The situation

Practice material for this exam is either expensive or slow and cluttered. Someone studying after work wants a question, an answer, and the reason behind it — quickly.

What I built

I built a stripped-back study site: 400-plus practice questions, each with an explanation of why the answer is right. There is a multiplayer mode with live scoring and a leaderboard for people who study better against a friend. Everything runs in the browser, so it stays fast and costs almost nothing to keep online.

What it lets people do

  • Work through 400+ practice questions with explanations
  • Compete live against another person, with scores and a leaderboard
  • Study from a phone, with no account and no download

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.
