- Protocol Development: Collaborated in the development and integration of smart contracts for a DeFi protocol, focusing on perpetual trading using a liquidity pool market system. This encompassed market creation, market and limit order placement, position life-cycle management, deposits, liquidations, and automatic deleveraging (ADL) management. Additionally, managed on-chain price feeds using oracles such as Chainlink, Pyth, and API3.- Comprehensive Smart Contract Testing: Conducted extensive testing of smart contracts using Foundry, covering invariant testing, unit testing, and integration testing to ensure robust and secure code.- Backend Job Design: Engineered backend jobs for limit order execution , liquidation and automatic deleveraging (ADL) management of positions in the perpetual market.- Robust API Development: Designed and developed several robust REST API, enabling server-side caching. Utilized Redis for in-memory caching and integrated it with MongoDB to enhance performance and scalability.- Protocol Aggregation: Aggregated various protocols, including GMX V1, GMX V2, and Synthetix, into a single platform. This initiative increased access to liquidity pools, available tokens, and improved overall trade execution.- Integrated smart contracts with React application using Ethers.js and Viem, ensuring seamless data access and interaction within the user interface.

- Designed and tested GraphQL and subGraph queries, resulting in improved performance and a reduction in bugs.- Developed jobs for continuous data fetching from WebSockets and integrated a database for the tokenization of pharmaceutical drugs.- Deployed smart contracts on the Solana ecosystem, including vaults and token contracts.- Enhanced application performance by leveraging Redis as an in-memory data store, enabling rapid information retrieval and significantly reducing latency.- Developed a robust backend infrastructure using Node.js and PostgreSQL, ensuring seamless data retrieval for all users.- Implemented Docker for containerization, standardizing development environments and enhancing deployment efficiency.- Utilized Prisma ORM to write optimized SQL queries, improving database interaction and management.

- Developed and implemented a secure authentication and authorization process using OAuth, along with an integrated rate limiter, effectively reducing unauthorized access.- Deployed smart contracts for crop insurance and wedding items NFT marketplace using ERC1155, and developed APIs for real-world data integration.- Implemented paginated responses on the frontend to handle large data sets efficiently, reducing load times for data-intensive pages.- Integrated MongoDB and PostgreSQL to streamline data retrieval and updates, ensuring robust database management and optimization.
