Custom Web App & System Development in Hong Kong
When spreadsheets, email attachments and chat groups stop scaling, we build the system: applicant portals, learning platforms, membership and booking systems, internal dashboards and admin CMSs — with proper roles, audit trails and automated tests.
What’s included
- Workflow mapping with your team before any code
- User accounts, roles and permissions
- Forms, file uploads, approvals and email notifications
- Admin dashboards, CSV export and reporting
- Payments (Stripe, FPS-ready flows) and third-party integrations
- AI features where they genuinely save time
Scope, costs & handover
Your proposal lists the pages or workflows, content you need to supply, review milestones and acceptance checks. Additional features are quoted before work starts.
Domain renewals, hosting, payment processing, AI API usage and other third-party fees are itemised where applicable. Ongoing maintenance is separate from new feature development. Code, accounts and operating notes are included in the agreed handover.
Common questions
Do you build systems from scratch or use templates?
We build on proven open-source frameworks (Next.js, PostgreSQL) and write the business logic for your workflow. You own the code and can host it anywhere.
How do you keep our data safe?
All reads and writes are checked on the server, passwords are hashed with modern algorithms, admin actions are logged, and we can host in Hong Kong. Our LMS for an education client is covered by around 2,300 automated tests.
