Light Switch AI
Technology

AI as an engineering discipline

We don't ship vibes. Our systems are versioned, evaluated against real data, and transparent about their limits.

Engineering principles

Measured, reproducible, swappable

Versioned everything

Models, prompts, and configs are versioned like code. Every result can be traced back to exactly what produced it.

Swappable backends

We keep a clean interface between our products and the underlying models, so we can run hosted or local — and switch as needs change.

Evaluated before promotion

Candidate models are scored against labeled data. Nothing reaches production unless it measurably beats what's already there.

Structured & honest output

Schema-enforced results with confidence and clear limits, so downstream systems — and people — know what they can rely on.

The stack

What powers Light Switch AI

A modern, boring-where-it-counts stack: React on the front, C# on the back, models in the middle, all on Azure.

Next.js + React

Fast, accessible, SEO-friendly web experiences.

.NET / C# APIs

Backend services built on ASP.NET Core minimal APIs.

AI models

Hosted and local models behind one provider-agnostic interface.

Versioned data

Labeled datasets with provenance that power continuous evaluation.

Azure

Containerized services on Azure App Service, fronted by a CDN.

Spec-driven CI

Every feature ships from a spec, with tests and a passing pipeline.
