Full-Stack & GenAI Engineer

Hi, I'm Arpit Kumar Singh, a full-stack & GenAI engineer and a proud graduate of IIITDM Kancheepuram, Chennai, based in 🇮🇳 India.

I build end-to-end products that scale and ship on time. From RAG pipelines to production web platforms, I craft systems that just work.

You can reach me on 𝕏 DMs or Email.
