About Me

Muhammad Junaid Javed, Senior Full-Stack Engineer

Freelance & Remote

I'm a Senior Full-Stack Engineer with 5+ years building production SaaS, EdTech, and enterprise platforms end-to-end — from complex backend APIs to performance-critical React frontends.

I care deeply about shipping things that actually work at scale: clean architecture, measurable impact, and code that's a joy to maintain. I actively use AI tools — Claude, GitHub Copilot, Gemini API — not as shortcuts, but as force multipliers that let me build smarter and faster.

Based in Lahore. Open to remote contracts and freelance projects with EU/US teams.
