I'm a network engineer who got into writing because the gap between vendor marketing and what actually happens at the edge of a real network kept bothering me. TravTeks is where I share what I've learned about the products and protocols I work with daily — Cloudflare, BGP, DNS, RPKI, network automation, and increasingly the humanoid robots that are starting to show up on production lines.

What you'll find here

The site is built around four areas I genuinely use and care about:

• Cloudflare — practical walkthroughs of WAF, Tunnel, Magic Transit, DDoS protection, and the rest of the product family. I run this site on Cloudflare Workers, so the bias toward Cloudflare is well-earned.
• Networking — protocol-level deep dives on BGP, RPKI, DNS, DNSSEC, MTU, and the operational stories that hide inside those topics. Includes post-mortems on real outages and hijacks.
• AI & Automation — using Claude and Cisco Workflows to automate real network gear. I'm interested in where AI fits into an existing operations workflow, not in pretending it replaces engineers.
• Humanoids — production milestones for Figure, Tesla Optimus, Boston Dynamics Atlas, Agility Digit, and 1X Neo. This is the one section that's not directly about networking, but the rate of progress is worth tracking.

Tools

I also build small interactive tools for the kinds of one-off questions that come up doing network work — BGP route lookup, subnet splitter, DNS propagation, SSL inspector, DNSBL checker, MTU calculator, and a couple of dozen others. They run client-side against public APIs, no account needed. If you find one useful or want to suggest another, let me know.

How I write

A few principles I try to keep:

• Hands-on first. If a post claims a workflow, I've actually run it. If I'm uncertain about something, the post says so.
• Cite the source. Every claim that comes from vendor documentation links back to the documentation. If a doc changes after I publish, I update the post and add an "Updated" date.
• Opinions are labeled. When I'm recommending something (like "skip the OWASP Core Ruleset"), it's marked as a recommendation, not as a fact.
• Corrections welcome. If I get something wrong, the fastest way to fix it is to tell me. I'd rather update a post than leave bad information out there.

Get in touch

The best way to reach me right now is via the social links in the footer below. If you've spotted something wrong in a post, suggested a tool, or want to compare notes on an automation project — I'd genuinely like to hear it.

TravTeks is built with Astro, hosted on Cloudflare Workers, written by a human (me), edited with the occasional second opinion from Claude. All code, content, and tools live in a public-ish repository on GitHub.
