Backend APIs

I design and build backend APIs with clear contracts, validation, business rules, operational guardrails, and implementation detail that other engineers can inspect.

Evidence

Where to inspect this skill

Use these public examples and paths to inspect the parts of this skill that are easiest to evaluate. More specific skills narrow the evidence to one capability at a time.

Can lead and explain

The project shows enough structure, tradeoff reasoning, and explanation to evaluate leadership depth.

Professional context

Where I have used it

Across product and consulting work, I have built backend APIs in both C#/.NET and TypeScript/Node.js environments. The work usually combines contract design, validation, business workflows, persistence, integration boundaries, and operations-minded delivery rather than treating the API surface as a thin wrapper over data.
