Built score predictors for every major AP exam. You enter your estimated multiple choice and free response performance, and it predicts your AP score (1-5) based on historical cutoff data from released scoring worksheets.

AP exam season runs May through July — millions of students take these tests and then spend weeks obsessively trying to predict their scores before results come out. The existing options are scattered across ad-heavy sites or are outdated.

Also put together guides on which AP exams are easiest/hardest by pass rate and what scores you need for college credit at different universities.

All client-side, no signup, no data collection.


I built 50 cost calculators covering home improvement, automotive, dental, and other projects. Plain HTML, vanilla JS, CSS - no framework, no npm, no build step (well, one tiny Node script to inject shared headers). Hosted on Cloudflare Pages.

Each calculator takes your project details (size, materials, complexity) and gives a low/average/high estimate based on national pricing data from contractor surveys.

The whole site is ~230KB per page including fonts (self-hosted WOFF2). Every page scores 95+ on Lighthouse. No signup, no email gate, no lead-gen popups.

Stack: Static HTML + CSS + vanilla JS. One shared calculator engine (js/calculator.js) reads a config object on each page and builds the form dynamically. Total JS is under 4KB.

Built this as part of a solo dev revenue portfolio targeting low-competition SEO keywords. Happy to answer questions about the keyword research strategy, the build process, or the monetization plan.
