I lead engineering for a health and wellness platform I've built from the ground up, taking it from first commit to a live product on the App Store and Google Play. My work covers the full stack of decisions, not just the code: system architecture, choosing the right backend for the problem, data modelling, release management, and the long-term consequences of each of those choices. Running a product for six years means living with your own architecture, which changes how you design things. Day to day this involves Flutter across iOS and Android, backend and API design, third-party integrations, subscription infrastructure, analytics, and store compliance on both platforms. The reason this matters for client work: I've had to make the trade-offs that most developers only implement. When a client asks whether something is worth building, I've usually already answered that question for myself.

I build production mobile apps for clients across health, social, marketplace, video, and hardware-connected products. Everything ships to both the App Store and Google Play. Recent work includes an LED display controller communicating with hardware over a custom Bluetooth and WiFi protocol, a frame-accurate video timing app for sports coaches, a collectibles marketplace with a full admin panel, and an expense tracker using AI vision to extract structured data from receipts. I work as a technical partner rather than a task executor. That means scoping honestly, telling clients when an approach won't hold up, and handing over clean, documented code they can take anywhere.
