Client reviews

5.0★ on Upwork

Verified reviews from clients we have shipped with.

“We had an existing codebase with a fairly complex setup, and Ahsan quickly got up to speed. He has since implemented numerous new features, improvements, and updates while keeping the codebase aligned with the latest versions. He is highly responsive and has often gone the extra mile — including working extended hours — to help us meet important deadlines.”

Michela

Product Owner · App Updates & Maintenance

“Ahsan is without doubt one of the best React-Native devs I have worked with. Super smart, takes initiative, pays attention to detail. Very good communicator. I will certainly be on the lookout to hire him in my upcoming project. Well done Ahsan. Looking forward to working with you soon again.”

Salman Saif

Founder · React-Native Development

“Ahsan was a pleasure to work with! Full executed all tasks to the highest standard. Took feedback well. Took initiative when it came to project design and execution. Would love to work with him again in the future!”

Steve Evrard

CEO · Product Development

“Ashan is a competent developer and made a good-faith effort to address concerns and get the engagement to a satisfactory place. I appreciated his responsiveness and willingness to make things right.”

React Native / Expo Developer for Live Christian Wellness App QA & Security Review · Jun 9, 2026

“Ahsan delivered excellent work on a React Native mobile app with AI-powered backend integration. His technical execution was strong across the board — clean architecture, thoughtful state management with Redux Toolkit and persistence, solid React Navigation setup, and performance engineering that brought streaming latency from 7 seconds down to under 3. What really stood out was his professionalism. When I decided to pause the project to focus on another direction, he handled it with grace and delivered an exceptional handover document — detailed architecture notes, environment variable documentation, pending roadmap items, and clear explanations of design decisions. He also proactively offered to adjust the milestone to reflect partial completion, which shows the kind of integrity you rarely see. Communication was consistent and clear throughout. He flagged technical tradeoffs, asked smart questions, and delivered on what he committed to. Would absolutely hire again for React Native, Expo, or full-stack mobile work. Highly recommended.”

Expert Full-Stack Developer (React Native & Next.js) – 5+ Years Experience · Mar 14, 2026

“Ahsan was a pleasure to work with and delivered outstanding results on our mobile app stabilization project. He quickly identified and resolved complex crashes, ANRs, and issues in a legacy React Native / Expo environment while staying fully within the existing stack, which was a key requirement for this project. He is incredibly fast, highly knowledgeable, and communicates clearly throughout the process. Ahsan worked smoothly with both our marketing team and directly with the client’s team, helping everyone understand what was happening technically and what was being fixed. Because of the quality of his work and how efficiently he stabilized the app, we are continuing our relationship by contracting him to remain onboard each month. I would absolutely recommend him for complex mobile debugging, stabilization, and production app work.”
