02 — Build

Websites that load fast, rank, and feed your automation.

Marketing sites, web apps and customer portals engineered for speed, accessibility and search — and wired so every form, event and conversation on the site can trigger real work behind it.

What this is

Three kinds of web build, one standard.

A brochure site, a logged-in application and a customer portal are different projects with different risks. What they share is the bar: fast on a mid-range phone, usable with a keyboard, structured for crawlers and answer engines, and instrumented so you can see what happened.

i.

Marketing sites

The public site that has to rank, convert and stay editable by your team without a developer in the loop. Clean information architecture, honest copy structure, schema markup, and templates your marketers can actually use.

ii.

Web applications

Software that lives in a browser: booking flows, quoting tools, internal consoles, member areas. Real state, real permissions, real error handling — not a static page with a form bolted to the side.

iii.

Customer portals

The place your customers check status, download documents, approve quotes, pay invoices and message your team without picking up the phone. Portals are where a surprising amount of support volume goes to die — and where an AI assistant has the cleanest data to work with, because everything the customer needs is already modeled.

What you get

The parts that decide the outcome.

01

Performance & Core Web Vitals

LCPINPCLSEdge caching

Speed is a budget, set before the first component is styled. We decide what the page is allowed to weigh, which fonts and images it may load, and how many third-party scripts it can carry — then hold the build to it. Most sites are slow for boring reasons: uncompressed hero images, a tag manager loading six analytics tools, and web fonts that block text from painting. We fix the boring reasons.

  • Performance budget agreed at design stage and enforced in the pipeline
  • Responsive images in modern formats, sized per breakpoint
  • Font loading strategy that avoids invisible text and layout shift
  • Edge caching and CDN configuration on Vercel, Cloudflare or your host of choice
  • Field data from real visitors after launch, not just lab scores
02

Accessibility & semantic structure

WCAG 2.2 AAKeyboardScreen readers

We build to WCAG 2.2 AA as the default, not as an upgrade. That means every interactive element is reachable and operable by keyboard, focus is visible, contrast is measured rather than eyeballed, form fields have real labels and error messages, and the heading order describes the page instead of decorating it. The same discipline makes the markup legible to search crawlers and to the language models now reading pages on a user's behalf.

  • Keyboard-operable navigation, menus, modals and forms
  • Measured contrast ratios across light and dark surfaces
  • Labeled inputs, described errors, and announced state changes
  • Semantic landmarks and heading hierarchy on every template
03

SEO-ready structure & CMS choice

Schema.orgSitemapsHeadless CMSRedirects

Rankings are earned by content, but they are lost by engineering. We ship crawlable URLs, correct canonicals, a real sitemap, structured data that matches what is on the page, and a redirect map that preserves every link you have earned. CMS selection is a per-project decision driven by who edits and how often — a team publishing weekly needs different tooling than a five-page site that changes twice a year, and paying for the wrong one is expensive in both directions.

  • Clean URL structure, canonicals and generated XML sitemaps
  • Schema.org markup for organization, services, articles and FAQs
  • CMS shortlisted and chosen with you — headless, hosted or none at all
  • Full redirect map from the old site, checked before cutover
04

Analytics instrumentation

GA4Search ConsoleServer eventsConsent

Most sites measure pageviews and call it analytics. We instrument the moments that matter — quote started, quote submitted, call clicked, document downloaded, checkout abandoned — and send them server-side where the browser is unreliable. Source attribution is stamped on the record at submission, so the lead that arrives in your CRM already knows where it came from and nobody has to guess later.

  • Event taxonomy defined with you, then implemented consistently
  • GA4 and Google Search Console configured and verified
  • Server-side event forwarding for conversions that matter
  • Consent handling that does not silently break measurement
  • Attribution stamped onto every lead record at the point of capture
How it connects to the AI layer

A site your agents can actually plug into.

This is the difference between a website and a front door. An agent is only as good as the systems it plugs into — and for most businesses, the first system a customer touches is the website.

05

Forms, events and clean handoff

WebhooksRESTn8nHubSpotTwilio

Forms post to an API endpoint, not an email address. Every submission lands as a structured record with source, timestamp, page context and consent state attached, then fires a webhook. From there an automation can qualify the inquiry, write it to your CRM at the right pipeline stage, and reply by SMS or email while the visitor is still on the page. Site chat runs on the same data your pages do, so it answers from real pricing and availability — and when it escalates, the human receives the whole transcript rather than a notification saying someone needs help.

  • API-backed forms with validation, spam controls and structured payloads
  • Webhook events on every meaningful action, ready for n8n, Zapier or Make
  • CRM writes with source attribution and correct pipeline placement
  • Chat and voice entry points that hand off with full conversation context
  • Content exposed through an API so agents answer from the live source

The last two weeks

Launches go wrong at the end, not the start.

A long DNS record, a staging password still switched on, a form nobody submitted from a real phone, tracking that starts collecting the day after go-live instead of the week before. These are the failures that follow a build, and none of them are design problems. We rehearse the cutover on a staging domain, run the redirect map against the live URL list, and stay on the first forty-eight hours.

The repository is yours from the first commit. Hosting, domain, CMS and analytics accounts stay in your name, and the handover includes the runbook rather than just the passwords.

How we work

From audit to live, without the drama.

Phase 01 — Audit

Measure what exists

We crawl the current site, check field performance, run an accessibility pass, and map where your leads actually come from and where they leak. You get the findings written down and a scope you can price.

30-min call · roadmap delivered
Phase 02 — Build

Design, build, review

Templates and components are built against the performance and accessibility budgets, with a preview URL for every change. You review real pages on real devices, not flat mockups.

Typically 3–8 weeks
Phase 03 — Launch & run

Cut over and watch

Redirects, DNS, certificates, analytics and monitoring go in before traffic moves. After launch we watch rankings, field vitals and conversion events, and keep the site patched and fast.

Ongoing partnership
Common questions

Before you ask.

Can you work with our existing site instead of rebuilding it? +

Frequently, yes. A performance and accessibility pass, a form and tracking rebuild, or a new template layer on top of your current CMS often costs a fraction of a rebuild and gets most of the result. We will tell you when a rebuild is genuinely the cheaper path, and we will tell you when it is not.

Which CMS will we end up on? +

It depends on who edits the site and how often. A team publishing weekly needs a proper editorial CMS with drafts, roles and scheduling. A five-page site that changes twice a year does not, and paying for one is waste. We shortlist two options against your editing reality, show you both, and you choose.

How do you handle Core Web Vitals? +

With budgets set before the design is finished, not fixes bolted on after launch. Image formats and sizes, font loading, third-party scripts and layout stability are decided during the build, and the pipeline flags a regression before it merges. After launch we watch field data from real visitors, because lab scores and real devices disagree more often than people expect.

Is accessibility included or an extra? +

Included. We build to WCAG 2.2 AA as a baseline: keyboard operability, visible focus, real contrast ratios, labeled form controls, sensible heading order and meaningful alternative text. It is cheaper to build in than to retrofit, it reduces legal exposure, and the same structure that helps a screen reader helps a crawler.

What does building for AI agents actually mean? +

It means every important thing a visitor does on the site emits a structured event, and every form writes to an API rather than an inbox. A submitted quote request can then trigger an agent that qualifies and replies in under a minute. Chat sits on the same data and hands off to a person with the full context attached.

Do you handle hosting and ongoing maintenance? +

Yes, and it runs in accounts you own. We set up hosting, DNS, certificates, monitoring and backups, then keep dependencies patched and performance inside budget on an ongoing plan. You can end that plan whenever you want and the site keeps running, because nothing about it depends on us.
