PROFILE
Julian Psotta
Contributed to GIScience/openrouteservice by developing scalable multi-profile routing and foundational data export features, focusing on robust backend and CLI tooling. Leveraged Java and Bash to implement a modular CoordinateGenerator with matrix integration, CSV export, and a command-line interface, supporting automation and downstream processing. Enhanced performance measurement through benchmark integration and load testing with Gatling, while strengthening code quality via extensive refactoring, SonarLint-driven cleanup, and improved logging. Improved CI/CD pipelines and Docker-based workflows to accelerate releases and ensure reliability. Addressed critical bugs in matrix output and request handling, and expanded test coverage using Mockito and JUnit for maintainable, high-quality code.

Feb 1, 2025February 2025 highlights for GIScience/openrouteservice: Delivered foundational CoordinateGenerator with applyMatrix integration and basic matrix handling; implemented tests and mocks for robust TDD coverage. Strengthened testing infrastructure with Mockito-based responses, global mocks, and a generic CoordinateGenerator path to improve test reliability. Fixed critical matrix output issues and API usage: corrected matrixResults, updated output columns to lon/lat, and resolved the deprecated execute call. Added downstream-ready CSV export via writeToCSV and introduced a CoordinateGenerator CLI to support automation. Also initiated internal refactors to improve maintainability and performance, including restructuring functions and detaching response processing. These changes collectively reduce downstream integration risk, improve data quality, and accelerate routing workflows.
