Things I've built

A game, a client product and an app my family uses every day.

Featured project

WaveLength

A browser puzzle game about signal processing. Players wire chips together to shape input waveforms into target outputs, and every solved puzzle becomes a reusable chip. Runs on a Canvas 2D engine written from scratch in TypeScript, built with Claude Code.

Result: Public beta with 6 puzzles and 1,300+ passing tests
Built with: TypeScript · Canvas API · React · Zustand · Vitest · Claude Code

Private client work

Tabula

A desktop app for building repeatable CSV workflows without code. Users compose typed rule blocks on a visual canvas to modify, exclude, or flag rows, see row by row why each value changed, and save every export as a replayable audit. Shipped to a client as a Windows installer.

Result: Shipped to a client as a Windows installer, built solo in four months
Built with: Electron · React · TypeScript · SQLite · Zustand · Mantine · Playwright

Three House Menu phone screens on a dark counter: the calendar feed of guest checks, an open meal ticket, and the grocery list

Personal project

The House Menu

A phone-first meal-planning PWA built for my household. Meals land on a calendar as diner guest checks, while a Postgres ledger tracks pantry stock, meal costs, and one shared grocery list that buys only what's missing.

Result: In daily use at home, backed by 133 tested database migrations
Built with: React · Vite · Supabase Postgres · Vercel Functions · Docker · Claude Code

Where I've built things that matter

Apr 2026 – Jul 2026
Remote
Software Engineer
Contract, private client
Designed and built Tabula solo, a desktop app that turns hand-edited CSV routines into repeatable, auditable workflows. Shipped to the client as a Windows installer, now in beta.
- Built a typed rule language with a visual block editor, three-valued logic, and per-row traces that explain every changed value
- Made every export replayable: snapshots, engine version, and a SHA-256 hash, with tests proving replays reproduce the original output
- Shipped with about 810 unit tests and about 60 Playwright scenarios that drive the real Electron app
- Kept a numbered decision log of 60+ entries through a mid-project pivot from single-purpose tool to general rule engine

Mar 2022 – Jan 2026
Seattle, WA
Front End Engineer II, Design System Platform
Expedia Group
Built and maintained React/TypeScript components in the Expedia Group Design System (EGDS), the shared UI layer every Expedia Group brand, including Expedia and Vrbo, builds its web experiences on. Rotated between brand-team support, maintenance, and feature pitches within agile teams of 3-5.
- Built and maintained core EGDS components, including the modal, calendar, and seat selector, where layout, state, and keyboard access all have to hold up at once
- As a designated Accessibility Champion, brought library components up to WCAG standards so every consuming brand inherited accessible defaults
- Built paired GitHub Actions workflows that ran a temporary EGDS build against the largest consumer's full test suite, catching regressions our own tests missed. Kept the signal advisory so flaky consumer tests never eroded trust
- Integrated a cascading design token system for customer theming, inheritance, and overrides, and built a Figma plugin that imports token values to keep designs aligned with the EGDS spec
- Built a Storybook playground plugin for building, saving, and sharing interactive code snippets, delivered in 3 days with AI-assisted development
- Embedded with brand teams on their sprints; unblocked Vrbo's crypto payment option with a team-owned component, then worked with head designers to promote it into the core library

About

From signal chains to software

Eric Chavez · Seattle area

I specialize in building shared UI component libraries and design systems at scale, writing clean TypeScript and shipping well-scoped work that teams can depend on.

My path to software started in music production. I studied audio engineering at Full Sail University and spent years arranging tracks in a DAW. I discovered that what I loved about music was the same thing I love about software: the way interconnected systems create something greater than the sum of their parts. The instruments started collecting dust.

After a coding bootcamp where I graduated top of my cohort, I spent nearly four years building design system components at Expedia Group, collaborating cross-platform with designers and engineers across web, iOS, and Android. Now I'm building with AI-assisted development tools and looking for the next team where I can make an impact.

Off the clock

3D Printing
I run a Raspberry Pi with Klipper and Mainsail to monitor and control my 3D printer, and print game miniatures and functional wall mounts.
Cooking
I cook, bake, and dial in coffee. Planning my family's meals is what led me to build The House Menu.
Hiking
I hike, camp, and ebike around the Pacific Northwest.
Music Production
Where it all started for me: a B.S. in Music Production and years of arranging tracks and signal chains in a DAW.
Video Game Design
I'm a lifelong gamer with an eye for mechanics and puzzle design. That curiosity turned into WaveLength's custom engine.
