Joakim Lindberg is a senior web developer at Bryntum, based in Gävle, Sweden. He works on Bryntum Grid and Bryntum Scheduler, with a particular focus on lazy loading and time zone handling. Before joining Bryntum he spent eleven years at a Swedish software company, mostly as a full stack developer on a large web-based single page application built with ExtJS and .NET. He also worked there as a project manager, close enough to customers to work out what they needed and then deliver it, and spent his last five years in a CTO role leading the engineering department. That mix of hands-on development and delivery experience shapes how he thinks about component APIs.
