Backend & AI engineer — autonomous multi-agent systems, OAuth security, event-driven integrations.
I build systems that run without me in the loop: a multi-agent dev system that cut bug fixes from days to hours, the OAuth fix three services now run on. The point is leverage — the team doesn't have to work harder.

Backend platforms, autonomous multi-agent systems, and integrations work that lets one connector serve many.
Music & beats
I make beats and build the tools I wish I had to make them — producer software, audio in the browser.
Volleyball coaching
I coach volleyball, which is mostly the same job as engineering: read the pattern, coach the people, get the result.
Hardware
Hardware is where I started — Carnegie Mellon ECE, PCB design, and a soldering iron that still comes out. RLColor and Dabble live here.
The multi-agent system took bug fixes from 1–2 days to 1–2 hours at an 87% PR-acceptance rate. Re-architected integrations from 1:1 to 1:many — onboarding Facebook Lead Ads with no provider-specific code — and replaced polling with event-driven webhooks for 85% lower latency.
Killed session fixation across three OAuth services; that fix became the org-wide OAuth security standard.
A two-phase agent (authenticate → extract) built for financial-grade data handling. Credentials and PII are scrubbed with Presidio before storage; it uses Claude (Haiku) over MCP to get through 2FA. Local-first by design.
FastAPI + React/TypeScript with Stripe and the Claude API. It reorders and reframes real résumé content against the role you're targeting. The one hard rule: it never fabricates a line you didn't earn.
github.com/MParker25 ↗Made the CI/CD pipeline 98.6% faster across platforms, built an OTA firmware bridge from the Python backend down to Raspberry Pi modules, and stood up a Sphinx multi-language API docs portal so the hardware team could find the interface.
PHP, SQL, AWS, and Python scraping feeding a custom SuiteCRM. The pipeline ingested 1,000+ records weekly, and the cleaner data raised lead conversion by 20%.
A small, end-to-end browser audio extension at v0.1.0. Chrome & Edge. Installable today via sideload while the Chrome Web Store review is pending.

github.com/Mparker25/Crates ↗A coaching tool that organizes rotations, lineups, and per-rotation notes. It exists because the parts of coaching I love — reading a team, building a plan, coaching to a result — are the same instincts I bring to a codebase.

Led hands-on workshops on IoT and smart-home devices — the hardware roots, passed forward.
Full hardware product: ARM Cortex-M4 and nRF52840 on a custom Eagle PCB. Considered for a $75K AlphaLab Gear hardware grant — the PCB-to-production rigor that still underwrites how I build software.
