I’m Makbel Alemayehu, a junior full-stack web and software developer based in Addis Ababa. I enjoy building practical products end-to-end, especially when there’s a real concurrency or reliability problem to solve—like the atomic MongoDB update I implemented to prevent double-booking in a ticketing marketplace. I work comfortably across the stack with Next.js and TypeScript on the frontend, and Node/Express with MongoDB or PostgreSQL on the backend. Before focusing fully on software, I spent four months in hands-on IT support at Bethzatha Hospital, keeping Linux systems running smoothly for non-technical staff. I’m also passionate about teaching and learning—through one-on-one tutoring for Python, Java, C++, and web fundamentals—where I help students turn confusing concepts into something they can apply. I’m currently continuing to develop event and wedding platforms, plus an online learning system that puts secure role-based access and solid database design first.…I’m Makbel Alemayehu, a junior full-stack web and software developer based in Addis Ababa.
