What I'm looking for

I seek remote-first roles where I can architect secure, scalable full‑stack systems (healthtech/fintech), lead API/cloud initiatives, integrate AI analytics, and collaborate cross-functionally to deliver measurable impact.

I am a Full-Stack Engineer with 7+ years building scalable, secure applications across health tech, fintech, and eCommerce, focused on Ruby on Rails, React/Next.js, and API design.

I have delivered measurable impact: improved patient engagement by 25%, handled $18M+ in payment volume, supported 150K+ healthcare providers, and engineered real-time systems syncing 120K+ health events/day. I architect FHIR-compliant EHR integrations, refactor background workers for reliability, and optimize frontend workflows to reduce support tickets and speed coordinator tasks.

I prioritize maintainability, observability, and cross-functional collaboration—prototyping with Figma and Storybook, automating deploys with Terraform and GitHub Actions, and integrating AI analytics to drive actionable product outcomes.
