Back to original languageAbout Cyril
Yes, we love them and cherish them, our old technologies… but at some point, you have to know how to say goodbye to them. Because no, that good old VBA script that's been running since 2007 in a 25 MB Excel workbook is not an information system. It's a relic. And that's where I come in
I am a freelance specialist in data flow transformation and modernization, with a real passion for migrations. My playground: Python, Snowflake, Airflow, Pandas, SQL, Glue, Spark etc... in short, everything that helps you go from "we run this manually every Monday" to "it's automated, versioned, and monitored".
I have a strong taste for clear architectures, robust pipelines, clean and well-documented scripts. I like to understand the business behind the data, restructure, purify, automate. And above all: avoid production nightmares caused by a misplaced file or a forgotten macro.
Do you have a migration project, an automation need, a data flow that's running out of steam? Let's talk about it!
