Featured Projects

Mercedes-Benz — Test Session Data Collection & Ticket Generation Tech: Python 3.12, wxPython, Playwright, OpenCV, PyTurboJPEG, edge-tts, Google Gemini API, pandas, matplotlib, pytest Time: Q4 2025 – Q1 2026 Production desktop tool for vehicle test engineers. When a test driver presses a marker during a session, the tool simultaneously captures video clips, downloads diagnostic reports, cuts logger traces, fetches vehicle state history, and generates AI-powered defect descriptions — all in parallel, aggregated into a ready-to-file ticket. Built on a producer-consumer pipeline: marker events broadcast to bounded queues consumed by independent feature workers with timeout handling, circuit breakers, and automatic thread restart with exponential backoff. Scale: 92,000+ lines · 261 source files · 1,000+ tests · 52+ architecture docs Impact: Reduces per-incident data collection from 30+ min across 5+ systems to under 10 min Internal tool — source not publicly available
SemesterModuleMatching — 3-Layer PyPI Package Suite WebUntis Public API Client, HSRT Timetable Wrapper & Elective Schedule Optimizer CLI Tech: Python 3.10+, requests, icalendar, WebUntis REST API, GitHub Actions, PyPI Trusted Publishers Time: Q1 2026 · Apache-2.0 License Three packages forming a layered dependency chain for querying public university timetable data and optimizing elective course selections. The first two are published on PyPI; the CLI tool installs directly from GitHub: Layer 1 — webuntis-public: Generic Python client for the WebUntis public REST API. No auth required. Supports class listing, timetable fetching with rate limiting and frozen dataclass models. Layer 2 — hsrt-timetable: Convenience wrapper pre-configured for Hochschule Reutlingen with known program codes, semester-to-group mapping, and academic calendar utilities. Layer 3 — wahlfach-matching: CLI that aggregates subjects across class groups, scores electives against schedule conflicts and user preferences, and exports ranked results as ICS calendar files. Each package has its own repo, CI/CD pipeline (GitHub Actions + PyPI Trusted Publishers), and test suite.
ALEE — Educational Question Generation System Research implementation using one-shot multi-layered small LMs, refined through aggregated data-backed expert suggestions and DSPy Chain-of-Thought. Leibniz-Institut & University of Tubingen.
