- Led a team of 4 engineers and drove a redesign of the platform into modular microservices (NestJS / TypeScript / PostgreSQL), authoring the project requirement documents and defining service boundaries. - Integrated third-party APIs (Bitget) to power crypto-to-crypto spot trading against their order book and to stream live market price-feed data across the exchange Implemented Bitcoin Lightning payments via IBEX, enabling users to send and receive BTC instantly. - Diagnosed and resolved API performance bottlenecks, cutting response times by restructuring how assets and market data were modeled and served to reduce database load.

- Architected and shipped a full-stack cross-chain bridge end-to-end as sole technical lead — React/TypeScript frontend with dual wallet support, Node.js/Express relayer, MongoDB persistence, and Solidity + Rust/Anchor contracts — running $100K+ in daily volume at acquisition. - Designed a stateful transaction pipeline (pending → validating → processing → released) with tx-hash-based idempotency guards and replay protection, making a multi-worker system safe to run concurrently. - Built white-label infrastructure relicensed to multiple clients from one codebase, with a Redis-cached REST API, event indexer, and Docker/CircleCI multi-environment deploys.

- Led development on a gold-pegged DeFi platform — the React/TypeScript dashboard plus smart contracts — and onboarded 3 engineers as the protocol scaled. - Built subgraphs (The Graph) indexing vault activity and computing real-time APY, ratios, and deposit metrics, surfaced on the frontend dashboard. - Built the collateralized debt position system (mint-against-collateral, on-chain liquidation thresholds, gas-optimized storage) with frontrunning resistance, tested and gas-profiled under Hardhat.
