GetGround

GetGround

Multi-tenant, white-label building management platform used by multiple enterprise operators. I owned core architecture and features across mobile, web, and backend over 6+ years — shipping, scaling, and maintaining a long-lived production system as its sole platform engineer since 2025.

TYLS

TYLS

Fiscal platform for French furnished-rental landlords, built from the ground up and taken to launch in three months. I designed the architecture and the engineering system around it — then audited every change merged during a three-week absence and used the findings to harden that system.

Took ownership of a Flutter mobile app suffering from severe stability issues and client distrust. Stabilized the platform, delivered critical features under tight deadlines, and restored technical reliability and client confidence.

Richemont

Richemont

Two consecutive engagements at Richemont. First: joined as iOS developer, learned Swift under pressure, matched team output within weeks. Second: redesigned the feature flag system across 14 maisons, wrote the supporting tooling, and took sole ownership of the eCard web app.

Adopt

Adopt

Joined a severely delayed project and led development of Adopt's B2B management system, replacing fragile Excel-based workflows with a scalable Commercetools + Next.js solution. Delivered on time despite the late start.

Wojo

Wojo

Led the mobile migration during Wojo's separation from the GetGround platform. Started as mobile-focused, then expanded to support web delivery under Covid-era pressure — evolving into full-stack ownership through necessity and delivery.
