• Database Systems
• Query Optimization

Grenoble, Auvergne-Rhone-Alpes, France

• Led and contributed to query planning and optimization work for Yellowbrick's analytical database engine.
• Focused on SQL optimization, execution planning, and optimizer improvements such as join elimination.
• Worked on rule design and planner behavior analysis for complex analytical workloads.
• Contributed to making optimization decisions more robust across workload classes, not only query microbenchmarks.

London, United Kingdom

• Worked on the query planner and optimizer of Yellowbrick's analytical database engine.
• Contributed to SQL optimization and execution planning improvements, including optimizer techniques such as join elimination.
• Debugged planner behavior when runtime execution diverged from expected cost assumptions.
• Improved plan quality for join-heavy analytical workloads.
