Not tutorial apps. Not sandboxes. Real systems — running right now, serving real people.

• 🚆 Railway Vendor System — cut login from 30–60s → under 5s, data fetch from 2 min → 10s. Joined as bug fixer; consistently resolved issues faster than the existing team — manager handed full ownership across 4 Indian Railways divisions.
• 🍽️ QR-Based Train Pantry Ordering System — unique QR per train, live vendor menu updated in real-time, 3-role system (User · Vendor · Admin); co-built with teammate.
• 🗺️ GeoTech Garbage & Material Management System — GPS-tagged photo reporting, full 6-role lifecycle: report → assign → clean → verify → approve → notify; co-built with teammate.
• 🎓 ID Card & Face Verification System — multi-role workflow with QR codes and face detection, used by 10,000+ students and staff at 20+ institutes. Built entire backend solo.
• 🏛️ Government of India Copyright holder — Reg. L-151429/2024 for an AI image forgery detection system built with CNN + ELA.
• 📄 3 published research papers in Computer Vision and NLP.

I move fast, write clean code, and take full ownership of what I build.

Dec 2025 – Present

Railway Vendor Management System — 4 Indian Railways Divisions, Maharashtra & Chhattisgarh

• Joined as bug fixer; resolved critical issues faster than senior developers — manager handed full project ownership
• Now sole maintainer across all 4 divisions with daily commits to private repository
• Optimized login 30–60s → under 5s, data fetch 2 min → under 10s (12× improvement each)

QR-Based Train Pantry Ordering System

• Co-built (50-50) with 1 teammate via Git + Google Meet
• Designed full UI; each train has a unique QR opening a live vendor menu with real-time updates
• 3-role system: User orders → Vendor receives and delivers → Admin monitors sales, ratings, complaints

GeoTech Garbage & Material Management System

• Co-built (50-50) with 1 teammate via Git + Google Meet
• GPS-tagged photo reporting with auto-captured coordinates; full 6-role lifecycle: report → assign → clean → verify → approve → notify
• Includes Material Storage module for railway scrap inventory with live weight tracking

Institute ID Card & QR Verification System — 20+ Institutes, 10,000+ Users

• 2-person team via Git + Google Meet; solely built entire backend
• Multi-role workflow: Admin → Org Admin → Employee/Student with face detection and QR-based verification
• Maintained direct client communication throughout delivery

Multi-tenant SaaS bug tracking with AI-powered triage — production-grade from the ground up.

• RBAC with Admin, Developer, and Tester roles — scoped data access at every layer
• AI triage — auto-assigns severity, deduplicates issues, generates reproduction steps via OpenAI

• Java 17 · Spring Boot 3 · Spring Security 7 · MySQL 8 · React · Redux · OpenAI API · Docker

Real static analysis — not just LLM opinions.

• AST parsing via acorn — structural analysis, not surface-level feedback
• Cyclomatic complexity scoring + maintainability metrics across 10 languages
• GitHub URL mode — paste any public file URL and review it directly
• Chose Groq over OpenAI — 14,400 free req/day, same SDK, zero cost; stateless backend
• Node.js · Express · React 18 · Vite · Groq API (llama-3.3-70b) · acorn AST

AI system for detecting image manipulation — backed by a government copyright and 3 research papers.

• CNN + ELA (Error Level Analysis) to detect JPEG artifact manipulation with high accuracy
• REST API with heatmap overlay showing exactly where tampering occurred
• Foundation for 3 published papers in AI/ML conferences
• Python · TensorFlow · OpenCV · Flask · CNN · ELA

I'm looking for SDE-1 / Backend / Full Stack roles. Immediate joiner — open to relocation and remote.

If you need someone who ships real software and takes ownership, I'd love to connect.
