Abhilash Thulaseedharan

Founder

As a coder by chance and an entrepreneur by choice, I love to design systems which is to make an impact on the people around me. 15 years of experience in enterprise product development, leading the development of mission-critical systems like flight operations and cargo handling for one of the biggest airlines in the world, where downtime of even a minute meant grounded flights and millions of dollars in loss. Cycling, running and working out keep me sane.
