I work on proxy and network infrastructure: Go and Python services, Linux networking, USB modems that need convincing, and the production systems that keep all of it running. ### Currently I'm building a browser and IP fingerprinting tool. ### At Proxidize I was a Senior Software Engineer at Proxidize from 2020 to October 2026. I built the first two generations of Proxy Builder as its sole engineer, then led the three-person team that shipped the third. All three were built by hand, before AI coding agents could write production code. In 2026 I worked on a self-hosted proxy router, a web scraping tool with its own stealth browser built on a patched Chromium fork, and an abuse-detection service that used ClickHouse telemetry. On those newer projects, I designed the systems and wrote the specs. Coding agents wrote most of the code, and I reviewed everything they produced. ### How I got here I studied computer science at Applied Science University in Jordan and worked briefly as a full-stack developer at 01 Inventions. A few months after graduating, I joined Proxidize to build the proxy platform from scratch. For the first few years, I handled Proxy Builder's development, testing, DevOps, and technical support. Working directly with customers taught me how the platform behaved in production. ### Outside work Three cats and a piano, which one of the cats has claimed. I go through a lot of tokens, and the number on this page is not a typo. I don't start anything before coffee. ## Work ### [Proxy Builder](https://bash.ar/work/proxy-builder) PROXIDIZE · 2020 – 2026 · WORK · 01 Self-hosted mobile proxy platform: customers run their own 4G/5G proxy networks on USB modems and Android devices. - **My role:** Sole engineer, Gen 1–2 · Led a team of 3 on Gen 3 - **Active modems:** 5,000+ - **Deployed servers:** 1,000+ - **Uptime, trailing 12 months:** 99.9% - **Stack:** Python · Django · Go · Bash · Linux · Postgres ### [Stealth browser](https://bash.ar/work/stealth-browser) PROXIDIZE · WORK · 02 A Chromium fork with the fingerprint patched in the browser's own source, and the Python CLI that drives it. ### [Proxier](https://bash.ar/work/proxier) PROXIDIZE · 2026 · WORK · 03 Self-hosted proxy router: one endpoint in front of every provider you pay for, with sticky sessions and automatic failover. ### CanTheyTell SIDE PROJECT · 03 · IN DEVELOPMENT Browser & IP fingerprinting.
