Built scalable RESTful APIs using Node.js and Express.js for complex financial transaction flows — handling channel balances, reconciliation logic, and high-frequency API endpoints with a focus on clean, reusable server-side architecture. Developed and maintained full-stack features using the PERN stack (PostgreSQL, Express.js, React.js, Node.js) and MERN stack (MongoDB, Mongoose, Express.js, React.js, Node.js), contributing to multiple production modules. Designed and optimized PostgreSQL and MongoDB schemas via Prisma ORM and Mongoose — enforcing proper indexing and relational integrity, reducing query time by 50% and cutting average API response time from ~4s to ~1s under production load.
