2021 ? 2024: application to visualize and manage sensor data


Role: self-employed

Customer: Geodata IT GmbH, Graz, Austria


Tasks:

  • Frontend architect, team facilitator and developer for an application to visualize and manage sensor data, e.g. to alert when the settlement of buildings above a metro construction site exceeds a defined limit value.
  • Successful implementation of an architecture that ensures data consistency and reliability as well as maintainability.
  • Establishing an agile development process.
  • Introduction of regular domain modeling meetings to develop and maintain a common understanding of the domain throughout the team and to use the same terms for the same things (ubiquitous language).
  • Supporting the Product Owner in regular meetings to maintain the sprint board and backlog, to divide up user stories that are too large and to define acceptance criteria.
  • Introduction of ?Geodata University?, a short weekly space where team members can introduce their colleagues technologies, processes or best practices relevant to the code base or development process.
  • Facilitating a culture shift in the dev team from ?we imagine what customers might want in the future? (and by that building generic, complex and expensive solutions) to ?we focus on what the customers actually want now? (keeping the software precise, clean and implementing it around a clean domain model so that it can be expanded in the future in any yet unknown direction at low cost).
  • Streamlining the release process by introducing and implementing feature toggles, raising awareness for breaking changes (API, database), introducing concepts such as blue-green deployment and automatic reloading of the frontend at safe points.
  • Training colleagues in reactive programming, principles of clean architecture, and clean coding.
  • Frontend development: Mainly low level infrastructure code and tools and libraries that are used throughout the system. Visualization in complex diagrams and report generation.


Skills:

DDD, RxJS, Typescript, Angular, eCharts, Ionic/Capacitor, Material Design, JsonRPC, C#/.NET, Neo4J, PostgreSQL, OpenLayers, i18n, Swagger, Azure, Scrum
