The present disclosure relates to enabling clients to identify qualified developers for software development projects. An example method of operating a developer exchange server includes updating stored progress of developers for mission-related activities, wherein the mission-related activities correspond to features of a software platform, and determining, based on the stored progress of each of the developers, a confidence score for each of the developers for each of the features. The method includes receiving a search request that indicates a subset of the features and corresponding confidence thresholds for each of the subset of features, and in response, determining a ranked listing of qualified developers based on the subset of the features, the corresponding confidence thresholds, and the respective confidence score of each of the developers for each of the subset of features. The method further includes providing the ranked listing of qualified developers in response to the search request.
