Backend engineering leader · FinTech · Cairo
I build payment systems that stay reliable when traffic spikes, integrations fail and the business is watching — and I write about the human side of engineering.

The short list — where I write, what I offer, and how to reach me.
Work with me
I’ve spent a decade on the parts of engineering that don’t fit in a tutorial: payments that can’t go down, teams that have to ship anyway, and careers built on purpose.
Career Acceleration
A 1:1 tailored session to help you accelerate your engineering career, CV positioning, career roadmap, and transition to senior & lead roles.
High Concurrency & FinTech
A deep-dive 1:1 session on designing scalable backend systems, Go best practices, high-throughput financial switches, and distributed architecture.
For Teams & FinTechs
For engineering teams building payment switches, ISO 8583 banking gateways, or high-throughput financial infrastructure under PCI-DSS compliance.

About
I’m Mohammed Refat, a backend engineering leader working in FinTech. Most of my days are spent on systems where a millisecond is a business decision: high-concurrency payment microservices in Go, gateway integrations, and the unglamorous security work that keeps cardholder data where it belongs.
I started out as a network administrator, moved through SQL and enterprise billing platforms, and eventually found the work I love — building payment infrastructure that has to hold up when traffic spikes and three integrations fail at once.
Along the way I learned that the hard part is rarely the code. It’s the team around it: how decisions get made, how performance gets measured, how people grow without burning out. That’s what I write about, and what I coach on.
Outside of work I co-founded Hamber-hub, and I still carry lessons from co-founding IEEE Minia and TEDxMinia — the first places I learned that a good idea needs a team more than it needs a genius.
“The job is to make sure the team isn’t winning the numbers while losing the product.”
Writing
I write on LinkedIn, mostly in Arabic, for engineers who are becoming leaders faster than anyone prepared them to be.
Distributed Systems · Physics
At 3 AM in Egypt, Android phones alerted residents before the shaking arrived. A masterclass in combining physics and distributed software engineering.
Engineering Leadership
Under sprint pressure the reflex is to micromanage. But bad code is usually a symptom; you fix code with refactoring, you support engineers with communication.
Career & Seniority
Repeating year one five times isn’t five years of experience. Seniority is measured by problem scope, genuine ownership, and mentorship impact.
Teams & brands
A decade of building with teams that trusted the unglamorous parts of the job.
The tools
“One of the most dedicated and technically proficient backend engineers I’ve collaborated with. He consistently delivered clean, scalable and well-documented code.”
“He consistently demonstrates the ability to translate complex requirements into elegant solutions… his willingness to mentor junior team members has been instrumental in fostering a culture of continuous learning.”
