About me
How I can help
I work with product and engineering teams on backend platforms, cloud architecture, and data-intensive systems. That includes building new services, modernizing existing systems, and investigating performance, reliability, and cloud costs. I take work from requirements and design through implementation, release, and operation.
Recent consulting work includes an AI-powered cost model builder for Expana and an engineering workflow for Salesforce development at Salesfive, both via nexamind. I build the application and data foundations around the models, including retrieval, integration tests, prompt releases, and monitoring.
Java, Kotlin, and AWS are my core tools. Recent projects have also involved TypeScript, Azure, and Databricks. I choose the stack to fit the system and the team that will maintain it.
How I work
- Clarify the problem and agree on what a useful result looks like.
- Own the lifecycle: design → build → deploy → operate.
- Choose proven technology and keep the system understandable.
- Trace failures to their root cause and verify the fix.
- Compare approaches, document the trade-offs, and make a decision.

How I got here
I studied Computer Engineering in Cairo on a competitive scholarship and graduated with distinction. After working in startups, I joined Amazon in Edinburgh, working on Top-Level Domains and advertising analytics, then moved to Berlin for retail systems and AWS S3. In 2025, after more than nine years at Amazon, I started my own consultancy.
Journey
