01Full-Stack Engineer

Sean
O'Reilly

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.

ThriftyAI

A local control plane for coding-agent work that combines an integrated tracker with bounded orchestration, role-aware model routing, and project memory.

  • Integrated tracker: manage workspaces, projects, milestones, and tickets in one local board, then launch a run from ticket detail.
  • Bounded orchestration: deterministic workflow services keep scope, permissions, and test gates outside the model while the durable run graph exposes progress and recovery state.
  • Per-role routing: configure provider and model profiles, reasoning effort, fallback chains, and workflow presets for each agent role.
  • Budget-aware model routing: use frontier models for planning and review, then cheaper, faster models for routine execution; full budget tracking and enforcement are still in progress.
  • Skill manager: install, edit, version, and mirror repository guidance through an ownership-aware Skills UI.
  • BrainDB project memory: surface workspace-scoped roadmap, in-flight work, decisions, and claim health in a structured Brain view.

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.
