I've spent five years taking software from architecture to production across web, mobile, backend and cloud. Lately that means a native iOS app for bol.com sellers, a monolith-to-microservices migration, and an AI goal planner I designed, built and launched on my own.
I like small, verified steps: ship progressively, run things in shadow mode, and move on only when the data matches. I use AI every day, but anything that touches business logic or production data stays a human decision.
| 📱 Zoloo (formerly Boloo) | Senior Software Engineer (Mobile & Full-Stack). I own the native iOS app (Swift/SwiftUI, with passkey sign-in, sales dashboards and an AI assistant) and lead the move of core domains from a monolith to Python/FastAPI microservices, including 40M+ records migrated with zero data loss. → Read the case study |
| 🧩 Syncflow | An AI goal planner that turns any goal into small, time-estimated steps and hands them to you one at a time. Web and native iOS, built solo, 1,200+ users. Includes Autopilot, an agent that always asks before finishing anything. → Get the iOS app · How I built Autopilot |
