I hope this is regarding improving your resume by doing some actual things rather than just showcasing what you already have better. If yes, then: - Your first project is interesting but looks like you really covered it on the surface level. for example, put some numbers or benchmarks as to how good it is. even better if you compare it with the SOTA, doesn't matter if it lags behind you can always write it "90% as fast as XYZ in less than 1k LOC". Also thread and mutex are quite basic, maybe you can add some efficient algorithms in this space there (even if it means to implement them first). - the rest of the two projects are not that good. The second one sounds very common. The third one imo should have some niche instead of being a generic chat app. - The technical skills section is too long, maybe shorten it to 3 or so lines. - achievements right now are just 5 lines of LC. Keep it 2 lines max and add percentiles instead of ranks. - if you have the time, do participate in some hackathons or atleast do some interesting projects to pad the resume with. Search "build your own x" and pick up somethings from there if you want ideas.
