Koshy John (PERSONAL WEBSITE)

I build large-scale distributed systems and lead engineering teams that ship dependable software running on and over tens of millions of machines worldwide. My work centers on security, reliability, and removing operational friction for the world's largest cloud enterprises. I’ve also created apps downloaded tens of millions of times because I enjoy solving practical problems cleanly and simply.

I’ve spent more than a decade in Microsoft Azure, leading teams that deliver industry-defining platform capabilities showcased at major conferences and covered across the tech press. I’ve interviewed and mentored hundreds of engineers at Microsoft and have been consistently rated as one of the top mentors in Azure Core, where I also serve as one of five Mentoring Ring leads supporting the 10,000+ person organization globally.

Giving back to the world is particularly important to me, with consistent involvement in the Microsoft Give campaigns, including leading it for Azure Core in 2019 - resulting in the record levels of organizational engagement.

For Windows users, this site hosts several of the world’s leading software in their categories — built with the same principles & pride in craftsmanship I bring to my engineering work.

But... who am I?

If you really want to know, here's the TL;DR:

Family: I’m dad to a little boy – the center and joy of my wife’s and my world. My wife and I have built our life in Redmond, WA, and I try to show up as the better half every day. I’m deeply grateful to my parents, whose sacrifices set the foundation for everything I’ve been able to do and how I do it. My younger brother lives in New York City and works in one of the major management consultancies.

Heritage: I’m an American by choice and an Indian by birth – educated in India, New Zealand and the Middle East – a product & beneficiary of diverse and great nations that nurtured me at different stages of my life and indelibly contributed to who and where I am today. Each place left its mark on who I am and how I think. My wife is of Southeast Asian origin, and with our son we’re a pretty typical example of America’s mix of cultures.

Passions: Technology, of course. Growing people. Growing myself. Giving back. Cars - I have high-performance driver education, daily an enthusiast-known G82 and am a life-time member of the BMW CCA. I care about being the change I want to see in the world. And when I unwind, I'm into FPS games (Call of Duty) and classic city-builders (Pharaoh both 1999 & 2023 versions).

Thank you if you've read this far. I hope you enjoy everything this site has to offer.
