What I'm looking for

I'm seeking remote roles building scalable web and mobile products with Ruby on Rails and React, on collaborative, agile teams that prioritize user-centered design, measurable performance gains, and opportunities for technical leadership.

I am a results-driven Full Stack Developer with 8+ years building scalable web and mobile applications for clients across the USA, Canada, and Europe. I consistently deliver performance gains—reducing load times up to 50%, boosting engagement by 30%, and completing projects ahead of schedule. I thrive in remote, distributed teams and enjoy collaborating across time zones to translate product goals into reliable, user-focused solutions.

I specialize in Ruby on Rails, React, React Native, Next.js, PostgreSQL, and AWS, with strong experience in API integrations, CI/CD, and TDD. My work includes a 5,000+ musician community platform, a telehealth CRM serving 10,000+ patients, and a medical workflow system integrated with EPIC, all delivering measurable business impact.
