CTO & Co-founder Β· 20+ years building software that matters Β· π§π· β πͺπΈ β π¨π
Co-founder & CTO of Upgrid β a Swiss energy marketplace that connects local solar producers directly with consumers. Guaranteed lower prices, 100% local renewable energy, zero hardware. We're reshaping how communities buy and sell electricity in Switzerland.
20+ years across the full spectrum β from IBM and GFT to N26 (one of Europe's largest fintechs) to Personio, and now leading my own company. I've been hands-on building 5+ international banks, scaled systems to millions of users, and led engineering teams through hypergrowth.
The through-line: solving hard problems at scale, in regulated industries, across borders.
Backend at heart β JVM, Kotlin, distributed systems, event-driven architecture (Kafka Summit speaker, not by accident). I've done mobile (Flutter), led platform teams, and shipped things people actually use. Also built and maintained an app with 2,500+ daily active users as a side project.
I've spoken at Kafka Summit London, KotlinConf, WeAreDevelopers World Congress, DevBCN, JavaCro, and gave a TEDx talk on AI back in 2019 β before it was cool. Happy to talk distributed systems, fintech lessons, energy tech, or honest career advice.
Born in SΓ£o Paulo π§π·, spent a decade in Barcelona πͺπΈ, now based in Basel π¨π. Fluent in Portuguese, Spanish, English, and Catalan.
