CI pipeline with Gitlab for Go project: Build & test Go projects in container. Provide template for other projects.

Ads delivery cross promotion: Performance critical scalable microservices in Go. Using Redis as a cache. Using Nats to receive data from other microservices, Kafka to store all events related to the ads to a data pipeline and gRPC for request-reply to other services. These events are processed from Kafka and then stored on S3 for analytics and data mining. Service is used to select the best potential advertisement campaign for every ad request. Handling tens of thousands of events per seconds. Deployed in Docker container with HELM on a kubernetes cluster running on AWS. Highly tested microservices with code coverage > 90% and code review on everything.

Coordinator: Library written in Go implementing the Bully algorithm to elect leader among instances over Nats.

Transfer: Analysis, development, maintenance, support of Single Page Application (Redux + React, ES6+, JSX, SaSS, Mocha, Chai, Sinon, Localization: EN, FR, NL) and backend (Java 8, Tomcat 8, JAX-RS, Hibernate, JUNIT) connecting to Oracle 11g, MySQL, cache (Redis) and a secure FTP server (proprietary) containing sensitive documents (accounting, payroll, salary, …). In front of load balancing running on RHEL 7. +1000 downloads/day for 3000 customers in Belgium and France.

Portal: Analysis, development, maintenance, support of Single Page Application (vanilla JS, CSS, Sass, HTML, Mobile website, Localization: EN, FR, NL) acting as Single Sign On web app for 20+ web apps with users in 8 different Oracle, Active Directory, MySQL and a FTP server (see: Transfer) in Belgium and in France. Backend written with Java 8, Tomcat 8, JAX-RS, Hibernate, JUNIT. In front of load balancing running on RHEL 7. https://online.groups.be/

2FA: Single Page App (JavaScript (jQuery), CSS, HTML, Mobile) and a backend (Java 8, JAX-RS, Hibernate, Swagger, Apache, RHEL). Implemented 2 factor Authentication to secure user accounts by adding extra security measure to customers with higher access credentials (sensitive data, salary, accounting, …). Users must provide a login/password + 6 digits code (changing every 30 seconds) to connect to Portal (see project Portal above). The code is generated on their smartphones (iOS, Android, Microsoft) by a mobile application.

Translation: Analysis, development, maintenance, support of Single Page Application (Redux + React, ES6+, JSX, SaSS, Mocha, Chai, Sinon, Localization: EN, FR, NL) and backend (Java 8, Tomcat 8, JAX-RS, Hibernate, JUNIT). Internal project meant to be the intersection application between documentation and the internationalization (i18n) of all customer facing application.

CI/CD pipeline: Migration from gitosis to gitolite to GitLab in 2 years time with 100+ repository. Running Gitlab and Gitlab CI inside Docker containers (multi servers). Configuring Jenkins (for Java) and Gitlab CI (for Node.js, JavaScript). Preaching the benefits of writing tests made this possible.

Buildman: Node.js server allowing every team members (technical or not) to build and deploy any applications (web app or java server, version or branch) in one click. This tool also has self­-update and can update other internal tools. The challenge was to configure user access on RedHat Linux with SELinux. Technology Stack: Node.js, Express, git, grunt, terminal.js, SonarQube, RedHat Linux, SSH, BASH.

Analytics: Setup monitoring/alerting ELK. ElasticSearch (search), Logstash (gather logs), Kibana (visualization), Golang (mail client). Gather logs and statistics from web applications and servers + alerting developers (email only) when a customer has an error.

Presentation: Teaching web technologies, agile methodology, unit testing, integration tests and e2e tests to others developers. Presentation to team leaders of git based workflow, merge requests (GitLab), dependency management (Nexus), continuous integration (Jenkins, GitLab CI + Docker), issue tracker (Redmine, GitLab), wiki (MediaWiki, GitLab).

Code quality check: Install and configure SonarQube (running inside Docker containers) for code quality and technical debt tracking.

Writing reports: Conferences, meetings, projects requirements analysis. Example of conference report: https://docs.google.com/document/d/1ahblUs2BaIyEdtQamSX7O9XwRi1GiOZQ4W-G48CooIo/edit?usp=sharing

Research over the MPLS protocol: Multiprotocol Label Switching (MPLS) is a type of data-carrying technique for high-performance telecommunications networks. MPLS is a scalable, protocol-independent transport. In an MPLS network, data packets are assigned labels. Packet-forwarding decisions are made solely on the contents of this label, without the need to examine the packet itself. This allows one to create end-to-end circuits across any type of transport medium, using any protocol. The primary benefit is to eliminate dependence on a particular OSI model data link layer (layer 2) technology,
