The situation

Commercial repellents work but carry safety and cost concerns for households. Whether a plant-based alternative actually performs was an open question locally.

What I built

We made the extract, tested it against a commercial product under the same conditions, and had twenty participants record what they observed. The results were then tested statistically rather than judged by impression.

Under the hood

The tools this is built with. You do not need to know any of them to use it — open one if you are curious what it does.

If you're considering working together

How a project actually goes

No jargon, no long contract to decode, and no stage where you are asked to approve something you cannot picture.

  1. 01

    We talk about the problem

    Not the software — the problem. What is slow, what gets forgotten, what people keep having to redo by hand. Usually one call is enough to see the shape of it.

  2. 02

    I write down what I heard

    In plain language, before any building starts, so you can correct me while it is still cheap to correct. You approve it or you don't.

  3. 03

    You see it early and often

    Working pieces, not screenshots or promises. If something is wrong, you say so while there is still time to change it.

  4. 04

    It goes live and stays supported

    Hosting, domain and setup handled. The Valley O'Ville site has been running since 2023 — I don't disappear after launch.

Have something in mind?

Tell me what is not working. If I'm not the right person for it, I'll say so and point you somewhere better.
