Griffin Hale Jack

Forward Deployed Engineer

Integrate legacy and third-party systems on site, build the tooling that makes the next run repeatable, and stay through rollout and support.

Experience

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.

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.

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.

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.

Built the missing layer over a repair shop’s API-less inventory, email and photo systems: bookmarklets, a Manifest V3 extension and a proxy/data backend. Used shop-wide daily for six weeks, until the vendor shipped the same features.
Ran rollout, documentation and support, with a build/live-mirror flow so non-developers could safely edit the deployed copy.

Reverse-engineered a legacy inventory app into nightly SQL ingestion over 30,000+ assets, reconciled two internal ID systems and scored every fact by source.
Shipped a vision-LLM identifier that names a part from a photo of its label.

Client engagement, concluded Aug 2026: integrated Meta Marketing, Microsoft Advertising, Google Ads and Search Console behind one adapter contract with recorded replay. Took the Meta reach lane from first contact to live in 202 markets in 12 days; wrote the credential runbook the client operates from.

Normalized six incompatible coding-agent log formats into one queryable SQLite schema for failure, token and workflow analysis.
