About

I've been a professional software engineer since 2006, spending the majority of my career in the field of astrophysics. I've recently started my own company, Moriarty Engineering LLC , to pursue my own endevours. I'm passionate about science, technology, and the intersection of the two. I'm always looking for new and exciting opportunities to collaborate with others!

Experience

  1. April 2025 — Current

    I designed and shipped a series of end-to-end software and hardware projects spanning embedded systems, full-stack web development, infrastructure, and game development. Highlights include building an ESP32/CircuitPython system that delivers real-time subway arrival data to an LED matrix display; creating and self-hosting a web comic platform using Svelte and PM2; architecting and operating a personal virtualization lab with 20+ VMs and 40+ containers to securely provide open-source alternatives to common cloud services for friends and family; developing a real-time location-aware web application for Somerville Porchfest 2025; and releasing a small cross-platform game built with the Godot engine. Collectively, these projects demonstrate strong ownership, systems thinking, and the ability to take ideas from concept through deployment and real-world use.

  2. October 2024 — April 2025

    Part time contract to build out a second physical site for backup and disaster recovery. I designed, built and deployed the primary virtualization system to migrate off of old poorly maintained IT infrastructure. I chose to use XCP-ng and Xen Orchestra, and a high speed SAN for shared storage across the hypervisors. All of which is integrated with full system monitoring solution based on prometheus and grafana.

    Developed a Docker-based framework for hosting public facing React based web content and Python APIs using Flask, with fast access to a replicated operational database. Reorganized management of the team by dividing operations and software development into separate workflows, leveraging Jira Service Desk and Jira Software Cloud. Wrangled many disparate code projects into a structured mono-repository, building a software development process around feature branching and pull requests using Github. Hired and directly manage two junior software engineers. Mentored an intern to develop a Near Earth Object classifier using TensorFlow.
