Experience

Senior engineering with product context

I’ve built and modernized software across fintech, payments, trading, healthcare, and enterprise products, working from user-facing interfaces through backend services, databases, partner APIs, and quality systems.

Current independent product

108 Again

Full-Stack Mobile Development & Product UI

I independently designed, built, released, and continue to maintain a production React Native and TypeScript application.

  • Own the product and interface decisions across practice tracking, history, statistics, calendar views, and configuration workflows.
  • Defined the information hierarchy and interaction behavior for responsive phone and tablet layouts, then continued refining the interface from real user feedback.
  • Built the offline-first architecture with SQLite, optional Supabase synchronization, authentication, data portability, automated testing, release processes, and production maintenance.

Toptal

Senior Software Engineer

Selected commercial engagements spanning frontend modernization, healthcare integrations, and real-time trading interfaces.

Life-Assist

Inherited a difficult-to-maintain JavaScript and Knockout.js frontend and migrated major functionality to React. I translated marketing requirements and Adobe XD designs into responsive production interfaces, implemented CSS animations, resolved UI issues, and improved usability, interaction quality, visual presentation, and maintainability. The engagement also included important C#/.NET backend refactoring.
