Led design and development of high-performance Go backends to ingest and process blockchain data from EVM-compatible chains at scale. Implemented a proprietary indexing solution reducing smart contract query latency by 40%, enhancing developer experience. Conducted security audits and gas-optimization reviews for Solidity contracts in collaboration with DeFi and NFT projects. Maintained distributed systems handling terabytes of data with 99.9% uptime and data integrity. Collaborated with product and engineering teams to launch real-time monitoring features for smart contract interactions. Spearheaded integration of a transaction-simulation debugging tool across network states to accelerate debugging.

Engineered scalable microservices and robust RESTful APIs using Node.js and TypeScript to support the Assets team with high transaction volumes. Built responsive front-end interfaces with React for asset management. Integrated third-party blockchain data sources and standardized token models (ERC-20, ERC-721) to unify asset representation. Migrated legacy systems to a modern microservices architecture on AWS, boosting resilience and scalability. Worked with cross-functional teams to deliver features with a security-first approach.

Designed and implemented a unique integration platform for Cisco Silicon One architecture using Python, creating complex networking scenarios for testing. Developed internal tools and web interfaces to visualize and debug system performance, improving testing efficiency. Gained deep expertise in networking protocols and low-latency system design while collaborating with a globally distributed R&D team. Maintained high code quality through unit testing, peer reviews, and agile cycles; automated regression testing procedures, reducing testing time by 30%.
