Back to original languageAbout Alioune
Over my ten years of experience, I have worked in areas with high technical and functional richness. Thus, I have a great capacity and have developed a pronounced analytical mind and an aptitude that have allowed me to solve many complex problems encountered in the telecommunications and healthcare sectors.
My constant exposure to real-time production environments qualifies me as an ideal candidate to maintain and correct source codes deployed in your clients' information systems.
Finally, I am passionate about everything related to backend performance, such as analyzing SQL queries that take too long, searching for bottlenecks in microservices, and optimizing code that consumes too much memory.
