Computer vision / machine learning projects
  • Miele (10 months): Developing object recognition models in a smart home research project. Data collection and annotation, synthetic data generation, model training. Pytorch, MLOps
  • Siemens mobility (1 year): Developing MLOps infrastructure for computer vision research. Heavily software-engineering role. experiment tracking, containerization, CI configuration, visualization
  • open-read (6 months): Building an-device text recognition library for android phones. Converting large models to mobile-friendly models, library architecture and implementation. tensorflow, tensorflow-lite, Kotlin, Android, training small and efficient models
  • medimusic (1 year): Large-scale extraction of musical features from audio data (millions of tracks). Implementing feature extractors and setting up cloud infrastructure and pipelines for processing and storage. tensorflow, pytorch, AWS


Data science / forecasting projects

  • foodtracks (10 months): Startup that offers data science services for bakeries. Mix of data science tasks (demand prediction / time-series forecasting) and software engineering tasks (setting up reliable processes for getting customer data into our system). pandas, scikit-learn, CI/CD setup
  • Wayfair (6 months): Large online retailer for furniture. Demand prediction / time series forecasting within the logistics domain pandas, scikit-learn, Google Cloud Platform, BigQuery


Frontend projects

  • Trans Europe Planner (10 months, ongoing): My own project, initial funding through prototypefund. A more explorative way of travel planning. 


Teaching

  • HTW University of Applied Sciences Berlin (3x9 weeks): Teams of 3-5 students worked 9 weeks on data science projects and met with me weekly to discuss progress and next steps. Course design, running and grading all done by me.

PROFILE
Freelance machine learning engineer / software engineer with 11 years of experience, 7 years as a freelancer. Wide skill set covering data / backend / frontend technologies. Strong interest in product and UX.
Previous machine learning projects mostly in computer vision and forecasting. Other data experience with geodata, sensor data, audio data. Strong SQL / database background. Working with the usual pythonbased data stack: tensorflow, pytorch, pandas, scikit-learn, etc. Automated testing, setting up CI/CD, code reviews. Comfortable in AWS and GCP, some experience in azure. Love building data visualisations and frontends, very comfortable in HTML/JS/CSS. Good writer. Happy to mentor
