## About

```text
I've built production mobile products for Phundit, Bubbles, Accede, and Sibyl Systems, spanning fintech, logistics, on-demand laundry, and utility platforms.

At Phundit, I built the mobile product from scratch and helped scale it to 5K+ active users, shipping investment features, MTN MoMo payments, auto-deposits, KYC verification, and brokerage integrations. I also built engagement features that increased user engagement and deposit frequency by more than 30%.

I work primarily in Flutter and Dart, with full-stack experience across Node.js, TypeScript, PostgreSQL, Firebase, React, and Next.js. I’ve also delivered end-to-end products independently, including a retail POS system and a waste-management app.
