Principles
A short list of how I think about building software. Earned, not borrowed.
- 01
Simplicity is a feature.
The simplest design that solves the problem is usually the right one. Complexity should be earned, not assumed. Every abstraction has to pay for itself.
- 02
Reliability before cleverness.
Code that works predictably under load beats code that’s impressive in a demo. I optimize for the boring path being correct.
- 03
Measure before you optimize.
Intuition is a starting point, not evidence. I profile, look at the data, and fix the thing that actually matters instead of the thing that feels slow.
- 04
Maintainability is a kindness.
Most code is read far more than it’s written. Clear names, small functions, and honest documentation are a courtesy to whoever comes next — often me.
- 05
Security and testing are part of the job.
Not a phase at the end. Validating input, handling failure, and writing tests are how the work gets done, not an optional extra.
- 06
Consistency compounds.
Small, steady improvements outperform occasional heroics — in training and in engineering. Show up, ship, repeat.
- 07
Communicate the why.
A decision nobody understands is a decision waiting to be undone. I write down tradeoffs so the reasoning survives longer than the moment.
