Senior🎓
Top SchoolArnaud Larroque is a Senior Data Specialist with 13 years of experience designing and optimizing large-scale data platforms, cloud migrations, and backend systems across energy, finance, retail and cybersecurity domains. He has a track record of shrinking query times by orders of magnitude, stabilizing Spark-based pipelines, and leading cross-border architecture initiatives that accelerate delivery. Comfortable as a hands-on architect and interim CTO, he has built production LLM-powered tools, bootstrapped an AI offering, and set up platforms and CI/CD to support teams of data engineers. Equally adept at mentoring engineers and conducting technical hiring, he frequently combines code-level troubleshooting with strategic platform design. Based in Lyon and trained at CPE Lyon, Arnaud brings a pragmatic blend of enterprise-grade rigor and startup agility that turns stalled AI or data proofs-of-concept into scalable production systems. An often-overlooked strength is his ability to decouple legacy systems via middleware patterns, reducing maintenance effort while enabling faster feature delivery.
