I'm Mash. I build products, run them, and figure it out as I go.
No CS degree. No co-founder (mostly). Just a guy who got tired of waiting for the right conditions and started shipping.
My stack isn't traditional — I use Cursor, Claude, and Antigravity as my main build layer. Not because I can't code, but because leverage matters more than purity. I move fast, I break things, I fix them, and I deploy.
Right now I'm running ventures across edtech, fintech, e-commerce, and B2B SaaS simultaneously. Some are making money. Some are close. All of them are real.
- Making Edyfra the tutoring platform students actually open instead of googling
- Scaling Mash Payments — shareable M-Pesa links for every Instagram seller tired of sending their number in DMs
- Keeping Cyzora profitable enough to fund everything else
- Figuring out where AI-assisted building actually breaks down — and what to do when it does
+ M-Pesa Daraja API · Paystack · Stream Chat & Video · Prisma · Resend · Upstash Redis
Pre-deploy quality gate for AI-assisted builders. Because vibe coders ship exposed RLS and leaked API keys more than they think.
