What it means to be a Senior - EMx 186
In this episode of the Mix the panelists talk about Seniority. They lay out their own personal journeys towards getting a senior title and how they define seniority for themselves - especially how it goes beyond the ability to write code well. Among other things they discuss: how to become fluent in reading and writing code how side projects are useful but not required to become a great developer how senior developers tend to approach problem solving and how to get better at that how interpersonal skills play at least an equal role as technical knowledge how specific tech know-how becomes less and less important the further developers climb the ladder - at least the managerial ladder how organizational structures cannot be ignored when building solutions They close with some picks which they deem valuable for anybody who'd like to dig deeper into some of these ideas.

How Quiqup Left Elixir and Then Came Back - EMx 183
In this episode the panel talks to Danny Hawkins - CTO at Quiqup - and his team's journey at Quiqup with Elixir. Danny explains how some of the first things Quiqup built were using Elixir and how they then left Elixir behind in favor of TypeScript, only to come back to Elixir.The panel considers how these choices rarely are purely driven by technological qualities but instead have to factor in cultural- and knowledge-aspects of a team, and how a top-down dictated technology decision - even if there are good reasons for it - can be harmful to a team's morale.Get in touch with Danny via email!
