Projekthistorie
- building and running systematic electronic trading operations in the cloud (AWS-native, built entire solution architecture from scratch, low-latency and event driven)
- strong experience in Domain Driven Design in the financial sector
- strong experience in developing highly scalable cloud solutions and microservice architectures on AWS
- strong experience in developing and deploying production-grade backend services with JavaScript / TypeScript (Node.js, Ts.ED), Java (Spring Boot) and Rust
- architecture includes a highly scalable real-time data streaming pipeline that streams and warehouses financial Big Data from arbitrary providers and normalizes it for real-time consumption in downstream systems (historical data is used for in-depth analysis and data-driven decision making)
- expanding BidFlow Technologies’ trading platform on a continuous basis involves event-driven solution architectures, Big Data management, DevOps, distributed systems, backend/frontend development, data science and more
- played a key role in a newly established IT infrastructure team with significant impact on the design and development of a completely new AWS cloud solution (highly scalable API facade to unify and centralize various business domains)
- experience in Domain Driven Design in the energy sector
- API facade became an important component in E.ON’s larger ecosystem of smart home services that manage solar panels, heat pumps, electric vehicles (EVs), batteries etc. in flex tariffs
- (higher-level goal with flex tariffs: utilize the grid to establish virtual power plants (VPPs))
- strong experience in optimizing solution architectures for maintainability, scalability and cost-effectiveness
- established state-of-the-art identity and access management mechanisms including advanced security concepts as well as identity federation
- delivered quality set the bar to a new level in the whole division
Testimonial
"I worked with Tobias for approximately 14 months on a shared project. His deep AWS expertise and proactive approach across various topics were an incredible asset to our team. He consistently delivered smart, high-quality contributions and demonstrated a strong ability to strike the right balance between pragmatism and sophistication. It was unfortunate to have our project come to an end — anyone would be lucky to have him on their team!"
Dr. Robert Höttger - Tech Lead
- collaborated closely with Computer Science professors and colleagues to run university teaching operations (assignment feedback, exam supervision, exam feedback)
- professors and colleagues alike valued my dedication and noteworthy quality of work
- experience in developing backend services with Java Spring Boot in the context of academic exercises
