Sheet 27

Building AI systems, full-stack products, and documenting everything I learn.

Hi, I'm Yashwanth — welcome to my space. I love to build stuff, and write about what I explore along the way. Hit me up if you want to connect.

Currently

  • Neural networks, from the math up
  • RAG & evaluation for Bloom IQ
  • Robotics, new territory
  • Go, for the parts TypeScript shouldn't do
  • Open to engineering roles
