What I'm looking for

I'm seeking a Junior Full-Stack Developer, Node.js Developer, or Associate Software Developer role where I can build production web applications and backend APIs.

I've built REST APIs and backend workflows at Regrip India for six ERP modules covering inventory, sales, claims, services, branch management, and transaction history. I implemented role-based access control, branch-level restrictions, validation, search, filtering, and pagination using Node.js, Express.js, Sequelize, and MySQL.

I also built invoice-processing workflows with the Google Gemini API and integrated backend services with React.js interfaces. Through internships at Regrip India and Systrac, I've worked with MongoDB, JWT authentication, database optimization, error handling, and end-to-end API integration.
