About Me

I’m not here to impress -> just to build. I turn ideas into working products, fast and clean. No buzzwords, no drama. I care about solid code, real results, and keeping things simple. That’s it.

I’ve worked across different stacks and teams, learned that clarity beats complexity every time. So I focus on what matters: collaboration, performance, and maintainability. Tech changes fast, good work stays consistent, and that’s what I aim for.

Featured Projects

Voice to text converter

HabitChain

HabitChain is a dApp that turns self‑discipline into a financial commitment. Users lock funds on their own habit, complete daily check‑ins, and if successful, reclaim their stake plus yield. If they fail, the locked fund is slashed to the protocol treasury (or, in groups, redistributed to successful peers).
