Sean PeFull-Stack Developer

Infrastructure, clinical workflows, and the web.

I'm Sean, a software engineer in Houston. I built a FastAPI backend and the Python pipelines behind it for B2B clients at ConnectSys, and I now work inside a Baylor College of Medicine clinic, where I use Epic daily and build small tools for the physicians around me.

Off the clock I run a multi-node Kubernetes homelab under GitOps. Most of the infrastructure on my résumé was learned there.

About

I got into software through problem-solving, not through loyalty to a stack. The pattern repeats: find the friction, build the fix, hand it to the people doing the work. At ConnectSys that was an API server and data pipelines. At Baylor it's spreadsheets and clinic workflows that shouldn't need a human to retype them.

The homelab is where I learn infrastructure properly. A multi-node k3s cluster, Flux CD reconciling from Git, CloudNativePG, SOPS-encrypted secrets, and Cloudflare Tunnels plus Tailscale for access. When it breaks late at night it's mine to fix, which is the point.

Now: Front Desk Specialist, Baylor College of Medicine
Also: AI Trainer (software engineering), DataAnnotation
Looking for: Clinical systems / analyst or full-stack work inside a health system
Based in: Houston, TX

clinical tooling

IOL Calculator Automation

Batch-fills the ESCRS IOL calculator from a spreadsheet

A clinical research team at Baylor was hand-typing every eye measurement into the ESCRS intraocular lens calculator, one case at a time. This tool loads their existing spreadsheet, steps through it row by row, and fills the web form for them. The CAPTCHA and the submit stay in human hands on purpose, because that is where the automation should stop. Results are written back into the same sheet. It removed the manual data entry from the workflow and supported research the team has since published.

infrastructure

Kubernetes Homelab

A multi-node k3s cluster run the way production is run

A multi-node Kubernetes cluster that hosts my own services: this website, a PostgreSQL database, a media server, and local LLMs. Everything is declared in Git and reconciled by Flux CD, with Kustomize overlays per environment, CloudNativePG for the database, and SOPS-encrypted secrets in the repo. Remote access goes through Cloudflare Tunnels and Tailscale, so nothing is exposed directly. It exists so that I learn infrastructure by operating it, not by reading about it.

baccalaureate thesis

LUNA Doctor Recommender

Finds specialist doctors in the Philippines from symptoms and preferences

Finding the right specialist in the Philippines usually means asking around. LUNA takes a patient's symptoms and preferences and recommends a ranked list of specialists to see. I built the Vue.js front end and the Express.js backend, with a Python data pipeline behind them, and applied UI/UX principles to keep the interface usable for people who are not well. The application and research paper earned a 4.0.

Static Next.js on Cloudflare Pages

The site you are reading. A Next.js static export served from Cloudflare Pages, with no server to keep alive. The quotes on the front page come from a Notion page I have kept for years; a build-time script pulls them in, so the page stays static and the list stays mine to edit. A TypeRace toy lives at /race.
