Hi, I’m Solomon:

AI Developer and Workflow Architect.

I build intelligent, production-ready systems that think, retrieve, and act. My focus is on modular agents, RAG pipelines, and scalable data workflows for real-world deployment. I specialize in agentic architectures that integrate APIs, vector search, and semantic memory, designed for clarity and scale.
