About

Measure, understand, then engineer.

Lightcurve takes its name from astronomy, where a light curve records how the brightness of an object changes over time. It is one of the simplest tools in science, and one of the most revealing.

The scientific method

Evidence, applied to software.

Science doesn’t start with answers. It starts with careful observation, a testable idea, and the discipline to let the evidence decide. A single light curve can confirm a theory or overturn it.

We work the same way. Before changing a system, we observe how it really behaves. We form a clear hypothesis about what will improve it, measure the result, and refine until the data agrees.

  1. Observe

    Instrument the system and gather real data before drawing conclusions.

  2. Hypothesise

    State what we expect a change to achieve, and how we’ll know.

  3. Measure

    Test under realistic conditions, with load tests, telemetry and reviews.

  4. Refine

    Keep what the evidence supports, discard what it doesn’t, and repeat.
