I’m a passionate Computer Science B.Tech graduate with a strong interest in the end-to-end software development process—from conceptualizing ideas to building and implementing solutions. I’m enthusiastic about continuous learning and self-improvement, and I aim to contribute to meaningful projects by creating robust, scalable applications.

In my Backend Developer intern role at Melchizedek Technologies Pvt Ltd (Do Dash), I implemented geofencing functionality for a quick commerce application using MongoDB geospatial storage and querying. I also built a robust product search capability with autocomplete using MongoDB Search, created a file upload system with Multer and Amazon S3 for vendor onboarding, and leveraged Firestore real-time synchronization for near real-time updates.

I continued strengthening user-facing backend features by integrating push notifications with Expo and using Ola Maps APIs to calculate delivery ETA by factoring in traffic conditions and distance. Previously, as a Frontend Developer intern at PRELKO Private Limited (Morff), I built PDF and email templates using HTML and CSS and developed/maintained user interfaces across multiple Next.js projects.

My projects reflect how I approach secure, practical APIs: I developed a Customer Identity Reconciliation API with Node.js, Express, PostgreSQL, and Sequelize ORM, and built an IMF Gadget Management RESTful API with JWT-based authorization, CRUD with soft delete (decommissioning gadgets with timestamps), and Postman documentation. I deploy and validate work with platforms like Render, and I enjoy turning requirements into clean, reliable systems.
