Who is Nitish Kumar?

A Bit About Me

I'm a first-year B.Tech student in AI and Data Science at Jaipur, but for the past year I was the Operations and Systems Lead at an AI marketing agency, building real production systems for actual paying clients.

I have a brute-force mindset. I don't back down from complexity. GHL pipelines, Conversation AI bots, Voice AI agents, n8n automations, Supabase backends, custom web apps. I built all of it. Not tutorials. Actual client work.

My goal is to be the right hand to a founder or agency who needs someone to handle all the technical and operational side so they can focus on growth. Give me a problem, I'll figure it out.
