This section comes right after the header and usually contains work experience, industries, and skills. That is, everything you haven't or have already written in other sections (see below for the utility of repetition). But there are tricks that help you stand out:
1) Structure the text. Continuous text is more difficult to read, so make it visually readable (at least with indents, short sentences, subheadings, enumeration, etc.).
2) Highlight your strengths. Tip: No clichés like "productive," "communicative," or any other empty words. These words don't mean anything, because that's what everyone lists. The abstract is boring, so talk about yourself through achievements/experiences. For example, "participated in the development of an educational B2C project", "increased web API response rate".
3) Show the direction of development. If you are a PHP developer but want to become a Python specialist, say so. But only if you're actually taking steps in that direction, not just sharing dreams.
4) Add contact information (phone, email, Viber/WhatsApp, Telegram). This will save time: if you fit all the criteria, you will be contacted directly, not through LinkedIn messages.
5) Specify additional information. Social media (Facebook, Instagram), links to your business card site, portfolio, your publications on YouTube say a lot about you, and also prove that you are a real person, not a bot.
