I'm a backend and infrastructure engineer who designs, builds, and deploys distributed systems, mostly in Go, with Kubernetes, Helm, and Terraform. I've been shipping software for clients since 2018 and am comfortable owning a service from API design through CI/CD and production deployment.

In 2025 I designed the architecture of a 14-service enterprise system (ERP, CRM, document management) for a German software company and led initial development with a team of 6. I wrote the Protocol Buffers contracts, documented cross-service call order and failure recovery, and wrote the Terraform and Helm setup to deploy on Kubernetes.

I also open-sourced Cartwright, a saga-based distributed checkout system in Go, C#, and Python. It uses compensating transactions, a transactional outbox over NATS JetStream, and idempotency keys, and a scripted chaos test confirms there is no double charge when the billing service is killed mid-request. My other project, AxiomGraph, is a hybrid graph-vector database in C++17 with a Python SDK.

Since 2022 I've been the backend developer and Linux server administrator for Attila Gaming, a Minecraft network with 500+ concurrent players. I built matchmaking, instance lifecycle, and anti-cheat features across 15+ Java plugins, and reduced crashes by 60% and response times by 40%. I'm also contributing an out-of-bounds memory fix to llama.cpp's RPC server (PR open).

I'm a final-year Computer Science student (GPA 3.92/4.0, Dean's List), based in Cairo (UTC+2/+3), available full-time, and able to overlap with EU/US hours.
