Software Engineer · CTO
🇪🇬 Cairo, Egypt
Where product ambition meets technical reality.
Software engineer across the whole stack: backend, frontend, mobile, and the infrastructure underneath. I also lead the teams that keep it running. 8+ years in technology leadership, most of it spent making trade-offs explicit, keeping systems boring, and shipping only what's actually needed.
| What I do | |
|---|---|
| 🏗️ | Systems & architecture boundaries, queues, event flow, data modeling |
| ☁️ | Infra & ops self-hosting, observability, reliability, cost that doesn't surprise you |
| 🤖 | AI in practice LLM apps, RAG, agents, automation that fails safely |
| 🔐 | Security & identity authN/authZ, SSO, multi-tenancy |
| 🧭 | Leadership architecture reviews, mentoring, technical strategy |
- 🔨 Building and maintaining open source, and shipping products end to end
- 🧪 Taking new tools from experiment to production, where reliability matters more than cleverness
- 🌱 Learning something new every quarter, and unlearning what stopped being true
- ✍️ Writing at kayed.dev about architecture, operations, and responsible AI
- 💬 Happy to talk about system design, self-hosting, and scaling teams
