What I'm looking for

I seek senior engineering roles in remote-first teams where I can drive scalable SaaS features, improve performance, lead automation and CI/CD, and collaborate cross-functionally for product impact.

I am a Senior Software Engineer with 8+ years building scalable web and SaaS applications, proficient in TypeScript, React, Next.js, Node.js, and Python. I focus on delivering maintainable, efficient solutions that improve performance and user experience.

At Klaviyo I engineered new platform features, refactored large codebases, and architected REST APIs and database solutions that reduced latency and improved data consistency while supporting high-volume traffic. I also automated backend workflows with AI-driven processes and led containerized deployments and CI/CD pipelines to achieve zero-downtime releases.

I thrive in remote-first, cross-functional teams and bring strong experience in optimizing performance, automating workflows, and translating complex UX/UI into responsive interfaces that increase user engagement and product revenue.
