Client: HealthTech Startup

A European-based healthtech startup focused on transforming how people access healthcare services. The company is developing a mobile platform for convenient interaction with healthcare professionals — from consultations to prescriptions — aiming to reduce the load on clinics and improve patient outcomes.

About the Client

The client sought to launch a mobile application that would serve as a comprehensive medical assistant in the user's pocket. The app needed to support remote consultations, provide access to medical history, simplify appointment booking, and ensure secure digital prescriptions and payments — all while complying with healthcare data regulations. The client lacked an in-house development team and needed a technology partner capable of delivering the full product lifecycle.

Project Overview

Challenges & Objectives

The team was tasked with developing a mobile-first, secure, and scalable solution that empowers users to manage their health remotely. Key objectives included:

Enabling real-time video and audio consultations with doctors.
Implementing secure sharing of images, documents, and videos for diagnosis.
Creating a digital prescription system integrated with pharmacies.
Providing online and offline access to medical records.
Developing an intuitive booking system with reminders and notifications.
Integrating secure and convenient payment methods.
Ensuring full compliance with healthcare data protection laws.
Strengthening application security through two-factor authentication and data encryption.

08

Applied OAuth 2.0 and 2FA to secure logins and protect sensitive patient data.

09

Ensured compliance with GDPR and HIPAA by adopting encryption, access control, and data retention best practices.
