I am a senior backend and AI systems engineer with more than 15 years of experience building scalable SaaS platforms, distributed systems, and production-grade web applications.
My work focuses on Ruby on Rails, PostgreSQL, APIs, and service-oriented architectures, with a strong emphasis on performance, reliability, and maintainability.
In recent years, I have specialized in AI systems engineering, including RAG systems, MCP servers, AI product integrations, prompt orchestration, semantic search, embeddings, and LLM workflow design.
I have led engineering efforts across healthcare, eCommerce, media, and international SaaS products, delivering MVPs quickly, modernizing legacy systems, and improving operational efficiency.
I enjoy building practical AI-enabled tools that solve real business problems, especially where automation, search, retrieval, and decision support can create measurable impact.
I am open to global remote opportunities and prefer working with teams that value technical depth, product thinking, and high-quality engineering execution.
Architected and delivered backend systems for international SaaS clients. Designed and deployed production-grade RAG systems, built MCP servers, implemented AI product integrations, and created harness and loop engineering workflows for production AI systems. Built and scaled Ruby on Rails applications, improved SQL performance, and maintained high-availability infrastructure.
First engineering hire and delivered the MVP in two weeks. Led a backend team of five engineers, built healthcare APIs for enterprise and government integrations, migrated a monolith toward service-oriented architecture, and improved test coverage and production quality.
Architected eCommerce Rails platforms and optimized Sidekiq workloads, significantly reducing queue backlog and improving system throughput.
Worked on high-traffic backend systems and improved bug turnaround through test-driven development and CI practices.
Built Java and PHP web applications.
Worked on C++ and Java telecom systems.
