Summary
👤
Senior🎓
Top SchoolDagnogo Jean-francois is a Senior Android Tech Lead with roughly a decade of experience delivering high-traffic consumer apps across retail and e‑commerce, currently leading a 4‑person Android team at Carrefour from Greece. He has driven end-to-end features like product search, discovery, and shopping cart, shipped a production-ready Compose app, and previously helped scale Kaufland’s app used by 500k+ daily users. Comfortable across MVVM, Kotlin Flow, Clean Architecture and CI pipelines, he pairs hands‑on implementation with mentoring — onboarding juniors and performing technical interviewing. His background includes performance, caching and A/B testing improvements that raised crash-free rates and test coverage to parity or better with iOS. A former OpenClassrooms mentor and frequent freelancer, he blends engineering rigor from telecom/medical projects with product-focused e‑commerce delivery. He often surfaces non-obvious wins: improving offline behavior and introducing the company’s first A/B test to accelerate data‑driven UX decisions.
