Backend & full-stack software engineer building production-grade web, mobile, and AI applications.
IndiaWhat I'm looking for
I’m a Backend and full-stack developer with internship experience building production-grade web, mobile, and AI-driven applications. I enjoy owning features end-to-end—from architecture to deployment—and delivering measurable impact.
At Vizilare Technology, I architected an end-to-end AI-powered grading system for handwritten exam sheets. I reduced per-paper processing time from 103s to 36s (3× speed-up), re-engineered a multi-engine OCR pipeline to raise question-detection accuracy from 52% to 96%, and improved grading accuracy (25% → 51%) while cutting manual teacher review by 89%.
I also developed a full-stack web portal with React, Vite, Tailwind CSS, and a Flask REST API—adding batch processing, PDF export, and WhatsApp delivery. I strengthened reliability by adding unit/integration tests and fixing a critical caching bug using content-hash keys.
Previously, as a Mobile App Development Intern, I shipped production cross-platform Android applications using React Native and Kotlin (Jetpack Compose). I delivered secure onboarding and real-time data synchronization with Firebase Authentication/Firestore and REST APIs in an Agile team using Git/GitHub version control.
