10 Years of Software Architecture: Best And Worst Decisions

For the last 10 years, I’ve been developing a single product, greenfield, designing the architecture from scratch, and evolving it over time.

Today, I want to share those experiences with you, diving deep into the good and bad decisions I made, and what I learned along the way. One theme that runs throughout my experience is the importance of isolation. How you isolate parts of your system, define boundaries, and manage dependencies can make or break your ability to evolve your architecture over time.… Read More »10 Years of Software Architecture: Best And Worst Decisions

CRUD APIs are Poor Design

I’m convinced that CRUD APIs and CRUD-driven systems—meaning systems built around Create, Read, Update, and Delete operations—are, in the long run, the hardest to change and evolve. This might sound unintuitive at first, especially since many of us have read blog posts, watched videos, or taken courses on building HTTP APIs under the guise of REST. But often, what we’re really doing is just CRUD-driven development over a database record using HTTP methods and JSON.
