⬡ ABOUT

WHO AM I

Java Backend Developer with hands-on experience in Spring Boot, REST APIs, and secure system design. I build production-ready systems with JWT authentication, role-based access control, and automated email workflows. Completed Infosys Springboard internship delivering clean, testable backend solutions. Passionate about developer tooling — published a VS Code extension to the marketplace. I don't just write code; I engineer systems that scale, secure, and solve.

CLOUDBRIDGE — SECURE MULTI-CLOUD FILE TRANSFER PLATFORM

⬤ LIVE GITHUB

A secure multi-cloud file transfer and storage system designed for large-scale file handling. Users upload files, compress them into lossless .7z archives, and distribute them across multiple cloud providers including AWS S3, Google Drive, Azure Blob Storage, Oracle Cloud, and Backblaze B2. The system generates secure, expiring download links with password protection, download limits, analytics tracking, and auto-deletion scheduling — all without requiring user login.

Built with a SaaS-oriented architecture using Spring Boot microservices, scalable cloud integration, and automated file lifecycle management.
