Denz, a Filipino Open Source Developer, and How His App Became an Instant Viral Hit

A new interactive web app has been making rounds on social media and has caught the attention of travel enthusiasts and adventurers alike. My Philippines Travel Level has become a sensation among Filipinos, particularly those who love to travel and explore the beauty of their own country.

The app lets users shade the provinces they have visited on an interactive map of the Philippines and provides a "Travel Level" score based on how many provinces they have been to. Users can share their scores on social media, allowing friends and followers to see the places they've been to and inspire others to explore more of the Philippines. Since its launch on April 13, the app has gained immense popularity on social media, with Filipinos across the country sharing their maps and competing with friends to see who has visited more provinces.

How the My Philippines Travel Level Works

'My Philippines Travel Level' users assign travel levels to specific provinces by clicking on them

Using the My Philippines Travel Level Map is incredibly easy. Simply visit the website, click on a province, and choose the travel level that best describes your connection with that area. The travel levels are as follows:

  • Lived there (5) – you spent a significant portion of your life in that area.
  • Stayed there (4) – you slept at least a night in that area.
  • Visited there (3) – you spent some hours exploring the area.
  • Alighted there (2) – you just dropped off for a short stopover, layover, or transfer.
  • Passed there (1) – you passed by that area but did not set foot.
  • Never been there (0) – you need to travel there soon.

Once you've finished selecting your travel levels, your travel level will be displayed in the upper right corner of the page. You can also save a copy of your map, which you can share on social media or keep for yourself.

How the My Philippines Travel Level was Created

My Philippines Travel Level web app was created by Denz del Villar, a Filipino software engineer based in Singapore. Denz got inspired by JapanEx, a similar program made for Japan, during his two-year stay in Japan. His desire to have an interactive travel map for the Philippines led him to start working on the project during a layover at the airport in Singapore, despite having no prior knowledge of web development. With the help of ChatGPT, Denz was able to create a graphics-intensive web app in just a few days using React.js.

While ChatGPT provided initial templates and guidance to get started, Denz had to customize and refine the codes to ensure the app worked seamlessly. My Philippines Travel Level Map was shared on Instagram Stories on April 12th and quickly gained popularity among Denz's friends who tested and shared it with others. It was also posted on the r/Philippines subreddit, where it received positive feedback from fellow Redditors.

The Success of My Philippines Travel Level App

My Philippines Travel Level app became an instant hit, gaining a massive following on social media in just a few days. Its success can be attributed to the support of notable personalities like Macoy Dubs, a Filipino content creator with over 1 million Facebook followers, and former Vice President Leni Robredo, who shared her personalized map. Brands also created their own versions of the map, using it for serious and humorous purposes.

The app's success shows how helpful open-source software can be. Denz shared the app's source code with everyone, allowing people to collaborate and create new ideas. This gave more people the chance to use technology. The many different versions of the app prove that open-source software can help people and communities create great things. My Philippines Travel Level app is a perfect example of how open-source software can create positive change in the world.
