I build scalable distributed systems and full-stack applications with Ruby on Rails, React, and Node.js.

At Cisco Meraki, I architected a cloud-based PCAP solution for network switches, enabling real-time packet analysis for more than 1M devices. I also build full-stack Meraki dashboard features with React and Ruby on Rails.

Previously at Saeloun, I co-developed logistics software supporting 25,000+ weekly meal deliveries and national expansion. I led GraphQL backend and client API development for a customer-facing SPA and reduced production bugs by 60% through end-to-end testing.

At BigBinary and Vineti, I led five engineers delivering cell and gene therapy workflows for Fortune 500 healthcare clients. I built REST APIs and microservices handling 10K+ daily transactions, mentored 15+ engineers, and established code review and TDD practices.

I also built NeetoDesk's mobile ticketing application with React Native and contribute to open-source products including Miru. My technical writing on Rails dual database setup was featured in Ruby Weekly.
