Zachariah Leonard.
Software engineer, DFW
9 years. Web, mobile, CLIs, automation. Most of what's below is running in production right now.
01. About Me
I'm a software engineer in DFW. I've contracted at Microsoft and worked at Fortress Information Security and a handful of smaller companies, everywhere from enterprise platforms to a mobile app serving 20,000+ users.
Day to day I work in React, Node, TypeScript, and Python. Recent work leans heavily on AI tooling: local LLM pipelines, agent orchestration, and automation that actually holds up in production.
Off the clock I run local model setups and build CLI tools to automate whatever annoys me.

Game Hosting Platform
Full-stack multiplayer game server hosting with Kubernetes orchestration
A production-grade platform for deploying and managing multiplayer game servers. Users can spin up Minecraft, GMod, and Source Engine servers with one click, manage billing through Stripe, and control their servers through a real-time dashboard. The backend orchestrates containers via Kubernetes, handles automated backups to S3, and meters usage for billing.
Site Audit
Website security, performance, and quality scanner with honeypot-derived exposure probes
A web-based audit tool that runs 200+ checks against any website and produces a scored report covering security headers, SSL/TLS, exposure probing, accessibility, performance, SEO, and more. Enter a URL and get a full breakdown with per-category scores, letter grades, and actionable findings. The exposure scanner draws from a curated list of 120+ paths derived from real honeypot research (29,715 attack probes from 2,897 unique IPs), testing for .env leaks, exposed .git directories, admin panels, backup files, and Docker API endpoints.
