What I'm looking for

I seek a role owning full-stack or backend systems at a company valuing scalable, secure architectures, technical leadership, and CI/CD-driven delivery.

I am a Senior Ruby on Rails Full-Stack Developer with over 11 years building high-performance web applications, focusing on API-first architectures, cloud-native deployments, and modern JavaScript frameworks.

I have designed and optimized backend systems using Rails, PostgreSQL, Redis, Sidekiq, and AWS, implemented REST and GraphQL APIs with secure auth (JWT, OAuth2), and introduced CI/CD and containerized deployments to improve reliability and release velocity.

I take end-to-end ownership of platforms, lead technical reviews and best practices, and deliver secure, scalable solutions that balance maintainability and performance.
