Experienced help for the digital work your business needs done

I'm Chris Abraham, and Gerris is my consultancy. I'm the person you call when the technical side of your web presence is a mess and nobody owns it. I find out what's wrong, write the plan, direct the developers, human and AI, ship what I can myself, and explain all of it in plain English.

I've built websites since 1994 and started Gerris in 2007. I'm based in Arlington, Virginia, just outside Washington, DC, and work with clients across the United States and the English-speaking world. Technical SEO is my deepest specialty and often how clients find me: crawling, indexing, site speed, Cloudflare, 301 redirects, Search Console, and migrations. Around that core I work as a fractional technical lead, write developer specs and check what ships, rescue stalled projects, and build small AI tools with Claude Code and Git.

When to call me

Nobody owns the website. You have a developer, a few vendors, and logins scattered across old inboxes. I can be your fractional technical lead.
Your developers need a clear brief. I turn vague complaints into specs with acceptance criteria and check what ships.
The project stalled. The freelancer vanished or the agency handed over a zip file. I handle rescues and takeovers.
You want AI to save your team time without new risks. I build small, safe AI tools with Claude Code.
Traffic fell off a cliff. I run technical SEO forensics and often find content the crawler never sees.
The site is slow or a migration is coming. See site speed and Cloudflare and migrations.
AI assistants get your business wrong. See AI search visibility.

Every service, from agency support to ecommerce, large sites, analytics, and email authentication, is on the services page.

How I work

Every engagement starts with a paid diagnostic: a defined question, the evidence, the cause, and a prioritized plan with an owner for each item. Then I make the changes I have access to, give your developers specs with acceptance criteria for the rest, and check the live result once it ships. Everything is in writing, in Basecamp or by email, with a technical document for the engineers and a plain-English summary for leadership. Details are on Work With Me.

Traced an e-commerce traffic loss to product templates that mounted specs, FAQs, and reviews only on scroll, which Googlebot never triggered.
Found a consent-management platform hiding every article's content from Googlebot on a WordPress media site.
Combined crawl evidence with an AI-assisted read of a Next.js repository to plan a clinical practice's migration off WordPress media hosting.

Directed the build of my own AI assistant with Claude Code: 9,600 lines, 106 tests, and safety rules on every action.
