● Creating and interacting with GraphQL endpoints, defined via Rust code and interacted with in Elm, fully leveraging both languages' type systems.

● Safely managing data consistency in a Postgres database via managed migrations and a type-safe Rust ORM (2 actually, diesel and sqlx)

● Developing a web-accessible construction site tracking system, with drawing tools, photo upload and preview, and the ability to annotate drawn shapes with complex work tracking data and validate said data in Elm.

● Embedding self-contained elm modules within larger React codebases to improve performance, dev experience, and code re-use

● Cross-compilation of Rust code to WASM for embedding in Elm (experimental Lightning project to speed up web app)

* Developed integration test environments for large-scale, running systems controlling machine ordering

* Automatically generated test environments by inspecting the configurations of running services, correlating them with build target definitions, and recursively traversing program arguments describing endpoints of dependencies.

* Worked with remote teams to enumerate failure modes and potential misbehaviors of large systems

* Worked in an on-call rotation for the above service which allowed devs to generate test environments by providing a URL to their running service.
