Summary
👤
Senior🎓
Top SchoolLoïc Wisniewski is a Senior Software Engineer with a decade of experience specializing in data engineering: building ETL pipelines, data platforms, schedulers, and job orchestration to move OLTP and event data into analytics-ready OLAP formats. He’s worked across teams at Zendesk and Datadog, designing SQL compilation engines, Spark/Hudi pipelines, and integrations with internal data platforms while keeping an eye on reliability and observability. A pragmatic “lazy” engineer, he automates repetitive work to boost team productivity and prefers elegant, global designs that simplify long-term maintenance. Based in Montpellier, France, he pairs strong academic training in mathematics and computer science with hands-on Scala, PostgreSQL, Redshift and orchestration experience, and a knack for stepping back to reframe solved problems for fresh improvements.
