What I'm looking for

I’m looking to build product-grade, composable systems end to end—owning UX, state, and backend integration. I thrive in teams that value abstraction, accessibility, and shipping fast without sacrificing maintainability.

I’m a Full-Stack / Product Engineer with 2+ years of experience architecting scalable UI systems and shipping products end to end. I focus on composability, abstraction, and system-level thinking to deliver features that feel cohesive in real production environments.

I’ve shipped a production platform serving 5,000+ active users with real-time features, building component architecture and state patterns with Next.js, React, TypeScript, Mantine, and RTK Query. I also built secure file uploads with chunking, progress tracking, and validation, and implemented advanced filtering with debounced search and dynamic query building.

I’ve authored open-source libraries and contributed to Vue.js, Cal.com, Mantine, and PrimeReact, with 130+ combined GitHub stars. From contract work for nonprofits to building my own SaaS (200+ active users), I enjoy turning hard product and engineering constraints into maintainable, reusable systems.
