A bit about me

Engineer by training, builder by instinct — I love solving real problems with clean code.

William Friend

I'm a full-stack software engineer working remotely at Marathon Studios / AbuseIPDB — one of the internet's most referenced IP threat intelligence platforms, serving hundreds of thousands of daily requests from Fortune 500 enterprises to individual homelab operators.

Over the past 3+ years I've worn every engineering hat: full-stack feature development in Laravel and Vue.js, DevOps and server hardening with Cloudflare and Fail2ban, security engineering, data pipelines, and LLM integration. I own things end-to-end — from system design through code review, CI/CD, and production deploy.

I graduated from East Stroudsburg University with a B.S. in Computer Science (GPA 3.3) and have been building commercially since 2019 — first as a freelancer, then as a contractor, then as a full-time engineer. I'm currently building an IP abuse early-detection ML model and an AbuseIPDB MCP server for LLM agents.
