A fact-checking platform that allows associates to review claims from public personalities and evaluate whether they are truthful or not. Personalities can then be ranked based on their honesty scores. It was built in Next.js and NestJS, using MongoDB.

A geographic information system for CPOS to oversee the government's construction work done by private companies. For this project, I led a team of five engineers to build a system focusing on code maintainability and helping users with their daily tasks. Surveyors can input what they see at the construction sites on an Android app, which syncs with the database to feed the system. The government can easily supervise the construction progress and match it with the consumed resources to avoid embezzlement.

Smart storage is placed on buildings and controlled through a mobile app. Users can subscribe to different plans to store their things and request them back when needed. It was built on React Native, Laravel, and MySQL. As a tech lead, I worked in both the mobile app helping to implement components for the UI and the back end using Laravel to secure endpoints and data access and integrating with Stripe to create subscriptions.

A check-in app built in Laravel and Vue.js. It allows owners to register their multiple locations or restaurants, receiving a unique URL, phone number, and QR code for each one. Their customers can use that information to check in at that location, get discounts, see the menu, or be redirected to another page. Owners can see reports with the average check-ins and the peaks and see all data entered by customers on the check-in page, such as name, e-mail, or phone number. I was the tech lead for this project, working with two other engineers to build the system. My roles involved handling the customer's requirements, breaking them down into small tasks for the team, and helping to develop both the front-end components and the back-end endpoints, jobs, and the Twilio integration for SMS check-in.

It is a small service to edit short videos, usually of people presenting themselves or their business, adding a logo, applying fade-in and fade-out effects, playing music, and automatically adding subtitles. This was hosted as a separate microservice to be used by a customer as an extra feature to their software. Everything was done using FFmpeg and Node.js.
