Some really impressive stuff in there! I really appreciate your explanations for each project and also that you’ve explained your roles for each & how your role fitted into the team – too often in my old art team we would look through portfolios and it wasn’t clear what part of a team project the designer had contributed themselves.
One thing I’d possibly consider looking at is the typography, if you look at a section like this:
I think you could have a bit more hierarchy and contrast there. Sure the title is the biggest, but all the font weights, letter-spacing, character widths etc. are relatively similar and the date / category isn’t too far off the project teaser description in terms of its hierarchy.
So perhaps you could look at a bolder sans-serif to contrast with your use of Lora & make the dates / category smaller or less prominent?
PT Sans is a great font and fits the technical style of your work well, but you could also try a few other sans-serifs that might feel a little less cold / corporate and inject a bit of personality, too. A different sans-serif could also help with the contrast as you could experiment with ones that for example had slightly wider character widths or were more geometric etc. to contrast more with the character shapes of Lora.
I’ve also noticed your using both Roboto and PT Sans - but I’d stick with just one throughout as there isn’t enough contrast between the two to warrant using both imo.
One final thing is that you could possibly look at different color palettes to show each project against instead of the homepage colours - might give a nice contrast to the sites themselves and allow you to use brighter / bolder colours should you want to. I think you could still represent the technical nature of your work well but perhaps feel a little less cold in the process. If you wanted you could look at a platform like Adobe Color and see if you liked any of their color palettes.
Hope some of that’s useful!
