About
Building Software With Purpose
I'm Ajay Verma, a Python Backend & AI Developer with 4 years of experience building production-grade applications.
My work spans backend development, REST APIs, databases and asynchronous processing — through to AI integrations, RAG systems, LLM workflows, automation and production deployment.
I care about software that holds up in the real world: clear architecture, clean APIs, sensible data models, and AI that actually earns its place in the product. If you have a problem worth solving, I'd like to hear about it.
