Case studies & system development

Custom web applications and selected case studies.

Move beyond standard templates and heavy solutions. As a freelance web developer in Copenhagen, I build custom systems where business logic, technical architecture and performance work together.

Sporting Health Club: Custom Staff Dashboard

BUSINESS CHALLENGE

Staff administration for more than 50 employees was handled manually in spreadsheets across 7 departments. This created data silos, administrative work for management and a high risk of human error.

THE TECHNICAL SOLUTION

A custom internal web application with role-based access for admins, managers and staff. The solution centralises data, supports approval processes and gives employees an intuitive mobile interface.

KEY FEATURES

  • Role-based permissions
  • Central data handling for 7 departments
  • Secure real-time data storage

PROCESS

  1. Map the spreadsheet flow and user roles
  2. Develop a central dashboard with admin, manager and staff access
  3. Create a mobile-friendly interface and shared data model for departments

CONSTRAINTS AND CONSIDERATIONS

  • The solution had to be simple enough for daily use by several user roles.
  • Data had to be centralised without making administration heavier than the existing setup.
  • The mobile experience had to work for employees who do not sit at a desktop.

TECHNICAL ARCHITECTURE

  • React-based frontend focused on fast workflows and clear roles.
  • Firebase as the data layer for central storage and real-time access.
  • A component structure that makes it possible to add new views and department needs.

MAINTENANCE AND NEXT STEPS

The next natural step is ongoing improvement of reporting, data views and role-based flows as real usage patterns emerge.

BUSINESS VALUE / RESULT

Full digitalisation: manual administration significantly reduced for 7 managers and 56 users.

Management gained one shared place for staff data, and employees gained simpler access to relevant information.

AS Web Solutions: Custom website from scratch

BUSINESS CHALLENGE

Attracting B2B clients for custom development required a solution without compromises. Standard WordPress templates were too slow and did not reflect the technical quality a freelance web developer should deliver.

THE TECHNICAL SOLUTION

A complete technical rebuild from scratch focused on fast loading, smooth animations, prerendered SEO content and a clean codebase without unnecessary plugins.

KEY FEATURES

  • Custom React frontend without template layers
  • Route-specific metadata and prerendering
  • Internal links to services and guides

PROCESS

  1. Positioning around custom web development and local visibility
  2. Develop a React-based website with a technical SEO foundation
  3. Continuously improve metadata, internal linking and conversion flows

CONSTRAINTS AND CONSIDERATIONS

  • The website had to explain custom development clearly without promising unrealistic SEO results.
  • The design had to feel technical and professional without looking like a heavy agency website.
  • The content had to balance local Copenhagen relevance with the option of remote collaboration across Denmark.

TECHNICAL ARCHITECTURE

  • Vite, React and TypeScript as a lightweight frontend stack.
  • React Helmet metadata, sitemap, schema and internal link structure for the SEO foundation.
  • Prerendering to make route-specific metadata and content visible in static HTML.

MAINTENANCE AND NEXT STEPS

The website should continue to grow with service guides, more case details and Search Console data as real search and conversion patterns emerge.

BUSINESS VALUE / RESULT

A faster, more focused foundation for local visibility and B2B lead generation.

The website works as a portfolio, local landing page and lead channel for new project enquiries.
