I built PropStack, a multi-tenant real estate SaaS, with role-based access for platform and tenant users. PostgreSQL row-level security isolates agency data, and a database trigger protects an agency’s last super admin.

For Shop PWA, I created an offline-first price checker and inventory app. Workers can look up prices and record sales offline, with queued changes syncing to Supabase when the app is online.

I built FlowConnect to connect M-Pesa payments with WiFi hotspot access. Its payment callbacks are idempotent, and successful payments create and expire customer sessions on a MikroTik router.

Through freelance web development, I built a dental clinic demo site and ClientQuest, a React and Supabase CRM for tracking outreach. I also wrote a load balancer in Go as my first systems project.
