Telemedicine app and medical backend for AlegraMED: video, chat and subscriptions

AlegraMED is an Argentine platform for digital medical consultations on a subscription model. It connects patients with specialists over video, voice and chat, and adds a digital medical record, emergency geolocation and a back office for medical centers.

The project started from zero, and that made the challenge strategic before it was technical: the job was to build a health platform ready to grow, not an app that worked.

• Three products, not one: a patient app, a specialist app and an administrative backend, all on the same ecosystem.
• Real time and healthcare: video, voice and medical chat demand low latency and security, and tolerate no downtime.
• Monetization by design: the Free and Premium model shapes the architecture, it is not bolted on later.

Getting the architecture wrong would not have cost a refactor: it would have meant rebuilding a medical platform with patients already inside.

We built the platform on a composable architecture, with the backend decoupled from day one so that growing would not mean rebuilding.

The work was organized around three pillars: architecture, mobile development with its integrations, and an experience designed for the medical context.

Composable, scalable architecture

• Decoupled backend and documented APIs, with an optimized relational model.
• Layered security, backups and monthly hardening as continuous maintenance.

Apps for patients and specialists

• Medical video and voice calls in real time, with two way chat.
• FIFO queue system with priority for premium users.
• Downloadable medical record, pill reminder with notifications and emergency geolocation.
• Native apps for iOS and Android, with Free and Premium subscription management.

An experience built for the medical context

• Social Login to cut entry friction, which in healthcare is where most users drop off.
• Guided onboarding and a direct emergency flow, with no steps in between.
• The medical record presented clearly, and a visible split between Free and Premium.

Administrative backend

• User, payment and medical center management from a web panel.
• Segmented push notifications and operational statistics.

Architecture and technology

• Infrastructure: AWS, with Lambda, RDS, S3, SNS and CloudWatch.
• Payments: PayPal and MercadoPago integration.
• Mobile: applications for iOS and Android.
• APIs documented in Postman, with multiple user roles.

Retention grew 40% and subscription conversion grew 25%, with waiting times down 30%.

Measured after the platform launched.

Starting point

• No owned platform: the service did not exist as a digital product.
• No subscription monetization model.
• Patients and specialists in separate circuits.

Results achieved

• 40% better retention: against medical apps with no premium model.
• 25% higher subscription conversion: the Free and Premium model is built into the product.
• 30% shorter waiting times: thanks to the priority queue system.
• 60% more repeat usage: measured across premium users.

Strategic impact

• Patients and specialists ended up integrated in a single ecosystem.
• The administrative back office covers users, payments and medical centers.
• The infrastructure scales without rebuilding the architecture.
