The Case for Boring Technology and Maintainable Code
Why choosing simple, proven tools and writing code for the next reader leads to more reliable systems and happier teams.

I recently inherited a project that challenged how I think about technical choices. It used five different databases, two message brokers, and a custom framework, all for an application serving a few thousand users.
It got me thinking about the value of "boring technology": proven tools whose failure modes are well understood, so your team can spend its innovation budget on the problems that actually matter to the business.
Over three months, we consolidated onto PostgreSQL and a single queue, removed the custom framework in favor of well-documented open-source libraries, and added tests around every behavior before we changed it.
The results were remarkable: deployment time dropped from an hour to eight minutes, on-call incidents fell by 70%, and new engineers were shipping changes in their first week instead of their first month.
I now ask a few questions before adopting any new tool: "What problem does this solve that we can't solve today? Who will maintain it at 3 a.m.? How will the next engineer understand it?"
In our rush to adopt the newest thing, it's easy to forget that the most valuable code is often the simplest: code that's easy to read, easy to test, and easy to change.
