Mohamed Azahrioui
I build backend systems, AI-agent guardrails, RAG workflows, and cloud-connected tools with a focus on auditable logic and production behavior.
Recent work includes CodeHive's Azure RAG knowledge base, Kojac client products, ReachGate vulnerability triage, TrustGate runtime authorization, and production automation for external clients.

What I work on
Practical backend help for APIs, agent guardrails, RAG, and internal tools.
Automation tools
Python and Node workflows for exports, agent guardrails, RAG systems, cloud integrations, and repeatable operations.
Data workflows
PostgreSQL, SQLite, BigQuery, and Azure-backed systems that keep business rules explicit and production behavior predictable.
Selected work
Projects with backend substance.
A mix of AI security, runtime authorization, client automation, API design, realtime backend work, and algorithmic problem solving.

Available for work
Need a backend, RAG workflow, agent guardrail, or API integration built?
Send me the issue, workflow, or API idea. I can help shape it into a maintainable system with explicit business rules and auditable behavior.
