Work Experience
Data Engineer
2020 - 2022
Computational Physics
- Created, implemented, and maintained the data pipeline for several magnetometer sensor networks. Using Python, these pulled measurements from field devices over MQTT and stored the results in a TimescaleDB PostgreSQL database.
- Designed, implemented, and maintained the tooling for loading code and debugging remote magnetometers over OpenVPN and wrote several tools for automatic management of our OpenVPN deployments and certificate authority infrastructure.
- Maintained operations on featured at least three nines, 99.9% uptime, for all magnetometer services.
- Devised, implemented, and maintained a bottle.py webserver to allow end users to retrieve magnetometer measurements and status over the web. The API used an OpenAPI 2.0 (Swagger) schema, with JWT and API key support.
- Designed and maintained the PostgreSQL databases used for magnetometer measurements, managed operations, and tuned the databases.
- Maintained the AWS deployments for all of our services, specifically utilizing EC2, S3, and Simple Notification Service (SNS).
- Built, implemented, and maintained a general-purpose distributed job runner for several internal physics models and simulations, using PostgreSQL, Swagger, Python, and bottle.py, allowing users to upload, execute, and chain models.

Platform Software Engineer
2019 - 2020
NetApp
- Devised and implemented the transaction layer for a novel network management codebase using Python and SQLite, enabling custom two-phase commit behavior across systems for manual and timed rollbacks of network configuration.
- Implemented Ansible roles and playbooks to automate the SDS product deployment in customer environments.
- Designed and implemented the installation and management codebase for NetApp's software-defined storage product, using Python and Bash tooling to manage Docker in customer deployments and build RPM packages.
Technologies: Python, Linux, Docker, Bash, SQLite, SQL, RPM Packaging, Ansible
Software Engineer
2015 - 2019
SolidFire (acquired by NetApp)
- Implemented, maintained, and designed a bespoke visual programming language implemented in Scala, which featured a web front-end. This application allowed other developers to build tests and run builds for the Solidfire product.
- Handled operations and maintained four nine's availability for the above tool while in this role.
- Designed, implemented, and maintained a foreign function interface layer for the language, allowing developers to write and use Python functions and run them across many data centers.
- Created, implemented, and maintained Linux native isolation for the foreign function interface tool using cgroups, namespaces, and eventually LXC. The tool consistently ran thousands of concurrent Python instances safely on single systems.
- Designed, implemented, and maintained a Python hardware resource management and job coordination tool using Flask and the Connexion web framework, tracking tens of thousands of resources, and successfully scheduling access for many tools.
- Developed and implemented deployment tools using Fabric and Ansible, enabling single push-button blue-green deployments with rollback capabilities.
- Administered, designed, and tuned several Percona MySQL databases for the bespoke programming language system above. By the end of my role, these databases contained at least 6TB of production data, each with excellent performance.
- Designed, administered, and tuned a PostgreSQL database for the resource management system described above.
- Developed several other internal tools using bottle.py, Swagger APIs, and PostgreSQL to support other developers, including build tracking and API based alerting.

Firmware Engineer
2013 - 2015
Seagate
- Designed, implemented, and maintained the distributed test runner and reporting tool for Seagate's Kinetic network drive program. The system was implemented in Python with Erlang, C++, Java, and Python harnesses.
- Administered several self-hosted applications for test developers and other technical staff, including Redshift, Phabricator, and an IRC daemon.
- Designed and implemented an automated system and web application for code quality checks for SATA drive tests. The system used Python, Flask, and C, performed correctness checks, and linted code, sending regular email reports to test developers.
Technologies: Python, Java, Erlang, C, C++, Flask, SQLAlchemy, SQLite
Experience
Almost Home Resources App
https://ahra-beta.copesystems.com/This application allows the clientele of Almost Home, a homelessness prevention nonprofit organization, to search and browse various resources, such as low-cost mental health providers, dentists, and state programs. The application uses the Bulma CSS framework with Mithril.js for its front end, and on the back end, Python 3 with bottle.py and Swagger are used for the REST API. PostgreSQL is used for the database, and search utilizes PostgreSQL's built-in full-text search capabilities. The application is deployed to AWS's EC2 service.
