Leonidas Villeneuve
Senior Software Engineer at Tesorio
São Paulo, Brazil
Summary
🤩
RockstarLeonidas Villeneuve is a Senior Software Engineer based in São Paulo with 9 years of hands-on experience building and operating high-throughput, resilient backend systems across startups and large companies. He has led architecture and delivery for mission-critical projects—designing autoscaling warehouse and orchestration services, rebuilding checkout systems that cut p95 latencies dramatically, and driving multi-team handovers during corporate mergers. Comfortable in remote, async, cross-continental teams, he combines rapid incident triage (delivering emergency fixes in under 24 hours) with longer-term engineering improvements like transactional outbox and optimistic locking patterns. He pairs strong technical ownership with mentorship—regularly conducting code reviews, coaching engineers, and shaping developer experience initiatives. A founder-turned-senior engineer, he brings entrepreneurial grit and low-level ops experience (self-healing Ceph clusters, containerized infrastructure) that helps bridge product, reliability, and scalability in production systems.
