Olivier Gaça
Staff Senior Software Engineer at Datadog
France
Summary
🤩
RockstarOlivier Gaça is a Staff Senior Software Engineer based in France with over a decade of deep C++ expertise and six years in leadership roles, currently shaping Datadog’s componentization and end-to-end testing frameworks. He blends low-level systems knowledge (Windows/Win32, multithreading, performance tuning) with higher-level C#/.NET and ASP.NET Core experience, and has improved throughput of a DogStatsD C# client fivefold through profiling and allocation reduction. Olivier leads cross-team initiatives and an international team, setting roadmaps, OKRs and hiring while maintaining high retention through a people-first approach. He is an active open-source maintainer—creator of OpenCppCoverage and contributor to prominent repos like DataDog/datadog-agent—demonstrating practical DevOps and Windows systems skills alongside backend engineering. Comfortable with large-code refactors and advanced C++ techniques (templates, ABI/calling conventions), he also experiments in Rust (including an AI for StarCraft II), showing curiosity across languages and domains.
