Fractional CTO for Generative AI! Former Founder/CTO @ MightySignal (acquired by Instacart), Director of Growth Engineering @ Instacart, and iPhone Engineer @ Apple.

I'm an exited Technical Founder & Operator with an extremely versatile skill set and track record of success! I'm currently most passionate about applied Generative AI and am able to supplement that interest with strong skills in Full-Stack Software Engineering, Growth, Recruiting, and Leadership.


I've founded my own successful startups, doubled customer acquisition efficiency at Instacart, and shipped 150M iPhones/iPads at Apple. In doing so, I've always built elite teams and have pushed the boundaries of engineering innovation!

Testimonials

  • I reported to Jason at Instacart for 1 year and he was a true mentor, guide and support to me throughout. He is creative, passionate, an excellent orator/presenter and problem-solver - all of which make him a great asset to the company. His honest, straightforward and most importantly, open approach with his team always instilled confidence and trust in him as our lead. I highly recommend Jason and would love to work with him again!

  • Jason is one of the smartest guys i worked with at Apple. He had strong technical skills and what impressed me the most was his eagerness to learn and get things done in a timely manner. He has introduced lot of good coding practices to other senior members of the team. He worked very well with other cross functional teams and also managed the CM very well. I wish Jason all the best in future and would strongly recommend him.
