In episode 40 of UTVECKLA, we dig into dependency injection together with Mikhail “Mike” Artemev, software engineer at Truecaller. Mike tells us about a massive migration project that he has been part of at Truecaller, why dependency injection was such a useful technique for that project, where Hilt and Dagger come into the picture and what challenges he has had to deal with along the way. Mike also explains the Hollywood principle of dependency injection and gives his recommendations for those who are considering a migration project of their own. The interview part will be in English.
