Frameworks change, but the hardest problems in production software don’t. This post explores what senior developers should actually care about in 2026 - judgment, boundaries, domain modeling, performance, testing, and communication - long after the hype fades.
Most engineering mistakes don’t come from ignorance—they come from good intentions applied too early. This post reflects on real-world trade-offs around abstractions, service layers, Clean Architecture, testing, and what I’d do differently today.
Stop writing C# classes that are just data bags. An anemic domain model scatters your business logic, leading to bugs and maintenance nightmares. Here’s how to fix it.
