Hello, world — this blog exists

Notes from a senior engineer on pragmatic architecture, distributed .NET systems, applied AI, and operational decisions learned the hard way in production.

This is the first post of a personal blog I'll use to record what I learn building systems.

Why

I've been doing engineering for over a decade. In that time I've repeated decisions, re-examined trade-offs, and accumulated a few opinions — mostly about systems that keep working in production for a long time. This blog becomes the deposit for those notes.

What I'll write about

  • Pragmatic architecture: stack decisions, when to add sophistication and when not to.
  • Applied AI: how I use models in real products — no hype, no mystery.
  • Operations: what breaks, why, and how to make it wake you up instead of me.
  • Senior engineering career: hard decisions, partnerships, client vs. employer.

No fixed schedule. When I have something to say, it'll show up here.
