Problems solved

The business problem comes before the technology.

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 connected website, CMS, application, data, and workflow foundation your team can operate after launch.

  • 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.

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.

//The people who define the system build it.

Matija translates the business requirement into architecture, full-stack implementation, integrations, infrastructure, migration, and production delivery. Katharina turns the same system into a clear user experience where the engagement needs deeper UX and interface design.

AI accelerates implementation. Architecture, data ownership, permissions, workflow behavior, security, acceptance criteria, and production responsibility stay with the senior team throughout delivery.

See how I work

Years of technical learning, compressed into your project.

The architecture is informed by systems already built, broken, recovered, migrated, secured, and operated across databases, hosting, migrations, permissions, queues, caching, CMS architecture, security, and backups. Clients avoid learning those lessons inside their own production environment.

Explore Digital Platform Discovery

Specialist stack

A focused technical foundation for modern web platforms.

The technical focus is modern full-stack JavaScript: Next.js, Payload CMS, TypeScript, Node.js, PostgreSQL, headless CMS platforms, hosting, queues, caching, storage, CDNs, integrations, multitenancy, permissions, migrations, and production operations. The stack proves capability after the buyer value is clear.

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 increases delivery capacity when senior judgment stays in control. I use AI to move faster through interfaces, integrations, migrations, application logic, infrastructure configuration, tests, and documentation while keeping architecture and accountability human-owned.

//Questions clients ask before we start

What do you build?

Connected digital platforms for B2B companies: complex websites, content platforms, AI-enabled workflows, internal tools, migrations, integrations, and infrastructure. The common thread is that the system connects customer experience, content operations, data, 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. They confirm implementation capability; they are not the reason to start the engagement.

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 direct access to the senior people connecting business, UX, data, application, and infrastructure 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.
