Freelancer profile translated to English.
Back to original languageAbout Jean-Jacques
Graduated from UTC (Compiègne), I intend to strengthen your application maintenance teams through the use of OOP design patterns and by combining a unit testing framework (JUnit, TestNG) with a Java Virtual Machine memory analysis software (Yourkit Java Profiler).
To define myself in two words:
1) Professionally: square (rigorous and organized, I mean)
2) Humanly: knowing how to smooth things over
I have been an IT engineer for over 25 years and have completed 16 missions of more than 6 months with major clients (TOTAL Energies, Agirc Arrco, AXA Banque, Air Force, Caisse des Dépôts et Consignations, Unedic, Chronopost International, Generali Vie...).
I have been practicing Agile methodology for 10 years via Atlassian JIRA.
I value human relationships so that synergy operates within the team to which I bring my good humor and professional commitment.
I also know how to work in complete autonomy and leverage my analytical skills and my extensive experience with the information systems of major clients.
