Hi there 👋

I'm a Software Engineer. By day, focused on building scalable systems with modern tools like NestJS, NextJS, GCP. By night, I'm on a personal mission to master the fundamentals of computer science.

This means going deep dive into the fundamentals. Studying C, Operating Systems, and Networking, to connect the dots between the high-level applications I build and the low-level systems they run on.


🔭 Currently Learning & Building

My current focus is on bridging theory with practice:

  • 🧠 C Language Deep Dive: Systematically mastering memory management, pointers, and low-level programming concepts. I document my progress and key insights in my C Lab Logs.
  • ⚙️ Operating System Internals (XV6): Currently learning Operating Systems through a guided Operating Systems Camp provided by CusDeb.com. The camp follows MIT’s xv6 approach, blending theory with hands-on exploration of kernel design, system calls, and process management. I document my ongoing progress and experiments in the XV6 Lab Logs.
  • 🤝 Open Source Camp: Joining the Open Source Camp by CusDeb.com, focused on learning how real-world open source collaboration works. from licensing and issue hunting to contributing code. After early exercises like porting OpenBSD userland utilities to Linux, the camp’s main target is contributing to Nextcloud, an open-source alternative to Google Workspace. My first contribution: nextcloud/server#55992.
