IT Systems Engineer · Fort Lauderdale, FL

Jon Pena

Systems engineer who writes the software. 7+ years as the sole or lead technologist for multi-site networks, Linux and Windows systems, Microsoft 365 and endpoint fleets, and the Python and JavaScript automation that ties them together.

Now building LLM tooling for operations: Zendesk ticket triage and an RMM troubleshooting agent. I isolate a fault to the layer it lives in, fix it there, and script the fix so it stays fixed.

Things I've built github.com/JPInert

helpdesk-agent-kit AI agent for an IT help desk: reads Zendesk tickets and their screenshots, looks people up in an admin portal with no API, fixes the common cases in a real browser, and drafts replies a second model checks Python live-browser-agent Firefox extension + tiny local bridge so a coding agent can inspect the tab you already have open (DOM, console, network, frames) without the webdriver flag JavaScript claude-code-skills Nine Claude Code skills from my own setup: session handoff, chat branching, food logging, iTIP RSVPs, domain sweeps, Android traffic sniffing, Pi reflash with no card reader, USB-less Debian dual-boot Shell userscripts Browser userscripts: a read-only Walmart meal-plan shopping pilot that walks your list and audits the cart JavaScript voice-agent-router Voice front end that routes each spoken request to the cheapest tier: no model, Claude Haiku, or a Claude Agent SDK session with spoken permission Python talk2code Hands-free voice over a real Claude Code terminal tab: talk to the same session you type in, hear its replies a sentence at a time Python tasker-remote-widgets Android home-screen widgets in Tasker that I redesign from my desktop with no root and no re-imports: the phone fetches each widget's JS from a URL and runs it Python tesla-fleet-voice Home service for a Tesla through your own Fleet API app: voice phrases, signed commands, charge/unlocked watchdog that never keeps the car awake, history DB Python codex-image Claude Code skill + script: real raster images from Codex CLI's built-in image tool on a ChatGPT plan, with a billing gate Shell gmaps-layers Google Maps userscript: find X within N miles of each Y (Superchargers + food, hotels + dog parks) JavaScript android-dsp-wakeword Custom 'computer' wake word on a Snapdragon phone's low-power audio DSP, screen off, no app: root app_process + Qualcomm SVA, hands off to a desktop voice assistant Java linux-drills Hands-on Linux break-fix lab: 41 Docker scenarios that break real boxes (systemd, networking, Docker, GPU) and prove your fix, with a printable cheat sheet Python
