Doutor na Net: affordable telemedicine on a micro-frontend architecture

Context and problem

In Brazil, private consultations are expensive and the public health system has long queues. Low-cost clinic chains such as Amor e Saúde proved there is a large audience willing to pay less for fast care — but still in person, depending on travel and opening hours.

Doutor na Net took that model to telemedicine: patients pay less for consultations, one-off or on a plan, and see a doctor by video call from wherever they are, with digital prescriptions and history in the app.

The app is no longer live, but the project shows an end-to-end build of a digital health product.

My responsibility

• Flutter specialist through Devvo Tecnologia.
• Feature development and ongoing maintenance of the app, including video calls, payments and digital prescriptions.

Solution

Flutter app with a complete purchase flow: choose a one-off consultation or a plan (e.g. Individual Telemedicine), confirm payment method, type and validity, pay and access the consultation.

A “My contracts” area to track active plans, video calls for consultations and digital prescriptions.

Architecture decisions

• Micro-frontend architecture: each area of the app (purchase, payment, consultation, contracts) as an independent module, so parts of the product could evolve and be maintained without affecting the rest.
• Flutter to ship Android and iOS from a single codebase.

Stack

• Flutter
• Dart
• Video SDK
• Payments Integration

The low-cost clinic model brought to telemedicine, with cheaper consultations and no travel
