Don't take my word for it. Take theirs.

Situation

One of Europe's largest banks needed a new payment feature in its live iOS app — configurable per country, open to further features, identical to Android — built by a small team without stopping releases.

What I did

Owned the iOS side end to end: designed the module to be reused across markets and plugged into the app's architecture, then built 2 iterations in Swift — SwiftUI, Concurrency, Observation — covering onboarding, profile and the payment-card lifecycle. Agreed the architecture with the Android and BFF engineers so each rule lives once, in the right layer, and raised the iOS chapter's bar on SwiftUI adoption, UIKit–SwiftUI interoperability and documentation.

Outcome

Module released, on schedule

1

Iterations shipped, each a distinct experience

Countries: Belgium and Italy

Situation

Tessa, a Unilever-backed start-up, had a React Native app and 4 developers with little native experience. The roadmap needed payments, push, deep links and analytics done natively — and then a second app, from hackathon idea to MVP, in 6 weeks.

What I did

Led the team as lead mobile developer. Built the native iOS and Android components and their React Native bridges — Adyen payments, Firebase push and deep linking, Segment and Mixpanel analytics — and owned CI/CD and store delivery with GitLab and Fastlane. For the MVP I chose the stack, set up stores and pipelines, built the core feature and coached the 4 developers into native work, with pairing, reviews and tests as the normal way of shipping.

Outcome

Engineers led, and coached in native

4

Native SDKs bridged into React Native

5

Weeks from hackathon to MVP

Situation

KLM's enterprise iPad app for Passenger Operations — the tool ground crews at 180 airports use to board, rebook and assist passengers — needed a lead to ship features every sprint while moving a decade of Objective-C to Swift.

What I did

Led the team of 4 for two years as lead iOS developer. Shipped 14 features with business, data, design and QA — from boarding and baggage search to last-call messaging and a point of sale with Adyen — and owned the shared iOS frameworks every KLM enterprise app is built on. Co-led the migration of 200,000+ lines of Objective-C to Swift 2 in 3 weeks, half the estimate, then Swift 2 to 4; and made standards, pairing, reviews and unit tests the team's default while coaching juniors and interns.

Outcome

Engineers led, requirements to release

4

Features shipped to crews at 180 airports

14

Lines moved from Objective-C to Swift, in half the estimated time
