Informazioni su questo servizio
Need software built specifically around your business, workflow, or idea?
I build custom web applications, SaaS products, internal tools, dashboards, portals, and database-backed systems.
Projects can include:
- SaaS applications
- Internal business tools
- Customer and employee portals
- Dashboards and admin systems
- Database-backed applications
- Authentication and user accounts
- Subscription and payment systems
- API integrations
- Workflow automation
- Search and data tools
- AI-enabled applications
- Existing application improvements
My development experience includes technologies such as Next.js, JavaScript, TypeScript, Python, Supabase, PostgreSQL, APIs, cloud infrastructure, and AI systems.
You do not need to arrive with a technical specification.
Tell me what the application needs to accomplish, who will use it, and how the workflow should work. I can help translate that into a practical technical solution.
Please contact me before ordering Standard or Premium projects so we can confirm scope.

I'm Constantine, founder of XRTech in Honolulu. I build AI-powered software, VR/AR apps and websites, and I help small businesses find the government funding to pay for them.
8+ years shipping Unity apps for Meta Quest, Apple Vision Pro and HoloLens, plus deep learning and full-stack web. I add LLM features to existing products, build WebXR that runs in any browser, create 3D/CAD models, and handle SAM.gov/SBA registration, grant research and SBIR proposals with my own contracting tools.
Send me your idea and I'll reply with a plan.

FAQ
Can you build the entire application from scratch?
Yes. I can handle frontend development, backend systems, databases, APIs, authentication, integrations, and deployment depending on the project.
Can you continue an application another developer started?
Yes. I can review an existing codebase, add functionality, fix problems, or continue development.
Do I need designs before contacting you?
No. A description, sketches, examples, or even a clear explanation of the workflow can be enough to begin planning.
Can you build AI features into the application?
Yes. AI and LLM functionality can be included when appropriate.
