– Worked on web customization of the embedded software managing RF equipments. Added specific views/pages for configuring parts of the equipment. (JavaScript, HTML, CSS, C language, Git, quilt) – Worked on RF planification tool, in 3D. It detects line of sight from the floor to the antennas, located at the top of buildings. A map of coverage is done thanks to height data. (prototype) (Google Earth Web API, GWT, Java, JSON, Eclipse, git) – Integrating an Open-Source NMS to the BluWan's Network Elements, using SNMP. (Zabbix, Cassandra, AngularJS, Java, OSGi, HTML CSS, JavaScript, Bootstrap, Ant, Ivy, PostgreSQL, MongoDB, OpenStreetMap Server, Leaflet JS) – I'm in charge in development of the Bluwan FusionNMS, a management system for the network equipment that BluWan produces. Researches had been done to find the right open source tools. After producing a prototype, with SNMP agent simulator, the solution has been adopted and development is going well, with test in charge. Lately, Cassandra has been adopted in order to have a better scalability and performant solution for storing the performance data.
