Donga Kasi Pavan Kumar
こんにちは👋 I'm Kasi — a software engineer who builds web and mobile products that keep working as they grow: simple, reliable, and built to last.
Previously, I was Lead Software Engineer at Swadesh (YC S19), where I led Swadesh GlobalPay, a cross-border remittance platform between India and the US, end to end. See my work for more.
More about me
I write about complex concepts, the universe, and the joys and frustrations of code — on my blog, Quora, Stack Overflow, and Medium.
Away from code, I'm usually outside staring at the stars. That curiosity led to Cosmicode, a weekly newsletter on the mysteries of the universe. Favorite star? Betelgeuse — partly for the name, partly because it might one day explode in a show that would make New Year's jealous.
Back in 2018, my buddy Surya Madhavan and I started CloudTechy to review gadgets and geek out over hardware. It's quiet these days, but worth a stroll if you're feeling nostalgic.
