The product surface
- Medical document upload, organization, viewing, OCR, and assisted classification.
- Patient, dependent, family, professional, and company flows with distinct access responsibilities.
- Plans, payments, notifications, appointments, document sharing, and operational administration connected to the same platform.
Tg Apps responsibility
- Develop and evolve the Flutter applications across mobile and web surfaces.
- Build and maintain backend services, data flows, authentication, storage integrations, and product APIs.
- Coordinate changes across app and backend contracts, validate releases, and keep delivery moving as product rules evolve.
Delivery model
- An ongoing delivery relationship rather than a one-time prototype or isolated screen build.
- Product work that crosses mobile experience, backend rules, document handling, payments, and operational workflows.
- Direct technical responsibility with scope widened when the product needs more capacity or specialized work.
One platform serving different roles
Healthtech software becomes harder when the same product must respect different responsibilities for patients, family members, professionals, and organizations.
- Keep personal and company relationships distinct instead of treating every user as the same account type.
- Design document access and professional assignment as separate product decisions.
- Evolve the product without breaking existing patient and professional journeys.
Delivery across app and backend boundaries
The applications and backend services remain separate technical systems, but product changes need coordinated delivery across both.
- Flutter provides shared product delivery for Android, iOS, and web while preserving platform-specific release needs.
- Node.js and Express services coordinate product APIs, data rules, integrations, payments, and operational workflows.
- Firebase authentication and storage, OCR, assisted document classification, and external services are integrated according to each feature need.
Continuous evolution with clear boundaries
The work continues as DocVita grows, while repositories, environments, product rules, and release responsibilities remain explicit.
- New workflows are reviewed across application behavior, API contracts, data rules, permissions, and release impact.
- Production and validation environments support controlled delivery and investigation before broader rollout.
- Tg Apps supports the product as an active delivery partner while DocVita retains its product, accounts, data, and business ownership.
