About

Hey, Iโ€™m Rajat ๐Ÿ‘‹

Rajat Kumar

Engineer. Creator. Founder. Dad.

20 years building teams, organizations, and software products.

What I Do Now

I help organizations build great software at scale. My work spans:

The Journey

Leadership

Iโ€™ve led engineering organizations as Senior Director and Head of Engineeringโ€”first at a high-velocity e-commerce company focused on acquisitions, then at a growing professional services firm driving AI-powered transformation. These roles taught me how to align teams around metrics, mentor engineers, and translate business context into technical decisions.

Founder Life

I co-founded Shaztra, where we built AI-driven testing tools that let teams automate complex UI workflows using natural languageโ€”no scripting required. We even got a patent out of it.

Shaztra taught me everything about what not to do as an engineering-minded founder. Business, people, fundraising, salesโ€”I could write a book. The hardest lessons are the ones you donโ€™t learn in code.

Before Shaztra, I co-founded AppInitio (2012-2013), my first taste of startup life.

Netflix

The best engineering gig of my life.

At Netflix (2016-2021), I worked on the TV App team building:

Netflix showed me firsthand why talent density matters. When everyone around you is exceptional, you level up faster than you thought possible.

Earlier Career

Before Netflix, I spent nearly a decade across enterprise and startup worlds:

Talks

Iโ€™ve spoken at conferences about JavaScript modules, dynamic bundling, and conditional modules:
