Designed and built a robust web application for the Colombian Ministry of Defense, Increased accessibility of housing services information for military and police personnel, Implemented comprehensive user tracking with Google Analytics and custom API metrics,Utilized ReactJS, NodeJS, Strapi, and PostgreSQL for development, Designed user-friendly interfaces for both program users and administrators.
We perfectly copy the UI design that clients give us to the browser through a good CSS implementation so that each product looks just as the client wishes, my work with ReactJS and vanilla CSS allows me to be very flexible with all DOM elements when creating an application.
I have created applications with which we can access the device's sensors from the browser, such as the camera or the inclination and direction sensors, to create applications that allow us to give a more immersive experience.
With reusable templates and components, I've more than halved the time to deploy platforms to new clients, even if the design is totally different from one to another.

Print more than 10k Items
This project tackles displaying a massive list (over 10,000 items) with smooth scrolling, filtering, and sorting. It achieves this by only rendering a small chunk (around 60 items) at a time, loading more on demand as the user scrolls, and utilizing a virtual DOM to efficiently manage the data without overwhelming the browser.

Imagine a web platform that fully integrates with your Discord server. Here, you can create and manage events, set up rosters, and even define custom Discord channel templates specifically for these events. Each participant is automatically assigned to their designated channel in discord according with the web setup, streamlining the entire process.

The application simplifies the buying process, offering a user-friendly interface for both administrators and customers.
