## About

I'm a Java backend developer with hands\-on experience building secure, scalable RESTful APIs using Spring Boot, Hibernate/JPA, and MySQL — sharpened through a 6\-month internship developing a full\-scale Digital Payment Management system\. During my internship at QSPIDERS, I designed and built REST APIs for transaction processing, integrated Spring Data JPA for data persistence, and connected a React\.js frontend for real\-time payment visibility — all tested rigorously with Postman\. I also built a full\-stack Handwritten Document Digitizer using Python, Flask, MongoDB, OCR APIs, and React, which gave me end\-to\-end product experience across backend, AI integrations, and frontend\. I'm passionate about clean architecture, solving practical problems with code, and continuously growing\. Currently targeting backend or full\-stack developer roles where I can contribute on day one — and keep learning fast\. Software Developer Intern — Digital Payment Management QSPIDERS · Oct 2025 – Mar 2026 · Chennai, India Engineered a full\-stack digital payment system using Java, Spring Boot, and Spring Data JPA — enabling secure transaction processing with an 8\-table MySQL database schema Designed and implemented 12\+ REST API endpoints for payment initiation, record retrieval, and status updates; validated all endpoints via Postman before release Integrated a React\.js frontend allowing users to view live payment history and initiate transactions — reducing backend\-to\-UI integration time by coordinating data contracts upfront Applied MVC architecture and Hibernate ORM best practices, reducing raw SQL dependency and improving data consistency across services Full\-Stack Developer \(Project\) — Digitize & Translate Documents Personal Project · May 2025 Built an end\-to\-end document intelligence platform using Python \(Flask\), React\.js, MongoDB, and GenAI/OCR APIs — converting handwritten documents into editable, translated digital text Developed REST API layer in Flask to handle document uploads, OCR processing, and AI\-based translation, integrated with a React frontend for real\-time previews Implemented CRUD operations via MongoDB for document storage, retrieval, and management — demonstrating cross\-stack architecture \(frontend \+ backend \+ database \+ AI integration\)
