I seek senior engineering roles where I can lead end-to-end product features, improve system scalability and developer experience, mentor teams, and work in collaborative, fast-paced environments.

I am a senior full-stack software engineer with 10 years building scalable web applications across startups and high-growth tech companies.

I design and implement backend microservices and high-performance frontends using modern JavaScript frameworks, Python, Java, Go, and Ruby on Rails, and I optimize systems for performance and reliability.

I have led product features end-to-end, improved frontend load times by 35%, backend performance by 30%, and helped build systems handling millions of daily transactions with strong compliance and observability.

I prioritize developer experience, clean architecture, mentorship, and cross-functional collaboration to deliver secure, production-ready platforms that scale.
