Freelance Tech Lead Data Engineer in Paris, building reliable data platforms and distributed processing systems.

I have 7+ years of freelance experience across banking, real estate, and fintech. My work combines hands-on delivery, technical leadership, shared tooling, data quality, and performance engineering. Recent production work includes leading six Data Engineers and processing workloads around 100 million rows.

My strongest areas are Scala, Spark, Snowflake, Distributed Processing, and Performance Engineering. I also use Python in production.
