Senior Backend Engineer - Database Architecture
Oregon, United States
Summary
👤
Senior🎓
Top SchoolLeonardo Da Rosa is a Senior Backend Engineer specializing in PostgreSQL performance and database architecture with nine years of experience designing scalable data systems for high-traffic platforms. At GitLab he architects sharding, partitioning, replication and zero-downtime upgrade tooling for a multi-tenant system serving millions, while running cross-team database triage and bake‑time validation against real production traffic. He pairs deep operational expertise—connection pooling, logical replication windows, query debugging—with developer enablement, creating frameworks that reduce technical debt and make large-scale Postgres safer for engineers and customers. Previous roles in payments and event-driven systems sharpened his distributed-systems instincts and humility working with legacy code. Currently pursuing a Master’s in Systems Engineering at Harvard Extension School, he focuses on the hard trade-offs between scale, reliability, and speed of change.
