I am preparing a project portfolio for a job application in which I describe some of my completed projects in my current role. While the software is still in use today, the projects themselves are completed and I don't work on it anymore. The project description contains of a description of the software itself, technologies used, and some project circumstances that are somewhat relevant to something mentioned in the job description.
I am currently using mixed tenses in my descriptions, but I am unsure whether that's correct. An example:
I developed a X service for enterprise customers with feature A and B. Component C is based on state-of-the-art D and enables feature A. [...] The cross-functional project team consisted of multiple colleagues from the F department and the G Lab.
The development of the service as well as the project team are clearly things of the past, so I use past tense. However, the service still exists, so I am using present tense. However, I imagine this could be a bit strange when reading?
What's the correct use of tenses in this specific situation?
