What I'm looking for

I’m looking to grow my analytical impact by supporting data-driven decision-making. I want to extract, validate, and analyze real-world data with SQL and Python, and communicate insights clearly through dashboards and visualization—while building reliable data pipelines.

I’m a Data Analyst with a software engineering background, focused on turning real system data into reliable insights. I enjoy understanding how data is produced and consumed end-to-end, then extracting, validating, and analyzing it with practical SQL and Python workflows.

In my recent role at Automotive Synergies GmbH & Co. KG, I developed 6+ mobile applications and owned end-to-end data collection, validation, and consumption across industrial, automotive, and IoT systems. By integrating backend services to collect, persist, and retrieve application and device data, I improved data availability and consistency by ~25% across connected platforms, and I implemented Bluetooth Low Energy (BLE) streaming for continuous, real-time device data collection.

I also bring strong data integrity habits: I reviewed application logs and backend responses daily to monitor data integrity, identify anomalies, and analyze application behavior. I collaborated closely with hardware, QA, and Scrum teams to support data validation and iterative improvement of data-driven features.

Earlier, at RMSTegos GmbH, I coordinated 10+ team members and standardized workflows to improve customer-facing KPIs by 15%, while designing quality and cleanliness control processes that exceeded benchmarks by 20% and contributed to a 10% increase in revenue. Before that, I worked as a SQL Database Developer where I optimized SQL queries and implemented indexing strategies, reducing query execution time by up to 50%, and I designed relational database schemas to support scalable, high-integrity querying.
