Problems solved

B2B websites become business systems once the work gets complex.

Established companies often outgrow the simple website model. Content depends on product data, sales workflows, approvals, regional teams, legacy CMS decisions, integrations, and internal ownership that has accumulated over years.

I work across those layers so the result is not just a better frontend. It is a website, CMS, and workflow foundation your team can operate and extend.

  • The website no longer reflects how the business sells or operates.
  • Marketing depends on developers for routine content and campaign changes.
  • Product, resource, and customer-facing content is spread across systems.
  • Several brands, markets, or audiences need shared infrastructure without losing control.
  • A rebuild or CMS migration carries SEO, migration, workflow, and ownership risk.
  • AI or automation would help, but the underlying knowledge and system boundaries are unclear.

Case studies that show the business problem behind the build.

These are not portfolio pieces. They are buying-context documents for leadership, marketing, and technical stakeholders who need to see the real problem, the internal tension, and the business leverage on the other side.

How a B2B Signage Company Uncovered a Growth Opportunity Hidden Inside a Website Project

A website consolidation brief turned into a strategic repositioning, multi-brand recommendation, buyer-led content architecture, and an AI-assisted lead qualification system.

Client
US signage and lighting company
Engagement
Website strategy, architecture, CMS implementation, migration, and AI-assisted lead qualification
  • Reframed four disconnected division sites into a buyer-led architecture.
  • Recommended a split-brand strategy instead of default consolidation.
  • Built a CMS and AI qualification layer the internal team could actually use.

//How I work

I stay close to the whole system: commercial context, content model, UX direction, implementation architecture, migration, launch, and stabilization.

Design collaboration with Katharina is available where the engagement needs stronger visual and interaction design, while I stay responsible for the technical foundation and delivery path.

See how I work

Complex projects start with clarity.

Before a large rebuild, migration, or consolidation, I map the current systems, content, workflows, ownership, and implementation risks. Smaller projects can move directly into a scoped build. More complex environments may begin with a dedicated Digital Platform Discovery engagement.

Specialist stack

Specialist implementation with Next.js and Payload CMS.

Next.js and Payload CMS are the implementation stack I use when the architecture calls for structured content, custom workflows, ownership, and long-term extensibility. Payload is not always the correct choice, but it is a strong fit when the business needs more than a page builder can safely support.

See how to choose a CMS
  • Structured and reusable content
  • Multi-site and multi-brand platforms
  • Multilingual delivery
  • Complex permissions and workflows
  • Custom integrations
  • Database and infrastructure ownership
  • AI-ready content access
  • Long-term extensibility

AI and automation create leverage when the system foundation is clear. I add retrieval, workflow automation, and internal tools where they connect to real business knowledge and operations.

//Questions clients ask before we start

What do you build?

Complex B2B websites, headless content platforms, AI-enabled workflows, internal tools, and integrations. The common thread is that the system connects customer experience, content operations, and business processes.

When do Next.js and Payload CMS make sense?

They are a strong fit when the project needs structured content, custom workflows, integrations, multiple sites or languages, and long-term ownership beyond a standard website builder.

Can you work with our internal team?

Yes. I can lead the entire implementation, build the platform foundation alongside another design or frontend team, or provide senior advisory while your internal team executes.

How does an engagement start?

Smaller and clearly defined projects can move directly into scoping. Complex rebuilds, migrations, and multi-system programs may begin with a paid discovery phase so the implementation can be estimated and sequenced responsibly.

Who is this for?

This is for you if

  • You are an established B2B company with a website that has become difficult to govern.
  • You are planning a complex rebuild, CMS migration, or website consolidation.
  • Marketing and operations depend too heavily on developers.
  • Several teams or systems own parts of the same customer experience.
  • Your internal team needs a clear architecture and implementation path.
  • You want one senior person connecting business, content, and technical decisions.

Not a fit if

  • You need staff augmentation or ticket-based execution.
  • You want a template rollout or lowest-price procurement.
  • You are looking for purely cosmetic work.
  • You want AI features without fixing the underlying system foundation.
