Luca Bello

Technical lead of the Observability team and interim manager of the Tracing and profiling subteam. Defines the team's technical direction, priorities and roadmap.

• LTS release: owned the first LTS release of COS and COS Lite from scoping through delivery, spanning four months, 884 pull requests and 8 stakeholders from other departments.
• Roadmap planning: led the team's roadmap planning and presented it to senior management, introducing a new planning process based on individual research and demos; provided weekly one-on-one mentoring across the team.
• External impact: led the team's engagement with OWASP, resulting in a citation in the OWASP Logging Vocabulary cheat sheet; co-authored the Juju page in the upstream Mimir docs.

• Ownership: took projects from idea to delivery (e.g. load testing), mentored juniors and moderated all team meetings.
• Delivery: delivered over 50% of a 5-person team's work, completing 250% more planned days per sprint than peers.
• Security: drove CVE scanning and SSDLC, and spearheaded company vulnerability response guidelines.

• Supply chain: led packaging of upstream Observability software as rocks (minimal, reproducible, patched images).
• CI/CD: single-handedly built department-wide automations that set new quality standards.
• Testing: redesigned testing with feature-first semantics and parallelization, 225% faster suites.

Part of the CERN IT Monitoring team, operating both internally over CERN's data center operations and externally over the WLCG (Worldwide LHC Computing Grid), with Agile and DevOps methodologies.

I focused on designing, developing and maintaining a large-scale high-availability infrastructure which handled the entire monitoring data pipeline to provide Observability to CERN's operations.
