Senior🎓
Top SchoolGaëtan Zoritchak is a Technical Architect and founder with 14+ years of experience building data platforms, full‑stack Kotlin Multiplatform solutions, and visualization tooling from Geneva. He currently leads Data Platform architecture at H&M while running Data2Viz, a project he founded to visualize data and push Kotlin adoption across mobile, web, and backend. Known for pragmatic performance work, he replaced a Beam ingestion with a Kotlin/Coroutine pipeline at Richemont, cutting processing time tenfold and implementing cost-tracking and DBT best practices. A frequent international speaker (KotlinConf, DevoxxFR, Kotlin Everywhere), he blends hands‑on coding, developer coaching, and architectural design. His formal studies include machine learning and functional programming, reflecting a continual focus on algorithmic rigor and practical data engineering. Colleagues describe him as an early Kotlin adopter who turns visualization ambitions into production-grade systems.
