Samuel Demir

Senior Data Engineer/Architect

AEW Energie AG

2026 - Present

As a Senior Data Engineer/Architect, I design and develop scalable data platforms and cloud solutions using Apache Spark/PySpark, Databricks, Python, SQL, Docker, and Terraform. I combine cloud engineering, data engineering, data architecture, data analytics, and visualization engineering to deliver complete end-to-end data products. My expertise covers data extraction and integration, Change Data Capture (CDC), Oracle-based data pipelines, batch and streaming processing, data modeling, cloud networking, security and RBAC, infrastructure as code, and modern lakehouse architectures. From extracting data from source systems and building robust, scalable data pipelines to modeling, analyzing, and visualizing data with Power BI and DAX, I cover the entire data journey and build production-ready data products from source to final dashboard.

Master Degree Student

J.M. Voith AG

2019 - 2020

At J.M. Voith AG, I completed my Master’s thesis on anomaly detection in transient operating conditions of hydropower plants, focusing on complex operating sequences such as start-up, shutdown, and water-level changes. I developed data-driven approaches for detecting abnormal system behavior using Python, Pandas, Polars, and Scikit-learn, including data preprocessing, feature engineering, exploratory data analysis, and machine learning-based anomaly detection. This work combined data science, time-series analysis, and domain-specific engineering knowledge to identify deviations and anomalies in real-world industrial sensor data.

Magento2 Web Developer

Zenubia Schmuck AG

2017 - 2018

As a Frontend Developer at Zenubia Schmuck AG, I was responsible for the development and technical operation of the company’s e-commerce platform based on Magento 2. I built and maintained the underlying LAMP infrastructure (Linux, Apache, MySQL, PHP), coordinated product data flows from suppliers into the online shop, and developed standardized import processes for product information. I also contributed to frontend development, data quality management, and the integration of supplier data, ensuring reliable and up-to-date product information throughout the platform.

Formula Student - Battery Container Engineer

DHBW Engineering e.V.

2016 - 2017

As a Battery Container Engineer for the Formula Student team at DHBW Stuttgart, I designed and developed the vehicle’s battery container using CATIA. I conducted composite material testing with carbon fibre, glass fibre, and Kevlar, including shear and bending tests, to evaluate and optimize the structural performance of the container. Through iterative design and material optimization, I reduced the container’s weight by 3 kg compared with the previous year’s design while maintaining the required structural performance. The team achieved 1st place in the Acceleration discipline at Formula Student Germany in Hockenheim and finished 3rd overall.
