Senior Software Engineer specializing in building and maintaining scalable healthcare applications that help caregivers provide better patient care. I work primarily with Clojure, Python, and Vue.js to develop robust data processing systems and web applications from concept to production deployment.

My expertise spans the full software lifecycle with a strong focus on modern DevOps practices. I design and manage Kubernetes deployments for running applications at scale, implement CI/CD pipelines to ensure reliable deployment and application health, and build comprehensive monitoring and alerting solutions using Prometheus and Grafana. Security is paramount in healthcare—I actively identify and resolve CVEs to maintain secure, compliant applications.

Before transitioning to software engineering, I spent 8+ years as an astronomer, scripting and developing data analysis pipelines in Python for the James Webb Space Telescope's NIRSpec instrument. My research focused on Integral Field Spectroscopy (IFS/IFU) and Young Stellar Objects (YSOs), where I honed skills in rigorous testing, data processing, and scientific computing that continue to inform my engineering approach today.

Software engineering and development experience across healthcare technology and scientific computing domains.

Past and current projects that catch my attention, always with the intentions of learning more. The following projects, along with many other experimental ones, most can be found on my GitHub page.

dotFiles - My foray into creating a quick setup for my development environment. This is a fluid project, and will continue to evolve as I delve deeper. I currently use Bash as my environment of choice, as I've seen the least amount of setup problems with it.

astroplotlib - is a multi-language astronomical library of plots that serves as a template for producing paper-quality plots using IDL, Python, and Mathematica. This repo contains my Python script contributions to this project.

SendGrid Template Transfer - A Ruby script to transfer Sendgrid templates and their versions from one account to another. The process is automated by using the SendGrid template API.

Magic The Gathering Collection Services - Because I'm a geek! I recently stumbled upon an old collection of Magic The Gathering cards, and thought up an idea to build a collection tracking app from scratch. This is the beginning of my attempt, starting with creating a back end service to handle REST requests. This includes using services like Docker to stand up a detached SQL environment to test with, as well as the beginnings of managing the database in Amazon AWS. Follow along as I develop!
