Back to original languageAbout David
Passionate about technical challenges in Web and Big Data development, and a perfectionist at heart, my passion is to provide simple and clear solutions to complex issues while facilitating long-term maintenance and deployment.
During my previous assignments, I was able to adapt very quickly to meet client needs, show initiative, and critical thinking.
Indeed, in addition to the expected needs, I was able to:
- develop the architecture of several projects
- train interns and junior developers
- optimize the recruitment system with a technical test
- improve the performance of various applications
I am ready for your mission!
