Intended Side Effects
Data always tells a story —but not always the full one.
I help you uncover what's missing, and create narratives that hold space for diverse perspectives, and meaningful connections.
👋 Hi, I'm Janina,
a data scientist, designer, and visual storyteller.
Data is never neutral. Especially when it touches lives, land, and histories that don't fit neatly into metrics. I help turn complex data, often shaped by power dynamics, into visual stories that question and foster accountability.
My background in fashion and sustainability taught me firsthand the limitations of impact within extractive models. Today, I use data to challenge those very frameworks, bringing to light the (more-than-)human stories that are often erased.
I also mentor emerging data scientists in Python, SQL, machine learning, and storytelling, aiming to equip them with the technical tools, critical awareness and narrative skills needed to make impact. This work is integral to my own (un)learning, reflecting on hierarchies, collective knowledge, and non-linear growth.
I'm available for freelance projects, collaborations, and am keen to take on volunteer initiatives to create something meaningful.
Let’s connect! ✨
