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.

Worked directly with clients as a consultant, assisting in the definition of requirements and helping them to make the best technical decisions.

Experience

Mobee

https://play.google.com/store/apps/details?id=br.com.ecxus.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.

Energy

This is a system that integrates all Ecxus' automation modules available on TCP/IP or RS485 networks to a single point. It defines an event-based protocol to establish communication among them and provides a REST API for interacting and programming each controllable electronic device.

The system was built using microservices architecture, focused on scalability and low latency.

Brascar

A totally scalable and low latency auction system built with microservices, message queues, and push notifications using Amazon EC2, Elastic Load Balancing, Amazon RDS, Amazon S3, and Amazon SQS solutions.
