What I'm looking for

I’m looking for a senior or lead iOS role in Barcelona, where I can bring what I’ve built at a small startup to a European product market.

At eSimpliﬁed, I built the KnowRoaming iOS and Android apps end to end, from architecture and SDKs through payments, analytics, and store releases. The apps support 16 languages and have more than 120K installs.

I rebuilt both apps from a legacy codebase into a modular, testable architecture, then carried a product redesign from Figma to release. I also made the apps white-label, so one codebase ships KnowRoaming and oSIM.

I designed, built, and published the company’s eSIM SDKs from scratch for use by our apps and partners. I own the mobile data layer, including eSIM provisioning, checkout, top-ups, verification, and token refresh.

At Tracker South Africa, I shipped consumer iOS features and built real-time vehicle tracking and alert screens, tuning map performance and battery use. I love the craft of iOS and care about clean, well-tested code and sensible architecture; I’m looking for a senior or lead iOS role in Barcelona.
