About Cedric

🎯 Helping teams fix APIs latency, slow database queries, and cloud cost - with pragmatic solutions.

👇 What can I do:

→ Production profiling (CPU, RAM, I/O, databases)

→ Root-cause analysis of performance and stability issues

→ Shipping code and infrastructure changes

→ Database and query optimization

→ LLM and cloud cost optimization

→ Ongoing improvements to prevent regressions

👇 How I work:

→ I focus on the areas with the 80% most impact - not surface-level optimizations.

→ Then, I identify the primary sources of performance, stability or cost issues.

→ Next, I ship fixes directly, and provide proof of their effectiveness.

→ I work with your team in Slack, and handle issues end-to-end rather than handing off reports.
