Parth Sareen
I work on Ollama and lead the agent tooling around it.
On the side, I build small tools for myself to experiment and push agents to their limits. Before that, I built a startup on agent reliability and worked at Apple, Tesla, and more.
Outside of that: latte art, Muay Thai, and writing down ideas as they form.
