MarsleyMash
Founder running multiple ventures from Nairobi — edtech, fintech, e-commerce, and SaaS. I don't just build websites. I build businesses.
I'm Mash. Twenty years old, building from Nairobi. I have products deployed across edtech, e-commerce, SaaS, and fintech — and I run electronics operations at Munchify Market. My build layer is Cursor, Claude, and Antigravity. I ship, deploy, and iterate. I'm still early. But I'm moving, and I'm not stopping.
