Website Development

Website development is the design and technical build of a company's public-facing web presence, the platform, the pages, and everything running underneath them. Trellist builds websites for digital and IT leaders who need a site that performs technically, not just one that looks finished on launch day.

What we do

Custom Website Design & Build

Across major frameworks and CMS platforms, scoped to your actual technical requirements and content needs.

See the case study
Performance Optimization

Sites that load fast and hold up under real traffic, not just in a controlled demo environment.

Responsive & Accessible Design

Built to work across devices and meet compliance standards, including ADA and WCAG requirements.

CMS Integration

Connecting the front end to the content management system your team will actually use day to day.

See the case study
Ongoing Support

Continued development as the site and business evolve, rather than a one-time delivery that goes stale.

Our Approach

We start by understanding your goals, audience, and technical requirements. From there we architect the site's structure and experience, develop and test against real-world conditions, and maintain and evolve the site post-launch.

Signs You Need This

  • Your current site was built by a design-first agency with limited engineering behind it.
  • Page load times and performance issues have never been formally addressed.
  • Accessibility compliance is a known gap, not a confirmed strength.
  • The site hasn't meaningfully evolved since its original launch.

What You’ll Gain

  • A site that performs reliably under real traffic, not just in a demo.
  • Confirmed accessibility compliance instead of an assumed gap.
  • A site that keeps evolving with the business, instead of freezing at launch.
  • Engineering discipline behind the design, not just visual polish.

How It Compares

Trellist builds with software engineering discipline, testing against real-world load and compliance requirements. That's different from a design-only agency that hands off a visual comp without engineering rigor behind it, and different from a low-code website builder, which hits real limitations once traffic or customization needs grow.

Proof

We migrated multi-site CMS infrastructure to Azure for a global biologics enterprise, consolidating platforms and reducing operational complexity.

Frequently Asked Questions

What frameworks and CMS platforms do you build on?
We work across major frameworks and content management systems including AEM, Sitefinity, WordPress, and Shopify Plus.

Do you handle ongoing maintenance after launch?
Yes — most engagements include an ongoing support option so the site keeps evolving, not just shipping once.

How do you handle compliance requirements like ADA?
Accessibility is built into the development process from the start, with testing before launch, not addressed reactively afterward.

Can you work with our existing design system or brand guidelines?
Yes — we build within established brand and design standards rather than imposing a new visual direction.

Why Trellist

We build sites with engineering discipline, not just design polish.
