I assisted at digitalsalt as a Senior Full Stack Developer, driving the further development of their tender software. Tenders were filtered by AI, summarized, and checked for digitalsalt's expertise. The software helps find suitable tenders and projects for digitalsalt.

After the acquisition of finetunes, where I previously worked, I joined Sony Music Entertainment and its subsidiary The Orchard as a Data Engineer.

Initially, I was responsible for developing a data pipeline that synchronized and updated operational data between the two companies during the transition phase, ensuring a smooth process for finetunes and Sony customers.

Subsequently, I moved to the Data Engineering team at Sony Music Entertainment. There, I designed and implemented ETL pipelines for streaming data to extract information from S3 storage of various providers (including Spotify, Apple Music), transform it into a uniform data format, and store it in our Snowflake Data Warehouses.

For this, I developed event-driven Python microservices, wrote SQL queries, and used tools like dbt, pandas, and other data processing tools. I also worked on analytics APIs that allowed customers to analyze streaming data and gain insights into regional and demographic performance metrics.

To optimize performance and data quality, I used Datadog, Kibana, GraphQL, ElasticSearch, Snowflake, and Python. Additionally, I supported the development of the analytics frontend with React and TypeScript by implementing the connection to our data backends.

At Hive Digital UG, I was responsible as Lead Developer and Technical Director for several complex projects in the area of blockchain and web platforms. My responsibilities included the conception and development of an NFT marketplace, a blockchain analytics platform, and various creator tools that enabled users to easily enter the blockchain world.

I designed and implemented a scalable backend architecture with data pipelines for blockchain transactions, defined database models, and developed RESTful APIs for processing and providing blockchain-relevant data. Additionally, I administered and monitored a distributed system of blockchain nodes, APIs, and servers to ensure stability, performance, and security.

In addition to technical implementation, I also provided consulting services for startups looking to enter the blockchain space – from selecting suitable technologies to developing initial prototypes.

As a team leader, I coordinated a small, interdisciplinary team of three developers and one designer, was responsible for the technical roadmap, conducted code reviews, and ensured close collaboration between development, design, and product management.
