You will get bugs fixed in your React or Next.js app, with the cause explained
Project details
Bugs usually stay unfixed for one of two reasons: nobody can reproduce them reliably, or someone patched the symptom and the real cause is still there.
I do it the other way round. I run your project locally, reproduce every bug on your list, then trace each one to what is actually causing it before changing anything. You get told what was wrong, not just that it is fixed.
What I work on:
• React and Next.js apps, JavaScript or TypeScript
• State bugs, re-render and performance issues
• Layout and responsive problems
• Broken API calls, auth and routing
• Build and deployment errors
What you get:
• Every bug on your list fixed, or an honest explanation if one is not reproducible
• A short note per bug: what was wrong and what I changed
• The complete source code
What I need from you:
• The bug list with steps to reproduce
• Repository access and how to run the project locally
I have spent three years maintaining production systems that real businesses depend on daily, including a laboratory platform running in over 1,000 labs. Most of that work was finding out why something broke and making sure it stayed fixed.

About Mohamed
React & React Native Developer | Web & Mobile Apps | Next.js
Zagazig, Egypt - 6:49 pm local time
Over 3 years I've shipped systems that real businesses use every day: a laboratory platform serving 1,000+ medical labs, an HR system for companies with 300+ employees, and a clinic management system unifying hundreds of clinics across Iraq, Saudi Arabia, and Egypt.
WHAT I DO
- React / Next.js web apps - TypeScript, Tailwind, shadcn, Material UI, Ant Design
- React Native mobile apps - iOS + Android, offline-capable, full RTL and multilingual support
- Electron desktop apps that keep working without an internet connection
- REST API integration and state management with Zustand, Redux, and TanStack Query
- Databases: PostgreSQL, MySQL, MongoDB, SQLite
RECENT WORK
Finance mobile apps in React Native with Arabic/English localization and offline sync.
SELECTED PROJECTS
Unimedica - Medical laboratory platform. Built the front end plus an offline Electron desktop client, now serving 1,000+ labs.
Ibn Sina Clinics - Unified management and patient-history system used across hundreds of clinics.
Zone HR System - Admin dashboard and employee mobile app for companies with 300+ staff.
HOW I WORK
I ask questions before I write code, I give you honest timelines, and I tell you early if something is going to slip. I work comfortably in English and Arabic, which matters if your users, your team, or your interface are in both.
If you're building a web or mobile product and want someone who ships working software rather than a demo, send me a message describing what you need. I'll tell you honestly whether I'm the right person for it.
Steps for completing your project
After purchasing the project, send requirements so Mohamed can start the project.
Delivery time starts when Mohamed receives requirements from you.
Mohamed works on your project following the steps below.
Revisions may occur after the delivery date.
Reproduce every bug
I run your project locally and reproduce each bug before touching any code. If one of them isn't reproducible I tell you straight away rather than guessing.
Fix the cause, not the symptom
I trace each bug to what is actually causing it and fix it there. Quick patches that hide a problem tend to bring it back later in a worse form.
