What I'm looking for

I’m looking for a role where I can build scalable SaaS and enterprise systems, own backend and API performance, collaborate closely with product/design in Agile teams, and ship secure features with Rails/React on AWS with strong engineering standards.

I’m a Senior Software Engineer with 5+ years of experience designing and building scalable SaaS applications, enterprise platforms, and customer-facing digital products using Ruby on Rails. I deliver high-quality software for international clients and distributed teams by building resilient backend systems, including high-performance REST and GraphQL APIs and secure multi-tenant architectures.

I optimize complex database queries and improve reliability through caching strategies, background job processing (Sidekiq), and real-time features with Hotwire and ActionCable. I also build responsive frontend experiences with React and Next.js, implement AWS infrastructure with Docker and CI/CD pipelines, and integrate AI-powered features using OpenAI APIs—always with a strong focus on scalability, performance, security, and clean, maintainable code.
