Clojure in Product. Would you do it again?

Welcome to the 10th episode of our podcast, "Clojure in product. Would you do it again?", where Artem Barmin and Vadym Kostiuk speak with Cam Saul, Chief Architect at Metabase, an open-source business intelligence platform. In his role, Cam wears multiple hats, including reviewing architectural documents, managing developer tasks, and writing custom linters to ensure code quality.

We discuss the integral role of Clojure in Metabase's development and how transitioning from Python allowed the team to ship features much faster. Cam also shares insights into the blend of Clojure and JavaScript developers, highlighting the advantages of Clojure's stability, which enables the team to build upon existing work without the frequent changes seen in other programming environments.

The open-source foundation of Metabase has fostered a collaborative culture that attracts external contributors, some of whom joined the team after submitting valuable requests. Cam reflects on the journey of hiring Clojure developers, emphasizing the learning opportunities it provides. We conclude with Cam's thoughts on the Clojure community and his response to a question from our previous guest, Alexander Johannes from JustOn.

In the 9th episode, we welcome Alexander Johannes, Head of Development at JustOn, a German fintech company specializing in developing Salesforce accounting solutions since 2010. We discuss the nuances of building software for the AppExchange marketplace and the significance of Clojure in niche markets.

What started as a hobbyist's passion for solving intriguing problems like parser development has evolved into the full integration of Clojure into the tech stack, laying the foundation for JustOn's current projects. As Alexander noted, "It opened up the possibilities to be faster and deliver something meaningful."

Learn how JustOn's development team, under Alexander's leadership, developed and maintained the backend in Clojure, including business logic, mass data transformation, and platform integrations. We also walked through a series of questions about project structuring, software testing, hiring practices, overengineering, and team culture. When asked, "Would you choose Clojure as the main tech stack for your next product?" Alexander confidently said, "I would say yes," emphasizing their experience as underdogs in a niche market and the advantages that Clojure provides compared to mainstream technologies like Java.
