I enjoy solving hard problems at the intersection of security and usability. I’m good at diving deep into smart contract vulnerabilities, cryptography, and system design, and I like turning those insights into practical tools. What drives me is the idea that Web3 can embed fairness and trust directly into code, giving people systems that are both transparent and private.

Some of my most interesting work has been Project Sentinel, where I designed a decentralized trust and adjudication layer for UPI with on-chain reputation, immutable audit trails, and ZK-proofs for “Resolve Now” disputes. I also contributed to VaultX, proposing a Zero-Knowledge passwordless login module to make authentication safer.

Hackathons have been a big part of my journey—I’ve built projects like MetaCard YieldFlow (DeFi-linked spending & on-chain reputation) and PromptChain (NFT marketplace for AI prompts). Each project has taught me how to go from idea → prototype → demo under pressure, which I really enjoy.

Above all, I’m curious, security-driven, and motivated to build things that protect users while pushing Web3 forward.
