Data Analytics & ML Full-Stack Web Dev Available for Freelance

BASED IN
BERLIN.

I'm a Data Analytics master's student at Berlin School of Business and Innovation (BSBI) with a serious obsession for turning messy datasets into actionable insights. I specialise in machine learning, EDA, and building data products that actually get used.

On a mission to understand why data behaves the way it does and to build systems so intuitive that even a non-technical stakeholder would be impressed. I also do full-stack web development — React, TypeScript, Vite and have shipped production websites with real users.

Currently hunting for a Werkstudent Data or Web role in Berlin where I can ship things that matter.

I also take on freelance projects from landing pages and corporate websites to data dashboards and full-stack web apps. If you need something built properly, on time, and without the agency markup, let's talk.
