About Nirmata

Hi, I'm Rishav Kumar

I build applied AI/ML projects to solve real problems, from early experiments to production systems.

This site is where I showcase what I build and write about the work behind it: the problem, the approach, what worked, what didn't, and what I learned along the way. I also share deeper notes on the ideas and tools I had to understand to solve each problem.

I built lead-propensity models to reduce outreach costs and improve the efficiency of counselling teams. I'm currently working on post-training text-to-speech (TTS) models.
