Getting Results
Below is a selection of my professional achievements that I am proud of. They provide a glimpse into the results I can get.
GraphQL Platform Leadership at New Work SE
Having played an instrumental role in the platform's development, I was entrusted with the accountability for the GraphQL platform of New Work SE, and:
- Improved ownership, clarity of vision, and execution by developing the product vision for the GraphQL platform and implementing an agile development process with our team that used data-based and organizational feedback
- Ensured fitness for purpose and continued organizational adoption by prioritizing work and managing stakeholders for the critical platform—New Work's standard for backend/frontend communication, serving such high-traffic products as XING, and integrated by 52 engineering teams
- Guided the organization in successful integration with the GraphQL platform in other projects and consulted on software architecture in the early phase of a key project
- Helped our team to level up by sharing knowledge through mentoring, documentation, and onboarding of new colleagues

Open Source GraphQL Algorithm Innovation
I invented, prooved its correctness, and published a vastly more performant algorithm for GraphQL field selection merging that has since been implemented in multiple open-source GraphQL servers. I published it in September 2019 and opened a PR for Sangria GraphQL to add it as an experimental query validation. Shortly after GraphQL Weekly and Meta For Developers featured the algorithm and by the end of 2021, it was implemented in GraphQL Java and became the default algorithm in Sangria.
GraphQL Platform Development at New Work SE
I played an instrumental role in the development of New Work SE’s GraphQL platform:
- Enabled self-service API integration by co-designing and implementing a GraphQL schema-based DSL
- Enabled new usage patterns by inventing a highly efficient GraphQL query validation algorithm
- Facilitated the internal rollout of the platform to 52 teams by training developers, guiding and collaborating on the integration with the platform

I contributed instrumentally to the development of DIGITEC's money market and FX pricing tool:
- Developed and maintained the core component of the system architecture: a publish-subscribe, actor-based messaging infrastructure
- Introduced a successful data migration approach from the legacy system
- Significantly enhanced the system performance after careful analysis
