Summary
Roger Tan is a Senior iOS Engineer based in London with over a decade of hands-on experience building mobile apps across startups and enterprises. He’s shipped consumer-facing products that earned multiple "Best New App" and App Store homepage features (notably with Sup and OptiMiam) and led major launches like Costa Coffee’s loyalty, Pay & Collect, and Costa Express features. Comfortable across the mobile stack, he has migrated large codebases from Objective-C to Swift, implemented real-time features and robust testing, and dabbles in Android development as well. Educated at EPITECH with a digital innovation certificate from HEC Paris, he blends strong engineering craft with product-minded thinking. Though London-based and actively contributing at firms like Valtech and Kin + Carta, he prefers not to be approached for roles in France.
