The person behind the code
I'm Nafi Shvinger - a full-stack and mobile developer with a background that's anything but conventional. Before writing a single line of code, I spent years immersed in intensive Talmudic study at top yeshivot, a discipline that sharpened analytical reasoning, precision, and structured thinking in ways no computer science course could replicate.
Today I build React Native / Expo mobile apps, Node.js / Strapi backends, and everything in between. At DOJO, a live social wellness platform, I shipped production features end-to-end: a gamification system built on cron jobs and webhooks, real-time chat with Socket.io, secure S3 media delivery, and a config-driven refactor across ~86 files - with 13+ PRs merged after senior review. I also authored a 9-course, 130+ lesson Hebrew programming curriculum that my classmates studied from.
I'm an AI-native engineer: Claude Code is my primary development environment, and I build with MCP servers, agent workflows, and custom AI skills I author myself. When I'm not coding, you'll find me studying Daf Yomi, running long distances, or building tools that bridge my two worlds.
