Hi, I'm Jon Ruddell

Software engineer with a background in real-time video and high-scale backends, and a steady stream of side projects.

Most recently a Senior Principal Engineer in Vimeo's Office of the CTO, a five-year run that wrapped up with the Bending Spoons acquisition in April 2026. I'm looking for my next Staff+ or Principal IC role, consulting on the side in the meantime, and building side projects, most of them pointed at Winona Lake.

Projects & demos

Consulting

ConsultingAdvisory

While I look for my next full-time role, I take on a limited number of consulting engagements: full-stack builds, cloud and edge architecture, mobile apps, and technical advisory, with a growing amount of AI integration work. Clients have ranged from healthcare to auto sales, and I'm open to more.

Booray Cards

iOSAndroidWeb

A full cross-platform app (iOS, Android, and web) for playing and scoring the card game Booray. It's local-first: an on-device SQLite database keeps things instant offline and syncs to a Cloudflare Workers API. It handles user accounts and tracks the pot and each round as you play.

Winona Lake Conditions

Web appWeather

A fully server-rendered Cloudflare Worker that turns live Open-Meteo forecasts into go / marginal / no-go scores for lake sports (eFoil, wakesurf, wakeboard, and water ski) on Winona Lake. It weighs wind, gusts, rain, and daylight, and a scheduled job keeps the forecast cache warm.

Winona Lake Timelapses

AutomationVideo

An automated pipeline that captures the lake camera's RTSP stream and renders daily sunrise, sunset, and full-day timelapses on a schedule, then publishes them to a Cloudflare R2-backed gallery, with hundreds of clips archived and growing every day.

Winona Lake, 2025

Computational photographyData viz

A computational-photography recap of a full year of sky over Winona Lake. Roughly two million frames turned into sun-locked timelapses, star trails, keograms, and 'weather-removed' median videos.

eFoil Sync Companion

HardwareFirmwareWebMobile

A toolkit for Waydoo eFoil ride logs, built on protocols reverse-engineered from the board's own wireless traffic. A plug-in ESP32 sync box joins the board's WiFi after a session, pulls the new logs, and uploads them to a Cloudflare Workers backend, so the rides are waiting on your phone minutes later. A web and mobile app handles the maps, tracks, and stats.
