Abdulrahman Khalid
Senior backend engineer building high-throughput distributed systems — and the AI that runs on top of them.
5 years shipping production systems in Go, TypeScript and Python. Lately: LLM agents, RAG pipelines and observability at scale. Currently a Senior Backend Engineer at Soum, Saudi Arabia's leading recommerce marketplace.
About
I build the parts of software that have to stay up: high-throughput, low-latency services in microservice environments. I've owned mission-critical systems, led incident root-cause work, and scaled backends through 10x growth — most often in Go, TypeScript/Node and Python.
Recently I've been shipping AI into real production workflows: LLM agents, RAG pipelines on Qdrant and pgvector, multi-LLM serving, and the Model Context Protocol. I like the messy seam where distributed systems meet applied AI.
