Working for 8 years as a Software Engineer on Web Applications using mostly Java and Javascript, I can discuss architecture design and customer's needs, maintain functional and technical specifications and documentation, develop a Web Application from scratch, setup some CI/CD practice, and fix production bugs.
I took part in teams of many sizes, from 5 members to 40, local and remote.
If the project is small, I can work alone as I am currently maintaining some personal projects.
