I’m Kubsa M. Etefa

I build production-ready web and mobile products that scale — focused on real‑time interactions, lightning-fast performance, and engineering for reliability. From TypeScript backends and Next.js frontends to React Native apps and WebGL-driven demos, I ship end‑to‑end systems that teams and customers rely on.

Recent work includes architecting resilient real‑time services with WebSockets and Socket.IO, delivering cross‑platform apps with React Native, and embedding interactive 3D models for immersive product demos. I measure impact through faster load times, stable realtime pipelines, and code that’s easy to evolve — outcomes your team can observe and quantify.
