I developed a suite of NestJS REST APIs for Motilal Oswal, exposing investor and portfolio data through client-defined response contracts. At KFin Technologies, I also built Node.js and Express.js APIs for XALT AIF TA operations using AWS Lambda and API Gateway.
I worked on MongoDB-backed workflows, revision-based history, and retry handling for backend failures. At CGI, I developed REST APIs for Trade 360 and investigated production API errors and database deadlocks; more recently, I contributed small API changes to an existing Python codebase while volunteering.
