Griffin Hale Jack

Software Developer | Python, JavaScript & Interactive Tools

Build full-stack applications and interactive tools, from domain research and architecture through documentation, deployment and user support.

Experience

Founder · KnownBetter Studios, LLC

2026 – Present · Portland, OR

  • Develop games and software with user experience and reliability guiding product design and architecture.
  • Study past and competing architectures, including where they fall short. Experiment within domain constraints to balance performance, simplicity and user control. Document decisions and verification limits; use CI to catch generated-code drift.

Freelance Software Developer · Silicon Forest Solutions LLC

Aug 2026 – Present · Portland, OR

  • Built a FastAPI/PostgreSQL system to assess opening a practice, integrating Meta, Google Ads, Microsoft Advertising and Search Console with replayable adapters and PDF reports explaining platform limitations.
  • Built a Django drum-studio scheduler with database-enforced double-booking prevention and a ledger tracing every lesson owed.

Embedded Systems / Ultrasound Repair Technician · Sonovision

Jan 2025 – Aug 2026 · Portland, OR

  • Diagnosed mechanical, electrical and software faults across 60+ ultrasound machine models. Flashed locked-down boards and recovered hardware beyond standard repair procedures.
  • Automated expert-only hardware recovery in Python and Rust, making procedures repeatable and verifiable.
  • Built nightly SQL ingestion for 30,000+ assets, order-entry browser tools and a Dockerized label service used daily by 12 staff; led rollout and support.

Food Service and Hospitality

2016 – 2023 · Portland, OR

  • Alongside food service, briefly ran a recording studio across two spaces before returning to school, working with local youth music organizations to provide free or low-cost recording and audio engineering.

Selected projects griffinhale.com/projects

Catlg · TypeScript · React · React Native · Fastify · PostgreSQL · catlg.app

  • Unifies books, games, music and film with shared collections and recommendations. Integrates 9 metadata providers and 18 library connectors while preserving user records and flagging uncertain matches.
  • Share query logic and design tokens across web and mobile; generated API contracts and drift tests keep clients consistent.

Permit Office · Python · arcpy · Tkinter · github.com/Griffinhale/permitOffice

  • Turned ArcGIS Pro into a city-management game: map selections and geoprocessing drive a 12-week simulation. Test rules and seeded runs without a licensed host; publish code, decision records and a changelog under MIT.

cabinFever · JavaScript · ESM · Canvas · github.com/Griffinhale/cabinFever

  • Built a browser paper-marbling library producing 17 traditional patterns through mathematical transformations that preserve boundaries under stretching. No dependencies or build step; property tests and seeded output ensure reproducibility.

And More Will Follow · C11 · Swift/SwiftUI · iOS · watchOS

  • Prototyped a tile-to-idle-city game in Godot, then moved its simulation to portable C. A heap-free renderer and 532-byte watch snapshots support constrained hardware; native shells handle input, rendering and accessibility.
