Hi, I am Henrike

I believe good ideas and technology can change our reality. Today I am a Data Engineer I at Appmax, where I build ETL pipelines that serve as the foundation for analytics and data models.

About me

A career in data, a passion for building.

It all started at Instituto da Oportunidade Social (IOS), where I took the Full Stack Web Development course. Without it, I would not be where I am. From there, the path went through technical support, a Salesforce internship and the 2024 Geração Caldeira Python track, until I found in data the place where I want to grow. Along the way, I keep volunteering at the programming group of NGO COMQ.

I love music, photography, programming and art. They make me look at life with an extra layer. I carry the pillars of jiu-jitsu my father taught me: discipline, resilience and persistence applied to every area. I do not settle for standing still — I want to add value wherever I am.
