Trekhleb.dev is the personal portfolio and blog of Oleksii Trekhleb, a senior software engineer at Uber and creator of one of the most-starred repositories on GitHub. If you're wondering whether this site is legit, the evidence is clear: it's a genuine personal project, not a scam.
Unlike many portfolio sites that hide the owner's identity, this one puts a real name, photo, and links to LinkedIn, GitHub, and other profiles right on the homepage. The domain has been online since 2021 with a clean record on all safety checks. And the owner's open-source work is widely recognized — his JavaScript algorithms repo has nearly 200,000 GitHub stars and is referenced in academic papers.
For a personal blog or portfolio, there are no red flags here. The site doesn't ask for money, logins, or personal data. The lack of a privacy policy or contact form is normal for this kind of site. If you're considering using any of his open-source projects or reading his articles, trekhleb.dev is a safe place to visit.
