What I'm looking for

I’m looking for a product-focused team where I can ship backend and mobile features, collaborate on security and testing, and grow fast through hands-on ownership, code reviews, and mentorship.

I’m a computer science student at Punjab University College of Information and Technology (PUCIT), and I’ve been working as a Freelance Software Developer since Dec 2025. I build features end-to-end—from backend modules in Python to mobile experiences in Flutter and Kotlin—while staying disciplined about testing, CI/CD, and maintainable code.

Recently, I designed and integrated a Python backend module to generate FBR-compliant digital invoices (tax calculation, formatting, and automated PDF generation) into a MySQL-based workflow. I also contributed to OWASP ZAP extensions by adding unit tests to improve regression safety and worked on Haiku OS patches through Gerrit, including Btrfs Zstd decompression logic and refactoring kernel error handling. In parallel, I’ve built an XGBoost fair market value predictor for real estate pricing (R² = 0.89) and developed a bus tracking app that reduced battery consumption by 30% with near real-time updates.
