I design & build web, mobile & embedded systems that actually ship.
Kawkaby is the one-engineer studio of Tamer Yousri — a full-stack developer and hardware engineer based in Cairo, with 15+ years building LMS platforms, educational hardware and custom software for clients across the UAE & MENA. Web, mobile, electronics and 3D printing: one pair of hands, from first sketch to working prototype.

01 · What I do
Five disciplines. One engineer.
Most products need a web app, a mobile app and a box of electronics that all talk to each other. Instead of managing three teams, you work with one engineer who covers the whole orbit.
EdTech
E-Learning & LMS Platforms
Full-stack learning platforms for governments and schools — competition workflows, SCORM content, analytics dashboards and AI-powered student assistants.
Mobile
iOS & Android Apps
Companion apps for your systems: open doors, watch sensors, receive alerts and manage your data from anywhere.
Electronics
Electronics & Control Systems
Access control, laser perimeter security, medical pump control, incubators, sensor interfaces — from PCB design to firmware.
3D
3D Modeling & Printing
CAD design and FDM 3D printing for enclosures, mechanical parts and presentation-ready prototypes.
02 · Selected work
Real hardware. Real software. Shipped.
A few of the systems I’ve designed and built — from medical devices to villa security, each one taken from idea to a working product.

03 · How I work
From rough idea to working prototype.
No handovers between hardware and software teams, no lost-in-translation specs. The person who solders the board also writes the app.
- 01
Understand
You bring a rough idea — “control this hardware from an app” or “manage this process”. Together we clarify the problem and what “done” looks like.
- 02
Design
One coherent system across hardware and software: schematics, data models and UI flows that are built to talk to each other.
- 03
Build
Electronics, firmware, web and mobile — developed in tight loops, with working demos you can hold and try.
- 04
Ship
A real, testable prototype in your hands — then iteration, documentation and support once it meets the real world.
04 · Toolbox
Chosen per project, not by habit.
Tools follow the problem — but these are the ones that have earned a permanent place on my bench.
