Freelancer profile translated to English.
Back to original languageAbout Jonathan
With over 6 years of technical experience, I am an organized and competent professional, aspiring to put my expertise to work on projects as a Freelancer. My ability to quickly integrate into new professional environments is supported by a strong team spirit and remarkable listening skills. My skills are deployed in four key areas: understanding and analyzing team needs, modeling as well as creating and updating data via tools such as SQL Server, PostgreSQL and MySQL. I also master data cleaning and management, with the possibility of automation using SQL, RStudio, Python and Dataiku. In addition, I am qualified in creating strategic reports for activity management, using platforms such as Tableau Software, TIBCO SPOTFIRE, as well as JavaScript, HTML and CSS languages. Finally, my expertise in Python development allows me to design effective classes and methods and perform rigorous unit tests.
