Shantanu Bal

Senior Software Engineer · Seattle → New York

10+ years building distributed, cloud-native systems at scale — most recently at Amazon and Axon. Now focused on applying that depth to financial technology.

Currently building Horizon, an AI-powered platform making financial market insights accessible to everyday investors — a direct expression of where I want the next chapter of my career to go.

My Journey So Far

I grew up in Chennai, South India, studied Computer Science there, and went on to earn a postgraduate diploma in management from IIM Ranchi and a Master's in Computer Science from USC in Los Angeles. I then spent nine years at Amazon — working across devices, Alexa, Prime Air, and Amazon Robotics — before joining Axon, where I've been building cloud infrastructure for vehicle intelligence. Now I'm drawn to the intersection of finance and technology, and building Horizon made that concrete. The next chapter is New York.
