I’m a builder at heart.

I’ve spent most of my career at Microsoft, but my path started in Egypt—first at ITWorx, then at a startup called Technivance, where I got my first real taste of building products and shipping software that people actually use. That mix of structured engineering and startup chaos stuck with me.

I later joined Microsoft Advanced Technology Labs in Cairo, working on Bing for Arabic markets. From there, I moved across teams inside Microsoft, including Bing Search and Microsoft Translator, learning how large systems evolve and how small decisions can have massive impact at scale.

While working at Microsoft Egypt, I co-founded and built luis.ai, a machine teaching and active learning project. I later moved to the United States to continue working on luis.ai, collaborating more closely with teams and scaling the project further. After that, I joined the Speech Services team, where I worked on building and operating large-scale AI systems.

That work gradually evolved into building Azure OpenAI infrastructure, and more recently into Microsoft’s AI training infrastructure, supporting large-scale model training and production workloads. Over time, my role grew from writing code to owning systems, helping teams navigate ambiguity, and mentoring other engineers.

Outside of work, I’ve always enjoyed building things end to end—code, hardware, and ideas—including a 3D printer I built from scratch. I love side projects, open source, and the process of learning something new and seeing where it leads.

One of those experiments, Vagrant-Parallels, ended up being adopted by Parallels Inc., which was a great reminder that small ideas can go further than you expect.

I’ve also tried my hand at startups—some failed, some taught me a lot, and a few are still evolving. Projects like el7a2.net, Groupinion, and UserTalk came from a simple desire to build useful products and learn by doing.

What motivates me most is building meaningful systems, working with thoughtful people, and solving problems that don’t have obvious answers. I care deeply about quality, clarity, and leaving things better than I found them.

If any of this resonates, feel free to leave me a message.
