Summary

Senior🎓
Top SchoolErwan Leboucher is a Senior Software Engineer based in Paris with 11 years' experience building high-performance backend and data systems primarily in Golang and Python. He has a track record of diagnosing platform-wide bottlenecks and scaling critical pipelines—reducing p95 latencies by a third, cutting logging costs by 96%, and making data pipelines 30x faster while slashing costs. At Wolt and BlaBlaCar he designed event-driven architectures and rebuilt bulk import and audience systems to handle 100x higher throughput with sub-10ms query responses for real-time features. He focuses on production-ready code that is well-tested, observable, and maintainable, and has repeatedly improved reliability through observability (OpenTelemetry, Prometheus) and end-to-end testing (Playwright). Comfortable across the stack with React/Vue frontends and cloud-native tooling (Kubernetes, Kafka, DynamoDB, PostgreSQL), he also mentors peers to help teams ship better software. An unusual strength is blending hands-on performance tuning with product-minded integrations that directly improve user and partner experience.
