M.Sc. Data Science — ML & Data Engineering

Building practical ML systems, from deep learning to real-time data pipelines.

About

Who I Am

M.Sc. Data Science student based in Berlin, transitioning from 3+ years as a production software engineer into applied machine learning. Focused on deep learning, classical ML, and building reliable data pipelines — bringing engineering discipline from a live insurance platform into data-driven and ML-focused work across the European market.

DR Detection with Deep Learning

5-class diabetic retinopathy severity grading from retinal images.

Problem
Manual DR grading is slow and subjective, risking missed early-stage diagnoses.
Approach
Trained and compared a custom CNN, ResNet50, and MobileNetV2 (transfer learning) on the APTOS 2019 dataset, deployed as an ensemble.
Result
Shipped as an interactive Gradio demo on Hugging Face Spaces.

Live Grocery Price Tracker (System Design)

Real-time price comparison architecture across six retailers, delivered via Scrum.

Problem
Consumers can't easily compare grocery prices across retailers in real time.
Approach
Designed a scraping/streaming pipeline (Selenium, Kafka, Spark) with a PostgreSQL backend and FastAPI/React frontend — led as Scrum Master over a 5-person team across sprints.
Result
Delivered full system design, sprint backlog, and architecture as the graded deliverable.

55-Country Population Trends Dashboard

Analytics on 65 years of population data across 55 countries.

Problem
Which countries are aging or growing fastest, and what's driving the divergence.
Approach
Analyzed 1960–2024 population data with Python/pandas and built an interactive HTML dashboard.
Result
Presented via PowerPoint deck and live dashboard walkthrough in a 1:1 professor review.
