• Software Engineer

  • Mar 2016 - Mar 2019

  My main roles were security and authentication specialist, full-stack developer and desktop developer. I was also responsible for implementing the DevOps of the projects.• I created a Java application to work with SmartCards. I implemented a licensing mechanism and a REST API to communicate with a browser. I also developed an AngularJS-like library to interact with the API. The installers for Windows, Linux and MacOS were automatically created with GitLab CI.• I developed a Java micro-service backend for an Android application. It consumes HL7 messages of the prescription of drugs sent by the hospital services. I used RabbitMQ for messages reliability and MySQL for storage. Security was a key requirement.• I implemented a reverse proxy and redesigned the user interface of an existing Groovy on Grails authentication platform.• I implemented filters for ElasticSearch/LogStash to parse logs of multiple systems, written in Ruby.• I developed an OpenID Connect authentication and authorisation plugin for Kibana. I also implemented a plugin for Kibana to manage the configuration of a system that automatically deploys remote services. This work required knowledge of Node.js, AngujarJS, Webpack and Babel.• I implemented several authentication mechanisms (SmartCards, Yubikeys, U2F, NFC and more) for Keycloak. I also developed an API for authentication with an Android application.• I also gave internal lectures, monitored trainees and wrote technical documents about the work. Show less
