Job Success
Lahore, Pakistan - 7:06 pm local time
Senior Back-end Python, Laravel/PHP Engineer with 8+ years, $300K+ earned on Upwork, and 17,000+ hours delivered.
I specialize in building and modernizing production Python, Laravel, PHP, and full-stack applications (React, Next.js, Node.js), the kind of systems businesses run on every day.
If you have a growing SaaS product, a legacy application that needs modernization, or a new build that needs a senior full-stack partner who ships reliable code, that's where I fit.
I work across the full stack: Laravel/PHP backends, React/Next.js frontends, REST APIs, third-party integrations, and cloud deployment (AWS, DigitalOcean, Docker). I also work with modern AI/LLM APIs (OpenAI, Claude) for teams looking to add intelligent features to their applications.
