👤
Senior🎓
Top SchoolErwan Deruelle is a seasoned software engineer and staff-level technologist with 11 years of experience building distributed, event-driven systems across JVM and JavaScript ecosystems from Paris. He has led feature teams and technical initiatives at fintech Swan (BaaS) and core-banking startup Ditto, shipping production systems using Scala/Java, Node.js/TypeScript, Kafka, event sourcing and cloud-native platforms. His background includes deep search and analytics expertise from a long consultancy track record (Elasticsearch, Solr, ELK) for major enterprises like Canal+, Sephora and La Poste, which informs a strong operational mindset.

Notably, he pairs hands-on coding with technical leadership—shaping architectures, POCs and devops pipelines—rather than purely managerial work.
