After 3 years at HETIC in a more general digital training program, I decided to take the CTO & Tech Lead program. This course provides expertise in infrastructure and methodology to be used in all circumstances. It also provides versatility in terms of the vision to adopt, depending on the project, the team or the company. Teamwork is a very important part of our projects and has enabled me to consolidate my team spirit over these 2 years.I spent time working on several personal projects, exploring both frontend and backend development to learn and experiment. However, my passion lies mainly in the field of DevOps, where automation, testing and deployment have captivated my interest. I had already started experimenting with some fairly simple Debian projects, such as deployment, log management and web server usage, a few months before joining my training program. During the course, I was able to push my skills even further, notably by immersing myself in technologies such as Docker and Kubernetes.I also studied a lot on my own and on learning platforms such as Dyma to push my frontend and backend skills and enable me to go much further in my personal projects and improve myself.
