Senior Backend & AI Engineer
I build the backend systems behind a 10M+ subscriber telecom — and I build them AI-native, with Claude Code, Gemini, and Codex in the loop.
01Profile
Six years of backend systems across telecom and fintech — microservices, event-driven pipelines, and PostgreSQL at scale for a 10M+ subscriber base. I work AI-native: orchestrating multi-agent workflows with Claude Code, Gemini, and Codex, and shipping LLM pipelines to production.

04 disciplines
Claude Code, Gemini, and Codex are part of the daily toolchain — from agentic development loops to LLM pipelines running in production.
Flagship discipline
01
Claude Code is my daily driver — not autocomplete, an engineering loop. I design and run multi-agent workflows: orchestrating fleets of agents in parallel, managing their context windows, and shipping production features with AI in the loop from plan to verified deploy.
Discipline
02
Shipped an Arabic real-estate search pipeline: LLMs turn free-text listings into clean, searchable records. Works with any model provider — Gemini by default, local Ollama as fallback.
Discipline
03
Different models for different jobs: cross-checking plans, parallel implementation tracks, and model-vs-model review before anything merges. The tooling changes monthly — the discipline doesn't.
Discipline
04
The 10M-record NoSQL-to-PostgreSQL migration ran with agent-written reconciliation scripts and continuous verification — AI accelerated the work, the zero-data-loss guarantee stayed on me.
03Impact

Records migrated

Note
Depth over breadth. Python/FastAPI and Node/TypeScript are where I live day to day, PostgreSQL is the piece I have taken furthest, and Go is what I reach for when throughput is the constraint.
