Experience
Percy
11/2018 - 5/2019
Senior Software Engineer, Infrastructure
- Prototyped and executed function as a service solution to prove out viability of rewriting browser rendering as a function, instead of a kubernetes backed rendering cluster
- Increased test coverage from ~10% to ~85% in a small, but critical HTTP Proxy project written in Go, resulting in more reliable and readable code.
- Acted as a team resource for Go knowledge and best practices, including test coverage, dependency management, and project architecture
- Wrote a kubernetes mutation controller to manage node taints, tolerations, and affinities for advanced cluster scheduling
Sensu
6/2017 - 10/2018
Software Engineer, Sensu-Go
- Collaborated on a team with 7 fellow developers on the open source sensu-go codebase, writing testable, reusable, and readable code.
- Removed operational roadblocks to help smooth out our development process.
- Enabled faster development, debugging, and release cycles by writing a terraform plan for a clustered staging environment on AWS
- Onboarded new engineers by walking through the codebase and pairing on feature development.
- Dug deep into etcd features, performance, and clustering.
- Notable accomplishments:
- Refactored keepalive and check ttl backend monitor code to ensure monitors were reusable and safely coordinated across a cluster of sensu-backend nodes.
- Implemented a durable, etcd backed queue for use with adhoc check requests.
- Paired with a colleague to plan, spec, rewrite, and reorganize sensu-go documentation. Revised language from a software developer focused, out of date reference, to operator centered getting started guides and complete api references.
