I’m a senior full-stack engineer delivering HIPAA-aware SaaS with React Native, React, Node.js, GraphQL.
What I'm looking for
I’m a senior full-stack engineer with 10+ years building production SaaS end-to-end, treating architecture and product decisions as business decisions. I’ve owned entire product surfaces from architecture through App Store/Play Store release, mentoring teams and collaborating closely with product and design in remote, agile environments.
My work spans healthcare, fitness, higher education safety, and logistics—often in regulated environments with HIPAA-aware requirements and Title IX compliance. I specialize in React Native and Expo for mobile, React and Next.js for web, and Node.js with GraphQL for APIs, including type-safe data contracts and compliance-critical onboarding/consent workflows; for example, I boosted internal developer productivity by ~35% by creating reusable component systems.
