À propos de Alban
As a senior software engineer, I can strengthen your workforce or bring extra (soft or hard) skills your team may need.
I have been working as a software engineer for 15 years, including two French unicorns.
Over those experiences, I developed my ability to dive into large existing code bases, to design local evolutions or improvements as well as new services integrated into a distributed system. I have a strong focus on the purpose a change serves and I value simplicity.
I am also fond of observability, especially for automating reliability and user satisfaction measurements.
Hiring tech profiles is also a topic I focused on. I designed interviews to specifically assess the expected skills for a given position, reducing the false-positive and (hopefully) false-negative outcomes.
My usual environment:
- Java / SpringBoot
- RDBMs (MariaDB, PostgreSQL)
- Kubernetes
- Agile (Scrum, Kanban)
I have occasionally worked with others stacks (dotNetCore, Python...) and am ready to dive into any stack.
If you need a software engineer, I'll be glad to chat!
If you don't, would you share with me two people that may need one I could talk to? :)
