Experience

I have worked across self-directed product work, industrial software, and client delivery. The common thread is turning messy problems into something useful and shippable.

A Few Things I've Built

These are the projects that best show how I think: product sense, frontend architecture, testing depth, and the ability to ship something real.

GlobePlay

I built GlobePlay as a 3D learning platform in Angular and Three.js. It renders 241 countries and GBIF migration data in real time, stays smooth on mid-range devices, and still works well when the internet is unreliable.

Why It Exists

It gave classrooms a globe tool they could actually rely on for exploration, quizzes, and progress tracking, even with weak connectivity.

Proof

241 countries rendered live · 407kB gzipped bundle · 60fps interaction / 0fps idle · <1ms GPU country selection · 604 tests

Stack

  • Angular
  • Three.js
  • WebGL
  • TypeScript

Richtext2Markdown

I built Richtext2Markdown in Angular to make rich text conversion feel simple and dependable. Accessibility was part of the build from the start, the output stays predictable, and the import and export flows hold up across browsers.

Why It Exists

It made writing and converting content less frustrating, especially for people using the keyboard or assistive technology.

Proof

6-browser validation matrix · keyboard-first accessibility baseline · deterministic conversion pipeline · performance-budgeted startup

Stack

  • Angular
  • TypeScript
  • Tiptap
  • Turndown

Independent Product Engineer

Talliofi

I built Talliofi as a local-first personal finance app where your data lives on your device first and sync is optional. The goal was to make budgeting and planning useful right away, without forcing account setup or default cloud storage.

Why It Exists

It let people start budgeting immediately instead of asking them to hand over data before they had even tried the product.

Proof

100% offline-capable default mode · 760+ tests · route-level code splitting · repository strategy for local and sync-ready storage modes

  • React
  • TypeScript
  • Vite
  • Tailwind CSS
