01Full-Stack Engineer

Sean

Senior full-stack engineer with over 4 years shipping production software end to end. I've built internal platforms, event-driven backend systems, and LLM/AI agent pipelines, owning each one from ambiguous requirements through to production debugging.

Most recently at Nettwerk Music Group through Springloaded, building a unified platform with LLM integrations in Laravel, React, and TypeScript. Before that with Steel Toad, an AI-powered scheduling optimization tool with Timefold in Spring Boot and Vue.js for ATS Engineers.

Academic background in biochemistry and jazz performance. Former Head Brewer and Production Manager at Strange Fellows Brewing: I'm passionate about my interests and I and see things through.

I'm at my best building with Laravel and React on a TypeScript foundation, and just as comfortable in Java and Python frameworks or a Vue.js frontend. Lately I've been deep in LLM API integration and agentic workflows, wiring up harnesses for AI-native development and tooling that holds up in production.

Live

Multi-protocol AV controller that unifies Roku TV, Denon/Marantz AVR, an HTPC, and a gaming PC into a single, locally hosted PWA.

  • Try the live demo linked above. On desktop you can watch the remote drive a set of virtual home-theatre devices in real time.
  • Scene presets: orchestrate every device in sequence, switching inputs, display resolution, and audio mode, then launching the app, all in a single tap.
  • Air Mouse: streams phone gyroscope data over Socket.io to move the HTPC cursor, with two-point couch calibration for accuracy from the sofa.
  • Custom Telnet driver: a persistent, auto-reconnecting connection that extends the limited Denon/Marantz HTTP API.
  • Cross-platform HTPC automation: a dedicated control path per OS, using EventGhost on Windows, ydotool on Linux Wayland/X11, and robotjs on macOS.
  • Installable PWA: add it from any browser on the local network, with a swipeable panel layout built for phones.

If you’re hiring, or you have a project that needs someone who can take it from idea to production and own the whole thing, I’d love to hear from you.

Always happy to talk through full-time roles, contract work, or collaborating on something ambitious.
