Urban Dog

A simple HTML and CSS project for a dog training company.

I built this project for a client who would internally provide back-end integration. The design complexity is basically regarding little transitions and full mobile compatibility.

.Txt Studio

A PHP project for a linguistic agency.

This was an ongoing project when I started working on it. The client was unsatisfied with the code quality and the results on multiple platforms. I refactored most of the HTML and CSS, ensuring the web app worked on mobile, tablet, and desktop of Windows and Mac. I guaranteed iPhone and iPad compatibility on Mozilla, Safari, Chrome, Microsoft Edge, Internet Explorer, and Opera browsers. For Android devices, compatibility was ensured in all formerly mentioned browsers except Safari.


An HTML and CSS project for a digital security company.

The challenge was to create a particular design entirely customized for the client, designing the front-end code. The client would provide back-end integration afterward.

Glass On Time

An HTML and CSS skeleton code for a glass product/service marketplace.

I coded pages related to payments, processing details, and admin and user results, shown in bold at the link mentioned above.

The biggest challenge on this project was turning the app responsive to smartphones and desktops.

THA for Hiring Process

Angular project for the company's hiring process. I passed. This was my first and so far only Angular framework project. The company was hired to create new versions of its multiple education-related applications. The project simulates a dashboard for selecting and viewing details of courses.

RoR Course — Blog Application

A simple blog application developed during a Ruby on Rails course. The design is entirely mine, as well as the choice of using Rails 7 with Tailwind CSS.

For comparison purposes, you may see the original design (https://alpha-blog-6.herokuapp.com/) and compare it to mine (https://rickcardoso-alpha-blog.herokuapp.com/).
