Senior Developer
- Quality-driven lead/senior developer with deep experience mentoring
teams and
self-managing.
- Extensive freelance history has allowed me to develop the skills
necessary to marshall a project from proposal through implementation.
- Demonstrated ability to innovate "Why didn't I think of that?"
solutions to amorphous problems.
- Extensive Java, Python, SQL/ORM, and network application experience.
- DevOps experience working with AWS and docker containers.
- I am an avid problem solver. I enjoy puzzling through challenges,
whether they be programming tasks, infrastructure issues, or
architecture difficulties. It's embedded into my being and carries into
my personal life as well, from improving my swim stroke to solving
KenKens, crossword puzzles, and acrostics. I am intrinsically motivated
to complete tasks and refine solutions.

Experience
Senior Developer - Ocrolus, LLC,
February 2015 - April 2016 (Portland, OR)
Ocrolus, LLC - Software startup focused
on automating the process of reading and analyzing bank statements
Hired as a senior developer, my role expanded to also include
Security and DevOps.
Achievements include:
- On my own initiative, researched, proposed, documented, developed,
and implemented a novel solution using inheritable config files and
mustache templates to fix our code configuration issues that had
been plaguing the team for months.
- Transformed our ad-hoc deploy from an unreliable, unpredictable,
manual, error-prone, two-week process to a docker-based
single
script that worked across development, testing, and production.
Included in the deployment was:
- A flexible pip-based docker
deployment system that could
deploy from either branch heads or semanitcally versioned
git
tags, which pulled from 14 internal git repos and 69 pinned pip
repos
- A rollback system (both code and data)
- A data migration system (Alembic)
- A multi-docker machine log capture system
- HipChat notifications on success/failure
- Graceful diversion to maintenance pages
- Co-designed and implemented a Vault-based secret
management system
so we could remove secure data (AWS access keys, passwords, etc.)
from our code repositories
- Responsible for assessing security for our application, vpn, AWS,
email, and internal services
