Experience
Junior Software Engineer
Mar 2023 — Present
ERP System – Backend Development (Cognizant) Collaborated in a 10-member team to build a scalable ERP system from scratch for managing inventory, orders, and user roles. Developed 40+ RESTful APIs using NestJS, TypeScript, and TypeORM, following clean architecture and modular design. Designed PostgreSQL database schemas and optimized multiple slow APIs, reducing response times by up to 40%. Took ownership of a small client-requested module: gathered requirements, designed schema, and implemented APIs. Integrated JWT-based authentication and maintained Swagger documentation for improved security and developer usability. Worked in a Dockerized environment aligned with AWS deployment setups. Collaborated closely with frontend and QA teams to ensure smooth sprint deliveries under Agile methodology.
