About Yahya

Hi and welcome to my profile!

My name is Yahya and I am a freelance Data Engineer with a passion for transforming complex data into clear and valuable insights. I have extensive practical experience with tools such as Snowflake, my favorite cloud data warehouse, Databricks and dbt, within both AWS and Azure environments. I am also Azure DP 203 certified and a member of the official Snowflake Squad, so you can trust that your data challenges are in good hands with me.

I get a lot of satisfaction from solving complex logic and designing and building robust data models from scratch. In recent years, I have had the opportunity to realize impactful solutions for organizations such as RFH, Buma Stemra, Athlon, and others. I also have extensive experience with SAP HANA, BODS, SQL Server, and Oracle, which allows me to quickly feel at home in diverse database environments.

My specialization lies in data migrations, where I breathe new life into existing and often outdated reports by transferring them to modern data platforms that are ready for the future. My approach is always focused on alignment and added value. A data architecture can be technically perfect, but ultimately it's about what it delivers for the organization. That's why I start by understanding the real needs of stakeholders and work according to an Agile approach. Start small, deliver value quickly, and continuously improve.

There is much more to tell, but I prefer to do that in a personal conversation. Are you curious how I can contribute to your next data challenge? Feel free to contact me, I'd be happy to think along with you.
