Writing
I write on Medium about the systems I ship: tool-calling and the Model Context Protocol, gateway and Kubernetes work, and access control. The pieces below are the ones worth reading first.
Practical deep-dive on retrofitting existing microservices to expose MCP endpoints — drawn from the production AI Agent Platform at Careem (~200K req/day, ~800 tools, ~60 agents).
A primer on what MCP is and why tool-calling matters for production LLM systems — published before MCP became mainstream.
Token authentication, authentication flows, role-based access control, and Kubernetes integration. Backs the ArgoCD + Keycloak GitOps work at Intech.
