People I’ve built with.
I've had the pleasure of working with Subhankar for over six years, during which he played a pivotal role in building our first startup product. His exceptional engineering skills and dedication helped us scale to over 15,000 customers and secure more than $2M in funding.

I build like it’s my own startup.
I’m a CTO and a co-founder myself, so I think in runway and trade-offs, not just tickets.
