What I'm looking for

I’m seeking senior backend or full-stack roles where I can architect scalable systems, mentor engineers, and improve reliability and performance.

I’m a Senior Software Engineer with over a decade of experience building scalable, high-performance backend systems, primarily using Ruby on Rails, ActiveRecord, and related technologies. I design and deliver robust APIs, optimize databases, and modernize legacy systems to support reliable production workloads.

At Meta, I led development on Facebook Shops, implemented real-time inventory synchronization, integrated Kafka and AWS SQS for messaging, and optimized CI/CD and monitoring to improve reliability. I consistently drive performance improvements, test coverage, and operational efficiency across services.

I enjoy mentoring engineers, leading design sessions, and applying pragmatic architecture patterns—microservices, event-driven systems, and test-driven development—to solve complex technical challenges and deliver maintainable solutions.
