Back to original languageAbout Tarek
Software Engineer and Developer with over 12 years of experience: I started in startups, and then evolved in IT consulting firms. I have worked on large-scale projects that I have been able to support from the expression of need to production and in very diverse business domains (VAS, E-commerce, Energy/IOT, Banking and insurance etc.) which allowed me to build a multidisciplinary profile and acquire expertise in building scalable, high-traffic solutions.
My latest experience within ENEDIS's data division allowed me to gain an additional role as a Data Engineer and to have a transverse and pragmatic vision for data-driven projects.
