Top SchoolAlexis Destrez is a Senior Backend Engineer with 11 years of experience, based in Paris, who specializes in resilient, high-throughput backend systems and is a passionate Golang practitioner. At leboncoin he has driven mission-critical transaction scaling from hundreds weekly to peaks near a million, built task orchestration patterns for reliability, and led a company-wide OpenTelemetry migration to standardize observability. As Backend Guild Lead he scaled a community from ~50 to ~120 engineers, instituted governance and DORA-style operational metrics, and coordinated multi-country platform convergence in English.
