About

Hey,
I'm Kevin.

I'm a senior software developer based in Central Pennsylvania. I build web applications for people who have to actually use them every day — operators and clinicians who can't afford for the tool to be the problem.

Twenty-plus years of turning messy requirements into reliable software. I work across the full stack, from the Linux box up to the interface, and lately with a lot of help from the AI tools reshaping how we ship. Off the keyboard you'll find me in the workshop, in the yard, or somewhere in between — usually with a project half-finished and another one already planned.

What I do

Built across
the stack.

Full-stack web

PHP and MySQL are my bread and butter. I design the schema, write the queries, build the interfaces, and keep them fast under real load.

Multi-tenant architecture

Systems serving dozens of organizations from a single codebase. Permissions, data isolation, tenant-aware caching, and the audit plumbing that keeps auditors happy.

Regulated industries

Working context for HIPAA and 42 CFR Part 2 compliance. Immutable medical records, controlled substance workflows, audit trails that hold up under scrutiny.

Mobile & voice

Cross-platform mobile apps with React Native and Expo. Alexa skills on AWS Lambda with APL interfaces for Echo Show devices.

Infrastructure

Linux server administration end-to-end. Provisioning, hardening, deployment pipelines, and the dev-to-prod rsync workflows that make a one-person team feel like more.

API & integrations

Connecting systems that weren't designed to talk to each other. REST APIs, webhooks, payment processors, and document intelligence pipelines built on LLMs.

Experience

Where I've put
in the work.
