Experience

Senior Software Engineer (Remote) at Instructure

2016 - Present

Worked on 5 Clojure services:

  • Implemented core functionality of java interop with closed source vendor library (not easy).
  • Added set of shared query APIs (8 different views) with honeysql (super fun).
  • Added data migrations to deployment process to implement query optimizations.
  • Refactored test suite from unit tests to request specs to increase confidence in dependency upgrades.
  • Added metric collection, logging, and error handling middleware to provide consistency across services.

Created tools to increase productivity and lower barrier to entry for contributing:

  • Built open source CLI in Go to provide a simple, consistent workflow for local development including service configuration options, automatic loading of secrets, and programmatic access to configuration.
  • Utilized it in a variety of projects to enable coworkers of any team and role to get the projects up and running with ease (including CI build to reduce local dev breakage).
  • Built Ruby based super-project to stitch together multiple projects and ease cross-service development.

Worked on a feature team for 2 years using Ruby and JavaScript to implement and fix bugs in customer facing features; Moved to infrastructure/tooling team to focus on core backend features, tooling, testing infrastructure, and project architecture:

  • Added services to test suite to increase test coverage.
  • Built development/testing environments to better mimic production.
  • Created several linters and implemented test helpers for the QA team to use.
  • Fixed an awful lot of flaky tests to improve build speed and reliability.
  • Added features to C++ ruby gem to integrate app with Apache Pulsar.
  • Wrote ansible, terraform, and Dockerfiles to fix and enhance deployments.
