How React and Redux brought back MVC and everyone loved it
Are we still talking about MVC? Isn't it dead already, with UML and waterfall? We want to soar through the cloud, create lambdas, use modern stacks, integrate with top-of-the-line libraries, the latest and the greatest — not something from a dust-covered book written a long time ago, in a galaxy far, far away. I hear you, young Padawan, but give me a few minutes of your time, and I'll explain how those two intersect, and how you can sit on the shoulders of giants.

Learning approaches for Angular
Angular has its roots in AngularJS, and many of the models from that initial framework remain relevant in the version we use today. Even with new changes like Standalone Components coming to the language, teams should be aware of the history and methodology at work here. Architects especially need to look for language features and anti-patterns that might trap their team and lead to performance bottlenecks in their systems.

GraphQL Performance Optimization
I recently joined a team in a great position - their GraphQL API PoC was green-lit to become the company's future platform and was nearing feature parity with their existing REST-ish API. As more product teams inside the company started building applications on the GraphQL API, the API team had to dedicate time to support, operations, bug fixes, and new features requested by product teams. Time for performance improvements was squeezed out, so I joined the effort to lower the server's response times and reduce resource usage with my fresh eyes and questions about everything.
