10+ core product delivered with 5+ star ratings and reviews. Among us, I might be more interested in your new idea.
Selected work (all verifiable on UpWork)
- Solar design SaaS (US, name kept private), used by solar contractors for site surveys and 3D PV-system layout. I was Core Product Engineer there for 20 months, through to the end of the engagement, and owned the Three.js panel-layout editor including the linear algebra for geometrically accurate roof-mounted placement. I rebuilt its scene-builder performance from 18-20ms per frame (visible frame drops) to 1.5-3ms. The team cited my "commanding knowledge of linear algebra." I also ran their technical interviews, screening 4 candidates and helping select 2.
- Short-form video platform (live), built a reusable subtitle-rendering engine with animated text overlays. Shipped ahead of schedule; the module was reused across other products. Client: "finished everything ahead of schedule... I definitely recommend him."
- Repeat Patterns (production), a web-based seamless repeat-pattern editor in Fabric.js with real-time preview and export. Client praised "mastery of FabricJs" and "best engineering practices."
- fabric-video-editor (open source, 570+ stars), a browser video editor with animation and transitions you can read end to end before you hire me.
Working Style:
- Jira/Linear, with proper status changes, and faster unblocking
- Github/Gitlab with CI/CD for lint/test.
- Vs Code, iTerm2.
- Claude Max (optional, as per project policy)
