– Architected a privacy-first ephemeral chat application featuring self-destructing rooms with a 10-minute Redis TTL, ensuring zero long-term data persistence across all sessions. – Implemented end-to-end type safety using ElysiaJS + Eden Treaty, Upstash Realtime for WebSocket-based instant messaging, and server-side proxy gating enforcing a strict 2-user room limit. – Deployed to production on Vercel across 7 successful deployments; eliminated scheduled cleanup jobs entirely by leveraging native Redis TTL for automatic data expiry.

– Won$200 prize building a full-stack Telegram Mini App enabling merchants to accept TON cryptocurrency payments via existing QR codes (Paytm, PhonePe, Google Pay) without new infrastructure. – Engineered 10 screens and 13 components including a camera-based QR scanner, slide-to-confirm payment gesture, real-time balance fetching from TON blockchain, and a statistics dashboard. – Deployed 16 production builds on Vercel; integrated TON smart contract with opcode-based QR registration, on-chain merchant verification, and gasless read queries.

– Built a cross-chain ERC-20 rebase token with per-user dynamic interest accrual, overriding balanceOf() to compute compounding interest since the last checkpoint without additional storage. – Implemented a collateral vault contract (deposit/redeem) with role-based access control via OpenZeppelin AccessControl, separating mint/burn privileges from ownership. – Integrated Chainlink CCIP for secure cross-chain token transfers; wrote comprehensive Foundry test suite covering mint, burn, interest accrual, and edge cases.

– Completed end-to-end full stack training covering frontend, backend, databases, and deployment best practices.

– Mastered advanced smart contract testing, fuzz testing, and deployment pipelines using the Foundry framework.

– Strengthened frontend fundamentals with modern React patterns, hooks, and reusable component architecture.
