Profiles & Competitive Platforms


Open-Source Repositories


Why I Build & Share

I create open-source repositories not just to solve problems, but to build reusable knowledge systems.
My goal is to help others learn faster, think deeper, and write cleaner code β€” whether they're preparing for interviews, building backend systems, or exploring rare algorithms.

I believe in architectural clarity, modular documentation, and sharing patterns that others can build on.
Every repo I publish is part of a long-term vision: to grow as a backend engineer, contribute to the developer community, and make technical knowledge more accessible.

I'm still learning β€” and I share as I go.


Contact & Collaboration

If you're building systems, solving hard problems, or exploring algorithmic architecture β€” let's connect.
I'm open to freelance work, backend roles, and open-source collaboration.
