• SIGFOX - Software Engineer

  LABEGE 2016 - maintenant Being part of the Integration & Validation team at Sigfox, I'm currently involved in the development of a Python/Django automation platform to run and manage functional tests used to validate the new software versions of the Sigfox's base stations (testing for non-regression and detecting potential problems).
  
  The solution we are currently working on is base on Python/Django.
  
  Technical Environment :
  + Python 3
  + Django 1.9
  + Jenkins : Unit testing, building and deployment to testing/staging server
  + Linux environment (desktop & server)
  + PostgreSQL
  + Jira (& Confluence)
  +BootStrap (& web technologies)
  + Git/BitBucket (& previously SVN)
  + Docker

• Alten Technology France - Consulting Software Engineer at Sigfox

  Boulogne Billancourt 2016 - 2016 Worked at Sigfox (Toulouse, FR) on a Python/Django project :
  Development of an automation platform to run and manage functional testing of Sigfox's base stations.
  
  Technical Environment :
  + Python 3
  + Django 1.8
  + Jenkins : Unit testing, deployment to test/staging server, Selenium tests
  + Linux environment (desktop & server)
  + PostgreSQL
  + Jira
  +BootStrap (& web technologies)

• E-DEAL - Java Software Developer | Internship

  Montrouge 2015 - 2015 E-DEAL R&D Unit :
  My mission was focused on research, test & implementation of different strategies to improve E-DEAL CRM data access performance.
  By the end of my internship, the global performances of the application in our testing environment has been improved by 11%.
  
  Three major milestones composed the project :
  
  ## 1. Define and build a reference environment ##
  
  In order to assess the performance of the system before and after the modification of the Data Access layer, I had to build a reference environment to be able to validate the results :
  - Generation of realistic and valid high-volume dataset (15M+ records).
  - Database optimization and population (PostgreSQL in particular).
  - Creation of advanced JMeter scenarios to accurately simulate user's behavior.
  
  I wrote a "PostgreSQL Performance guide" (in English) applied to the E-DEAL environment in order to explain in detail the optimization steps.
  
  ## 2. Modification of the Data Access layer ##
  
  Those modifications primarily implemented the global use of Prepared Statements in the application :
  
  - Added Statement Caching using specific JDBC's capabilities.
  - Test and integration of the HikariCP connection pool to manage open connections of the application
  - Added JDBC advanced configuration using Java Reflexion API.
  - Added Postgres accent insensitive search ability.
  
  Each modification had to be validated (performance wise) using JMeter load-testing scenarios.
  
  ## 3. Deployment and load-testing in the Cloud ##
  
  I used the Amazon Cloud Computing Services (AWS) to run the JMeter scenarios with thousands of simulated users to assess performance, and to identify potentials bottlenecks as well.
  (Linked diagram shows the Cloud environment I was administrating to run the tests)
  
  Technical environment and technologies :
  + Linux environment (Server)
  + Java / J2E : E-DEAL CRM solution
  + JMeter : Load testing
  + Postgres/Oracle
  + Python & Benerator tool : Dataset creation
  + Git
  + Maven
  + Tomcat
