About me
I’m a senior backend and full-stack engineer with 10+ years of experience building reliable web products and APIs. I specialize in Ruby on Rails, GraphQL, PostgreSQL, AWS, Docker and performance-focused backend systems. I also build practical AI integrations using LLM APIs, RAG, structured outputs, tool-calling workflows and guardrails. I can help debug existing Rails applications, design clean APIs, integrate third-party services, improve reliability and introduce AI where it creates measurable value. I communicate clearly, work autonomously and collaborate comfortably with product
