Stacktile helps development teams to understand DevOps tools and techniques easily and put them quickly into practice. Furthermore, their web app allows software companies to provide interactive documentation to their prospective customers to increase conversions.

Making something
out of almost nothing

When I started, they already had a beautiful logo, but only a logo?! I had to define typography and color palette.

What is the developers' color? Black & Green? Ugh! A bold logotype needs a crisp typeface with character and a bunch of fresh colors and patterns with references to their world.

Stacktile: Visual identity background colors

And a special touch to the UI

Much before MacOS Mojave, depending on the user's local time, the background of the application changes color.

Web App UX & UI

I created a questionnaire and applied it to a group of users. Furthermore, I reviewed the Piwik analytics, implemented and analyzed Hotjar data to refine the user stories, user journeys, and wireframing boards.

During the time I worked there, I did countless iterations like this to fine-tune the UX and UI of the application.

Not always what we expect happens

For the launch of the web app, we created two landing pages with different designs to test which of them would convert better. I was positive that the version 2 (screenshot attached) would be the winner, though, numbers showed that version 1 related better with the target audience.

More services, more landing pages

As mentioned before, Stacktile also provides full-stack development services; they also open-sourced the company's website monitoring technology. I designed two landing pages for each of those areas, and A / B tested them using the Convert app.
