I'm a software engineer based in Alexandria, Egypt, currently building at @specright. I gravitate toward problems where correctness, latency, and resource budgets actually matter — order books, storage engines, message queues, rate limiters, recovery tools.
I write a lot of Go for systems work, PHP / Laravel and TypeScript for the product surface, and reach for Python when a problem needs to be solved in an afternoon.
"Engineering background • Product & business curious • Trying to build things that work and matter."
- 💱 Fintech & financial systems — exchanges, matching engines, market data, post-trade
- 🌐 Distributed systems — gossip protocols, replication, queues, consensus
- 🗃️ Database internals — storage engines, B+ trees, WAL, binlog recovery
- 🔓 Open source — contributing where the work compounds for everyone
- 🤝 Volunteering — open to pro-bono engineering for OSS projects and mission-driven orgs
If you're building in fintech / financial infrastructure or running an OSS project that needs hands — let's talk.
