When you land on en.andros.dev, you see a clean portfolio site for a developer named Andros Fenollosa. The page describes a full-stack engineer with experience at big companies, a passion for functional programming, and a history of writing books and courses. All of that is plausible, but the site itself offers very little outside verification.
There's no web archive history, no social media links on the page, and the WHOIS ownership data is unreadable due to a lookup failure. So while the site is technically well put together — fast loading, properly encrypted, and free of malware — you're essentially taking the person's word for who they are. For a portfolio or blog, that's not unusual, but it does mean 'is en.andros.dev fake' isn't a question the data fully answers.
If you're considering hiring this person or buying one of their courses, the safest step is to cross-reference the name and claims on professional networks like LinkedIn or GitHub. A legitimate developer with the experience described should have a larger digital footprint elsewhere. The site itself isn't a scam, but it's also not a complete picture on its own.
