Seven years. Four industries.

Airlines, hospitals, bitcoin miners and cargo.

I make the hard systems feel simple.

Full-stack developer · Dubai, UAE

I build web apps, websites and custom systems. Angular, React and Node.js, from the first screen to the server it runs on.

Web apps, websites and custom systems

Have something you need built, fixed or connected? I take projects from first sketch to a system running in production, and I stay close to the people who will use it.

01 / 06

Web applications

Dashboards, portals, booking flows and admin tools that people use all day. Angular, React, TypeScript and Node.js.

Like the Saudia and Etihad booking flows, and monitoring for 300,000+ miners. Web app development in Dubai →
02 / 06

Websites

Fast, search-ready websites with motion that still works on a phone. Built to load quickly and rank.

Like the one you are scrolling now.
03 / 06

Custom systems and integrations

APIs, microservices and the glue between systems. Payments, HL7 healthcare data, POS and inventory, Kafka and RabbitMQ.

Like the prescription pipeline to DHA and HAAD.
04 / 06

Mobile apps

Flutter and React Native apps that share one backend with the web app.

Like the Winsoft doctor app and Dawa24 medicine delivery.
05 / 06

Upgrades and rescues

Slow, fragile or outdated system. I split monoliths, move live databases without downtime and fix deploys.

Like cutting update downtime at Phoenix to near zero.
06 / 06

Cloud and DevOps

Docker, AWS, Azure DevOps CI/CD and Nginx, so your system ships safely and keeps running.

Like deployment cycles cut by 40%+.

The story so far · 2018 to now

Five reels, one engineer

KITCHEN › SECTION › RIDER › TABLE

A whole restaurant group, on one screen.

Right after graduating I co-built a point-of-sale system for a multi-brand, multi-branch restaurant company. Orders route to the right kitchen section, delivery runs through Careem, Talabat or in-house riders, and every dish is costed from its recipe.

MSH|^~\&|UMF|… HL7 › HAAD / DHA › PBM

Medical records that follow the patient.

I worked on the Unified Medical File, an EMR that exports patient records to formats like HL7. I built the doctor app end to end and the pipeline that sends prescriptions to health authorities and on to insurance billing.

Along the way I helped move a monolith to microservices, built about 30% of the new APIs and led Dawa24, a medicine delivery app, as a team of two.

Booking flows for millions of travellers.

I built Saudia's booking system, worked on Etihad's manage-booking flow and its add-on services, and added purchasable services for Royal Air Maroc. Multi-step journeys where one broken step means a lost seat.

300,000+ MINERS · UAE · OMAN · UPTIME · COST PER MINER

No miner goes dark without anyone noticing.

Before, a miner could drop offline and nobody would know. I built per-miner monitoring from scratch, tracking uptime and electricity cost, plus the CI/CD on AWS and the Kafka and RabbitMQ messaging behind it.

Keeping global shipping moving.

Hired for the front end, I now lead it on active projects and also cover APIs, SQL, DevOps and release management. I work directly with business analysts and clients on how their systems connect.

Questions clients ask

Before we start

What kind of projects do you take on?
I build web applications, websites and custom software systems. That includes dashboards, booking and admin portals, APIs and integrations, mobile apps, and upgrades to existing systems that have become slow or hard to change.
Where are you based and who have you worked with?
I am Muhammad Rehan, a full-stack developer based in Dubai, UAE. I have built software for airlines, healthcare providers, a bitcoin mining operator, restaurants and a global logistics company.
Which technologies do you use?
I work with Angular, React and TypeScript on the front end, Node.js and Spring Boot on the back end, Flutter and React Native for mobile, SQL and MongoDB for data, and Docker, AWS and Azure DevOps for deployment.
Can you fix or upgrade an existing system?
Yes. I have led a monolith to microservices migration, run a live database migration using a parallel stack, and brought update downtime close to zero for a mining platform with 300,000+ machines.
How do I start a project with you?
