⚀ Turning caffeine into production-ready code
⚁ Backend systems architect who occasionally touches the frontend (when necessary)
⚂ Building AI tools and debugging why the LLM thinks it's a poet
I love crafting production-grade software that solves real problems.
Gostman
A native, privacy-first API client built with Wails (Go + React). 10x lighter than Postman with native support for REST, GraphQL, and WebSockets. 100% local and private.
Tech Stack
Un-Nexted
De-mystifying the meta-framework. A raw implementation of Next.js core features like SSR, hydration, and file-system routing from scratch, revealing the magic behind modern web frameworks.
