How I Build Systems

Engineering principles I don't compromise on

The habits and defaults that shape every system I design, regardless of stack or deadline.

Design before implementation

Architecture decisions happen on paper first, so implementation is a matter of execution, not discovery.

Clear and stable API contracts

Interfaces are typed, documented, and versioned so downstream consumers can rely on them.

Reliable data modeling

Schemas are built to reflect real-world constraints, not just current feature requirements.

Performance with measurable reasoning

Optimizations are driven by profiling and metrics, not assumptions.

Security by default

Authentication, validation, and least-privilege access are built in from the start, not added later.

Maintainable architecture

Code is written for the engineer who maintains it next, including future me.

Production ownership

Responsibility extends through deployment, monitoring, and incident response, not just the pull request.

Simple solutions over unnecessary complexity

The simplest architecture that satisfies real requirements is the correct one.
