Stabilize expired-order cleanup job and prevent database pool exhaustion Working with Bilal has been excellent. He handles payment-critical and backend tasks with a level of care and professionalism that genuinely makes a difference… he understands the codebase context before making changes, anticipates problems, and delivers solid solutions, not just what was asked. His hourly rate is higher than average, but it pays off: less rework, less risk in sensitive areas (like payments), and clear communication throughout. I recommend him without hesitation to anyone who needs a reliable senior developer.

Full-Stack Developer Needed for SaaS Platform Development Bilal did an amazing job on our MVP. He’s extremely professional and very perfectionist in the best way. When we hit the deadline, he even took an extra week to polish everything, fix all bugs, and make sure the product was stable, without charging me for the additional work.

Even after the contract ended, he continued helping and supporting me whenever an issue came up. He’s reliable, human, and truly cares about the quality he delivers. His team is great as well. I highly recommend him.

Alongside that I work with founders and CTOs in the US and Europe on multi-tenant SaaS platforms, subscription and webhook infrastructure, and AI features that hold up in production rather than in a demo.

Architecture review before any code is written.

I use Claude Code and Cursor daily. They make me faster; they don't make the decisions. Code is reviewed before it reaches your repo, and I'll tell you where the model got it wrong.

Sprint delivery with a full review and a written plan roughly every 10 working days, plus async Loom updates between. I flag technical tradeoffs when I make them rather than after they bite you. Post-launch support included.

Based in Pakistan - reliable overlap with US mornings and EU afternoons. Response under 4 hours.

If you're building something serious, send a MESSAGE or INVITE me to your job. I offer a free 30-minute technical strategy call before any engagement.
