Data Engineer at Idealo who improved data quality and migrated analytics workloads from Presto to Trino.

Germany

Message

At Idealo, I designed and maintained Scala/Spark and Airflow pipelines for analytics teams. I also corrected historical transformation errors and tuned processing to improve schema integrity and pipeline efficiency.

I integrated Monte Carlo to help teams set up data observability monitors and quality checks. I contributed to an AWS Glue, MWAA, and Terraform infrastructure MVP for post-ingestion processing, and worked with the Security Champions group to reduce data platform vulnerabilities by 30–40%.

At BlackRock, I owned delivery of a Python and AWS Glue ETL pipeline for a custodian, automating ingestion and transformation with unit testing. I also expanded a Java Spring backend for the Proposal Generation application and resolved operational bugs in Ruby on Rails.

Earlier, at Airspace Systems, I expedited backend features and connected services with hardware, machine learning, and an Android application. At HummingBird Web Solutions, I contributed to enterprise application development and delivered custom features for the Avactis shopping cart platform.
