Zety is a great place to start. It is a paid platform but you can build your resume and preview the result (you'll need to pay to export it). That way I think you'll see how most professional CVs is presented. They also have a nice cover letter builder too.

Hi everyone! I'm Bolbo, a newbie developer and I want to start my own company in the future. I grew up without computer for most of my teenage years and my first exposure to "programming" was visual basics on excel which resulted in PTSD for a 17 years-old me. I loved tinkering with open source projects but ultimately never really learned to program anything since high school (almost 8 years ago) until last month, when I stumbled upon freecodecamp and the grasshopper app . I hope I can learn a lot from this community and become whatever I want to be in the future! So, thank you Sandeep Panda and team for this great platform and thank you Quincy Larson and all contributors to FCC! Cheers, Bolbo
