It exposes public routes for authentication and user creation, plus JWT-protected routes to list, read, update and delete users. Built with ASP.NET, C# and MongoDB.

A film catalogue project built around The Movie Database. The source repository is no longer available, so the details recorded here are limited to the stack: React, Firebase, Tailwind CSS and Lucide icons.

A viewer for GitHub profiles that presents user information through charts and statistics instead of raw lists. It shows profile data and repositories in a readable layout and updates without a full page refresh. Built with React, TypeScript and Styled Components.

A TypeScript REST API built with Node, Express and MongoDB, kept as a starting template so later projects can skip the repetitive setup. It already ships with sign-in and sign-out backed by JWT and with routes to create and read users.

The second version of Geisiel Melo's personal portfolio, rebuilt on Vite for better performance and extended with an archive page and direct contact. Its README lists React, Node, Tailwind, Framer Motion and the GitHub API as the stack.

A study project that builds an advanced data table with the React Table library across five progressive stages, ending with page-by-page navigation through Prev and Next buttons. Built with React, CSS and React Table.

A weather application built as a personal project. The source repository is no longer available, so the details recorded here are limited to the stack: React, Node and Styled Components.

A four-step form covering contact, company, project and completion. Data is submitted one step at a time so each screen stays short, and a simple check stops the user moving on with empty fields. Built with React, Node and Styled Components, following a layout designed in Figma.

The first version of Geisiel Melo's personal portfolio, a site built to present his projects and make it easier to get in touch. Its README credits Brittany Chiang's design as the inspiration. Built with React, Node and Styled Components, and one of his first React projects.

A newsletter sign-up built on top of the Mailchimp API. The form collects a first name, last name and email address, registers the contact in Mailchimp, and returns dedicated success and error pages. Built with HTML, CSS, JavaScript, Express and Bootstrap.

A calculator that started as a course exercise with basic arithmetic and grew into a scientific one. It handles trigonometric and logarithmic functions, exponentiation, square roots and parentheses for complex expressions, and keeps a history log of previous calculations. Built with HTML, CSS and JavaScript.

A browser version of the Simon memory game. Every round adds another element to the sequence the player has to repeat, and a single mistake ends the run. It has start and reset controls, score and max score tracking, and a responsive layout. Built with HTML, CSS and JavaScript.

A virtual drum kit with seven pieces: bass drum, snare, hi-hat, tom, cymbal, floor tom and cowbell. Each pad responds to both keyboard and mouse input, and the layout stays usable on desktop and mobile. Built with HTML, CSS and vanilla JavaScript.

A desktop application for schedule management, described in its README as Geisiel Melo's first functional Python application. It collects client information and stores it in a local SQLite database for later reference, with an interface laid out in Qt Designer. Built with Python and PySide6.
