Hi, my name is

Vikram Kumar Singh

I build

I'm a Backend Software Engineer with 6+ years of experience turning complex requirements into fast, reliable systems — from REST APIs and microservices to cloud-native deployments on Microsoft Azure, built with Python, Django, FastAPI, and Flask. These days I'm focused on applied AI: wiring LLMs like Azure OpenAI, Gemini, and LLaMA into RAG pipelines that power production-grade educational and gamification platforms used by real students every day.
