Oh man, a disorganized Lattes is always a problem, especially for someone doing a master's degree. First, clean everything that's there - remove duplicates, get rid of old publications nobody wants, that random talk from 2015. Then start from scratch: put your education in reverse chronological order (master's first), describe each professional experience well with what you actually did, not just the job title. In the productions section, separate things properly: articles published in journals or even at conferences go in bibliographic production; then comes work presentations, research projects. Each thing in its place. Lattes is kind of annoying to work with, but spend some time understanding how it actually works, because changing things later is more of a hassle.
For what stands out, think about it this way: your master's probably generated articles or advising work? Put that in a place of honor. If you have experience in industry or in the lab, detail the project you worked on, what results came out. Avoid leaving big blank spaces and confusing dates that make it look like you disappeared for a while. A tip that works well is reviewing it every 3 months, because leaving it to update once a year makes the resume look stale.
What's your engineering area, by the way? And do you have a publication or are you in the process? That changes a bit how you're gonna structure the production section, because if you're waiting for an article to come out, you put it in submission anyway.
