The situation

Inflation figures get reported as a percentage that means nothing on its own. Most people want the concrete answer: is my raise actually a raise, and what has my money lost?

What I built

Six calculators, each answering one question in pesos rather than percentages — purchasing power, salary, a raise, savings erosion, a wealth projection, and a timeline. They run on official Philippine price data. Every calculation happens on your own device: nothing is uploaded, and there is no account to create.

What it lets people do

  1. 01Check whether a raise actually beat inflation
  2. 02See what your savings are really worth now
  3. 03Track the peso's purchasing power over time
  4. 04Use all of it without an account, with nothing sent anywhere

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.

How a project goes
  1. 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. 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. 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. 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.
