// Active Work

Remote Ham Radio

CTO and Lead Developer

2013 – Present

As co-founder and CTO of RemoteHamRadio, independently developed, maintained, and supported the full-stack web application, associated hardware, and services.

The groundbreaking service for amateur radio operators provides voice communication and complex remote hardware control in a real-time browser dashboard, providing instant access to dozens of physical radio installations across the globe. In addition to product improvements, fixes, and deployments, I supported the day-to-day technical challenges, wrote documentation, and provided customer support.

Front-End

  • Vue.js
  • Electron
  • WebRTC
  • WebSockets
  • WebAudio
  • Canvas

The primary user interface is a Vue.js SPA that communicates with the back-end via WebSockets and RESTful APIs. WebRTC establishes voice and data channels to the remote locations, utilizing STUN/TURN servers to traverse NATs.

An Electron app for Windows and macOS provides customers with the ability to connect local software and hardware into the system.

Back-End

  • Phoenix / Elixir
  • Ruby on Rails
  • PostgreSQL

The mesh network of horizontally-scalable, hot-reloadable Phoenix servers routes WebSocket traffic between the users and the remote sites. Ruby on Rails provides the administrative interface for user account management. And it's all backed by PostgreSQL.

DevOps

  • EC2
  • ELB
  • S3
  • Route 53
  • CloudWatch
  • Grafana
  • Ubuntu

Web servers run on Ubuntu on AWS EC2 instances, load-balanced for performance and redundancy. Deployments are handled by Cloud66 and shell scripts, and metrics are piped to AWS CloudWatch and displayed in Grafana.

Hardware

  • Ruby
  • WebSockets
  • Circuit / PCB Design

Hardware control is implemented in a Ruby (non-Rails) application server, controlling dozens of different devices via serial ports, HTTP, TCP, and UDP.

Custom hardware was designed from the ground-up for use in-house and by customers.

Glance Networks

DevOps Consultant

2019 – Present
  • Packer
  • AWS
  • Azure
  • Python

Assisted the Glance DevOps team with the automation of building, deploying, and scaling of Glance server instances on AWS and Azure.

The legacy deployment strategy relied on hand-run shell scripts and manual version rollouts across multiple AWS regions. Packer was introduced into the build process, resulting in one-click builds of server images.

I worked with the Glance development team to create a RESTful API interface into their infrastructure, then used that API to build out autoscaling logic to automatically scale Glance server instances to meet load.

Does Not Compute

Podcast Co-Host

2018 – Present

Recorded over 100 episodes discussing various topics around software development, including news, conferences, languages, tools, learning, and the occasional off-topic tangent.
