Xnapper — Product Engineering
I helped evolve a commercial screenshot product into a broader image and video editing experience, owning complex capabilities across interface, state, processing, persistence and production delivery.
View case studyI build full-stack products and complex features end to end.
Full-Stack Software Developer working with TypeScript, React, Next.js and Node.js. I turn product problems into maintainable features across UI, application logic, data and production workflows.
Track record

Featured Work
End-to-end product delivery
Owned end-to-end features for a commercial product with approximately 20,000 users, working across React/Next.js, application state, Node.js processing and backend services.
Video editing pipeline
Designed and built the video editing pipeline from scratch: timeline, frame-accurate playback, processing and export with FFmpeg/WASM.
Backend licensing service
Designed and shipped a serverless licensing service with Node.js, Express and Upstash Redis, enforcing per-device rules and idempotent activations.
Architecture, reliability and collaboration
Improved the architecture, security and reliability of core flows, collaborating daily in English within a real review-driven release cycle.
