Rockstar🎓
Top SchoolAlessio Placitelli is a Data Engineering Manager at Mozilla with 15 years of experience building robust data and mobile systems and leading engineering teams. He moved up from hands-on data engineering to management while continuing to contribute code, notably implementing a thread-safe events storage engine and telemetry APIs for Firefox for Android (Fenix/ Glean). Comfortable across backend, mobile, and ML-adjacent work, he has shipped Android telemetry integrations, WASM bindings for speech-to-text, and database refactors with strong test coverage. Based in Rome, he pairs practical implementation skills with research experience from Microsoft and ICAR-CNR and a Certificate in Data Science from Harvard Extension School. Colleagues know him as a curious, fast-learning engineer who bridges product telemetry, data infrastructure, and developer-facing libraries. He brings a rare mix of shipping critical open-source contributions in high-profile projects and managing data teams at scale.
