About this gig

Need a modern web application for your business or idea?


I build custom web applications that help you launch products, sell online, improve workflows, or turn ideas into working software.


What I can build:

  • Business and branded websites
  • E-commerce stores
  • SaaS products and MVPs
  • Customer portals and dashboards
  • Booking and membership systems
  • Internal tools and custom applications


What I can handle:

  • User accounts and authentication
  • Databases and data management
  • APIs and third-party integrations
  • Payments and business workflows
  • Custom functionality and backoffice features


For custom requirements, we will discuss your goals, priorities, budget, and timeline first. I will help determine what should be included now, what can be simplified or added later, and the best way to achieve it within the agreed scope.


For larger projects, development can be delivered in stages through a staging environment for review and testing before delivery.


I use Claude Code and Codex as AI-assisted coding tools to accelerate development, while personally reviewing, debugging, testing, and refining the code before delivery.


Please contact me before ordering to confirm your project scope.
