Orion AI — Self-Hosted AI Chat Workspace

Open-source AI chat you run yourself—local Ollama by default, optional cloud providers, password-protected sessions, and conversation history kept on your machine. Clone, configure, and ship with one Docker Compose setup.

Private AI chat, zero SaaS lock-in

Next.js 16, TypeScript, Vercel AI SDK, and Docker Compose—JWT session auth, multi-provider routing (Ollama, OpenAI, Anthropic, Google), persisted conversations, and a guided setup flow. Open source and ready to self-host.

Orion AI — Self-Hosted AI Chat Workspace

Open-source, Docker-ready AI chat platform with local Ollama and optional cloud providers—password protected and fully yours.

Problem · Teams and individuals who want private AI chat without sending prompts to third-party SaaS need a setup that is easy to run locally, supports multiple model backends, and keeps conversation history under their control.

Solution · Built a dual-app monorepo: a Next.js chat client with JWT session auth, multi-provider routing via the Vercel AI SDK (Ollama, OpenAI, Anthropic, Google), and persisted conversations on disk. Packaged the stack in Docker Compose with bundled Ollama, automatic model pull on first boot, and a guided `/setup` flow—one command to clone, configure credentials, and run.

Tech n Rescue — Asset Intake & Repair Tracker

Full-stack web app for nonprofit tech repair programs (public GitHub reference implementation).

Problem · Volunteer repair programs need accountable tracking from device donation through repair to handoff—without spreadsheets siloed by role or lost audit history.

Solution · Implemented a Next.js App Router application with Prisma + PostgreSQL for a normalized device model, status workflow (intake → repair → distribution), and JSON APIs guarded by middleware. Added NextAuth credentials with JWT sessions, Zod-validated inputs, and RBAC (admin, volunteer, intake) enforced in API handlers—mirroring how real orgs separate duties.

PitotShield V2™ — Marketing & product site

Production web application for an aviation safety product (contract).

Problem · Stakeholders needed a credible, fast, media-rich site that explains a technical product to mixed audiences—operators, procurement, and partners—without a heavyweight CMS team.

Solution · Designed and built a modular Next.js + TypeScript front end with reusable layout primitives, static-friendly output, and asset strategies tuned for GitHub Pages–class hosting. Translated ownership feedback into shippable UI iterations and tightened perceived performance through image discipline and section-level code splitting.

Do Better Everyday

Native iOS habit-tracking app focused on clarity and daily use.

Problem · Users needed a lightweight, trustworthy daily habit flow without noisy UI or laggy state updates on older phones.

Solution · Implemented a SwiftUI client with async-friendly loading paths and a compact navigation model so the critical path (log → feedback) stays under a few taps. Structured views for maintainability as features grow.

About

I moved into software engineering from hands-on project management and IT operations. That background shaped how I work: clarify requirements early, communicate tradeoffs clearly, and ship incrementally instead of boiling the ocean.

I enjoy breaking down ambiguous problems—whether it's UI architecture, API boundaries, or performance—and turning them into maintainable code. I'm completing an M.S. in Computer Science at Clemson to deepen theory in parallel with production engineering work.

I'm targeting software engineering roles where I can own features end-to-end and collaborate with a strong product and platform culture.
