Lead Developer — Dental Note AI (Ongoing)

Ahmed is our lead developer on a Django/React clinical SaaS platform, closing this project purely for admin housekeeping before the next one opens. Full technical authority, honestly earned: he verifies claims by running the code, corrects himself in writing, and proves fixes by breaking them first. Communicates with total clarity for a non-technical founder. Five stars is the ceiling, not the measure. We continue on the next project. [04 May, 2026] Honestly, I don't want to write this review. I'd rather keep Ahmed to myself. But fair is fair: in 14 years across Freelancer, Fiverr and Upwork, with well over AUD$300K spent on projects in that time, Ahmed is a country mile ahead of any freelancer I've ever worked with. And that is genuinely saying something. Hire him at your peril — you'll never want anyone else. Denver [02 August, 2026] Brilliant senior developer; his lead is your path to success in development.

Need Canvas developer for Real-Time Stock Charting

Frankly very disappointing end of this project, we thought we hiring a skilled person but he is just an AI user and don’t know coding and wasted our months and because of that our reputation got ruined completely. We suggest think twice before hire him.

RideBorder Switzerland - Carpooling MVP

Great work, Ahmed! ? The progress is impressive, and it's clear you've put a lot of thought into building a complete MVP rather than just a prototype. Having the full passenger and driver flow working live, along with the admin dashboard, CI/CD, and monitoring, shows strong technical execution and attention to detail. The live demo makes it easy to experience the product end-to-end, which is a huge plus. Looking forward to the next milestone with payments enabled. Excellent job! ?
