Hey, I’m Maysen.

I write software for the web.

I work as an intermediate developer at Henry Schein One. I spend most of my time in Ruby on Rails and Ember, but I enjoy building with .NET and React.

Outside of work, I'm a triathlete and a helicopter pilot.

Projects

A few things I’ve shipped. The static site creator and Zwift workout editor are the larger ones.

  • ZWO Builder

    ReactTypeScriptCloudflareOpenAI

    A Zwift workout editor I built because clicking intervals together in-game is slow. Drag blocks around, describe a change in plain English, export a .zwo. Workouts stay on the the browser in IndexedDB.

  • Markdown website builder

    ReactTypeScriptCloudflareOpenAI

    Frontend pages from markdown, YAML frontmatter, and a bit of CSS, compressed into the URL. Share a link and the page renders — no accounts, no backend. The editor shows a live preview, and optional AI edits for an element or the whole page go through a Cloudflare Worker so the OpenAI key never reaches the browser.

  • URL shortener

    Ruby on Rails

    Rails redirect service with webhook-backed click counts. The interesting bit was keeping the hop itself cheap.

  • Link in bio

    Ruby on RailsHotwire/StimulusJSCloudflare R2 asset storage

    Link in bio app with an editable bio page. The app uses Hotwire/StimulusJS to update the bio page in real time. Links are orderable to prioritize the most important links.

  • This site

    AstroService Worker

    Personal site in Astro with a cache-first service worker. The project list is a JS file on purpose — adding something new should not involve a CMS.

  • Fake API

    Sinatra (Ruby)RESTful APIsJSON formatted responses from OpenAIagressive caching

    Sinatra app that stands up REST endpoints for testing. OpenAI fills in the responses, then they get cached so you are not paying for the same fake payload twice.

  • Planedle

    JavaScriptViteHTMLCSS

    A daily guess-the-aircraft game. You see a zoomed-in photo of a plane and each wrong guess zooms out, over six tries. Photos load from Wikimedia Commons.
