Technical Lead
2013 - PRESENT
Ecxus High Technology
- Guided a team of developers in rewriting a legacy ERP system developed for Hotels called Automo. We aimed to adapt the solution to modern needs and keep it refactorable. Using Spring MVC, AngularJS, Bootstrap, and WebSockets, the team could deliver a system that fits the needs of a whole set of clients, provide a set of intelligent reports, ensure scalability, and deliver a completely responsive web interface.
- Developed an app called Mobee that offers to the hotel guest the control of the whole automation system of his apartment. In addition, it provides access to many hotel services such as a digital menu, check-out, and satisfaction survey; all directly from the guest's mobile phone.
- Implemented an effective continuous integration process using tools like Git (with GitFlow), NPM, Maven, Nexus, and Jenkins so that the team could minimize the effort to keep software stable and save development time. The team actually reduced the release life cycle by half and could improve substantially their productivity.
- Developed a solution that centralizes the license control of all software provided by the company. The solution provides a REST web service (built on top of Node.js and Express) that integrates all instances of installed systems, receiving license update requests and issuing licenses automatically according to customers' financial situation. This solution has completely automated license management, saving resources and eliminating the likelihood of error or fraud.
- Constructed a system that integrates all automation modules available in a TCP/IP or RS485 network and provides a REST API that exposes the module's commands and state.
- Defined an event-based communication protocol for integration, keeping the system reactive and allowing real-time monitoring.
- Implemented an Artifactory server to be used as a local Maven and NPM repository and also to store snapshot builds delivered by Jenkins on continuous-integration workflows.

Senior Software Engineer
2017 - 2019
Mudano
- Built a resource management tool on top of a type of internal project management software using React, EmotionJS, and GraphQL.
- Constructed a plan drawing tool, one of the key parts of our product, using React and SVG. This tool is fairly interactive and implements a lot of SVG animation.
- Supported the build of an internal react component library to be used on different apps as part of the company's design system.
- Optimized the performance of our main product reducing the app load time to 10% of the original time. The main actions behind it were upgrading to Webpack 4, splitting bundles, using file checksum for cache optimization and preloading resources.

Project History
Mobee
This is an app built with React Native that enables hotel guests to control the whole automation system of their room. It also provides access to many of the hotel services such as a digital menu, check-in, check-out, and a customer survey—all directly from the guest's mobile phone. We defined and implemented an event-based communication protocol to integrate the legacy automation modules to the new control system, keeping it responsive and allowing real-time monitoring.
Automo
Automo is a modular ERP focused on the hotel industry with operational, financial and inventory control, as well as important management reports with the purpose of improving processes and monitoring the business.
The system was built on top of the Java platform and integrates via a REST API several add-ons built on web technologies.
