Python Backend Developer | I Build & Ship Real Projects — Not Just Theory | Django · Flask · CEH Certified

About

I spent 2 months working real cybercrime cases with Telangana Police — and that's when I understood what "writing code that matters" actually means. I'm a Python & Django backend developer with a background in cybersecurity. I don't just build apps — I build them with security baked in from line one. That's a rare combination, and it's what makes my work different. Here's what I've built and shipped: 🔧 Tweet App Clone — Full Django + SQLite CRUD app with user auth, deployed live 🤖 GitaBot — AI chatbot built on Flask + Google Palm API, answers 100+ Bhagavad Gita queries via semantic search 🧾 Construction Billing System — Generates PDFs with QR-based invoice verification 🍽️ Restaurant POS System — Real-time order management with Flask-SocketIO + Zomato/Swiggy API integration Beyond the code, I hold a CEH (Certified Ethical Hacker) certification and completed an internship at the Women Safety Wing, Telangana Police — where I automated case sorting with Python and cut report processing time by 40%. I also completed cybersecurity simulations with Tata Group, AIG, and Mastercard through Forage — applying OWASP, NIST, and SOC workflows to real enterprise scenarios. 🛠️ My Stack: Python · Django · Flask · REST APIs · SQLite · PostgreSQL · Nmap · Burp Suite · Git · Linux 🎓 B.Tech in Computer Science (Cybersecurity specialization) — Guru Nanak Institutions, 2025 I'm currently working as a Web Developer at Ruffleberry India and actively seeking my next role in backend development or application security. If you're building something that needs a developer who cares about both code quality and security — let's talk. 📬 DM me here or reach me at: rahuulupadhyay.netlify.app
