For those that know me, you might have heard about my extensive use of Ionic Framework, a mobile app platform, to build various side projects including BrewZap and HappenZap. If you aren’t familiar with Ionic Framework, it’s a node.js based development...

If you have ever used Office Fabric with SPFx, you may have found yourselves struggling. You quickly learned than previous version of SPFx did not work with version 6+ of Office. Instead you had to use the LTS version of Office Fabric which varies significantly...

On any consumer-facing platform where users can submit content that will be seen by the public, it's a good idea to have some level of content moderation. Manual content moderation using humans is tedious and labor-intensive. Luckily, Azure Content...
