Apprenticeship at Busit SAS

I joined Busit SAS as an apprentice, working within a small technical team composed of two apprentices and one developer. The development environment lacked essential tools to improve code quality and developer productivity. Upon my arrival, a critical factory monitoring application had just been deployed, driving the need for product industrialization and improved deployment processes.
