Experience
LinkySupervision Project
LinkySupervision is a key part of the smart electricity metering system in France, meant to guarantee the good health of the 35 million meters deployed in the national territory.
Our priority was to design a solution capable of collecting and analyzing a huge amount of data, approximately seven million messages per day, to contextualize them, detect defects, and correct them automatically. We designed a solution using distributed technologies, SOA principles, and a decision engine based on JBoss BRMS (Drools).
I began as a Java developer and soon joined the expertise team in charge of developing the proof of concept (POC). I organized regular presentations on our POC progression and technical decisions to the rest of the developers. When the POC was validated by the sponsors, I was charged with creating and leading an expert team of five talented developers to design and implement the core modules for LinkySupervision.
