About
“I like to build communities to share products”
Owais Korejo
CS & Business @ TCD · Dublin
The short version
I'm Owais, a 19-year-old CS & Business student at Trinity College Dublin. I've been programming since I was 9 and building businesses since I was 15. I love the deterministic nature of code — if something's broken, there's always a reason.
Alongside engineering, I'm deeply into entrepreneurship: I ran an e-commerce store that hit $110k in sales, and I've since built and launched Groooves, a music-reviewing app on the App Store. One thing that sets me apart: I focus heavily on marketing before a product ships. When Groooves launched, 200 users signed up in the first week — we've since hit 15K+ users and 200 million social media views.
