Experience

UpTimeLine

https://uptimeline.com/
UpTimeLine is a website uptime monitor that checks to the minute whenever a website is online and notifies the user if it's not. The stack includes MongoDB, Serverless, AWS Lambda, Node.js, Next.js, GitLab CI/CD, and Jest.

Initially, I developed this project so I didn't need to purchase similar paid services. I later polished and published it so anyone can use it for free. It's currently monitoring about 200 websites, most of which aren't mine.

Usophy Web App

I created a React web app for browsing Usophy's library, allowing for authentication, payment, subscription, and subsequent reading of the library's books. It also allows taking notes and highlighting.

The app is responsive, works well on mobile phones and tablets, and functions as a desktop app. It is also well indexed in Google, including the dynamically generated pages for each book.

GiteInNatura

https://www.giteinnatura.it/
GiteInNatura is a WordPress blog with a custom theme that I developed. The blog is about the best hikes in Piedmont, the Italian region I live in, and the articles are written by a friend and me. I developed it during the COVID-19 lockdown as a way to improve my SEO skills.

From an SEO point of view, the website is doing exceptionally well: At the time of writing, the website has less than 20 articles, but half of them were in the first position on a search query on Google while receiving several hundreds of clicks every day—even competing against much larger websites like Wikiloc and Gulliver.
