What do you think about your current project or product? Boring? Innovative? "We don't have Kotlin, MongoDB, Kafka and GraphQL so I am wasting my time..." It's your feeling, but how about your project? Your team, organisation, customer - what is the best for them? We are not developing software just for ourself. During this presentation I am going to talk how to decide what is good for our product, what technology or technic we should pick, how to introduce (or not) new shiny pokemons to our project and how to validate if it really brings the value before we rewrite the whole codebase.
