What I'm looking for

I'm looking to build observable, reliable data platforms that combine ingestion, modeling, analytics, and ML services. I value modular architecture, testability, maintainability, and production systems that are ready to scale.

I'm building Zephyrwerk, a production-grade energy analytics platform on AWS using real German wholesale electricity and weather data. I designed its local-first ingestion, three-layer dbt ELT architecture, XGBoost forecasting services, FastAPI APIs, and Streamlit dashboard.

Previously at Robsen Robotics, I deployed industrial computer vision systems that achieved 90%+ defect detection accuracy and processed high-throughput image streams at 10+ items per second. I also built event-driven ingestion and decision systems integrated with robot arms, PLCs, and cameras.

Across my projects, I focus on modular, testable systems: reliable pipelines, documented data models, containerized services, CI, and infrastructure ready to scale.
