Hi, I am Thevie

Thevie Mortiniera

Head of Data Operations & Customer Insights at Biostarks

I have spent over four years working in Data Science, evolving into a role that bridges data strategy, AI-driven automation and digital transformation. My journey has taken me across industries, from luxury goods to biotechnology, from pure software development to data operations and AI integration, helping businesses make smarter, data-driven decisions.
What I love about Data Science is the constant opportunity to ask why and find clear, actionable answers through data. Whether it’s optimizing processes, building AI-powered tools or structuring large-scale data platforms, I enjoy transforming complexity into meaningful insights.

I am fond of open-source projects & communities like Hugging Face, Stack Overflow and Kaggle, as I believe they have made programming and AI more accessible. I advocate for fostering innovation through shared knowledge, which empowers individuals to separate real insights from misinformation and leverage data responsibly.
I am particularly interested in how emerging technologies like AI, cloud computing and decentralized systems are reshaping industries. A key focus of mine is ensuring these advancements remain fair, ethical, and sustainable while being accessible to a wider audience.

Outside work, I enjoy playing and watching football—not just for the game itself, but for how it brings people together, even if just for a short moment.
