A mobile app for Vaughan Radio (a very popular radio station in Spain for learning English) to offer all their programs as podcasts, adding gamification, connection with social networks, surveys, etc. I focused on implementing the API made in Node.js and assisted with building the app component, using Ionic and Angular.

Once many listeners of Vaughan radio station started using the application, they received very positive feedback because users could participate in the programs with real-time challenges and listen to all programs in the podcast format. As of March 2020, the app had 100,000+ downloads and a 4.5-star rating on Google Play.

A mobile app that allows different management levels at a global bank company to monitor the status of all negotiations and contracts under their supervision. The solution implements different roles at the local, regional, country, and global levels. With this app, they could see all negotiations, amounts of money involved, contract status, documents, and more, including those negotiated by anyone under their supervision.

I led the design and developed the back-end server (REST/API) and the integration with client systems for extracting the information needed. The back end was implemented with microservices, using Node.js, Moleculer, and MongoDB.

The app saved a significant amount of time for managers who previously relied on large and difficult to understand Excel files for the same information.

A website allowing managers of an international sports company (located in different countries) to aggregate the marketing dashboards that they manage so that employees across the company can use, monitor changes, and comment on them.

I designed the architecture and implemented the back end, using a REST API. I also collaborated in the implementation of the front end. The back end was implemented in Node.js and MongoDB, the front end was developed in Angular, and the project was deployed with Jenkins in Kubernetes.

The website enabled all employees to easily access and collaborate in all marketing dashboards in one site, which significantly increased their use and saved time for everyone.

A website for clients who want to find and communicate effectively with potential clients through Twitter. The platform offered users the ability to automate continuous, strong growth in their business or professional Twitter accounts by analyzing and searching for people who would potentially be interested in them (by location, common interests, and more).

I conceived the idea and led its development from the MVP through to a commercial project. I designed and implemented all components—front end, back end, API, database, and more—and even the marketing strategy. The front end and back end were implemented in PHP and the database was in MySQL.

More than 10,000 clients used the platform during the six years it was live. The project was closed in 2019 because of the changes in the Twitter API restrictions.
