My passion for photography and storytelling has led me to a career as a photographer/photojournalist, collaborating with various international news agencies (partners: Snapshot-Photography, SZ-Foto, Ullstein, Imago etc).
Technical Skills & App Development: I completed a one-year vocational training in app development. My technical expertise spans native mobile development with Swift (SwiftUI) and Kotlin, as well as Flutter. Since late 2022 I have published four apps on the Apple App Store and Google Play. Most recently, I worked full-time as Tech Lead & Developer on a Flutter app with a Supabase backend and a SvelteKit admin interface, powering multilingual content and ML-powered, embedding-based recommendations via vector search.
In 2024 I expanded my skill set by completing a 7-month Data Science & Artificial Intelligence Bootcamp at Le Wagon. This program provided me with hands-on experience in building and deploying data-driven solutions. Key skills: Python, TensorFlow, scikit-learn, LangChain, RAG, Transformers, Docker, Streamlit, Data Analysis & Visualization, Machine Learning & Deep Learning, MLOps & Deployment.
Personal Traits & Neurodiversity: Beyond my professional skills, I am a nerd with a passion for understanding the inner workings of things. My self-taught expertise and natural talent to hyperfocus on various topics, enable me to immerse myself deeply in complex tasks. My neurodiversity empowered me to continuously improve my approaches to work and life, problem-solving abilities, stress-resistance, high frustration tolerance, creativity and relentless drive. I define myself as non-binary.
