Case study · Team project · 2023–Feb 2025
ApolloMed Tech began as the final project of my degree and grew into an initiative with a product, architecture, brand, business plan and competition experience. Its aim was to give patients explicit control over who could see their health records.
The team completed and demonstrated the MVP, presented the project at FISTA and Junior Achievement Portugal, and received recognition in both programmes. That stage concluded after the competitions, while the underlying problem continued to shape my academic work.
My role
I led the planning and coordination of a six-person team. Alongside that role, I developed important parts of the Go solution: the web application, microservices, authentication and sessions, application integration with the Fabric network, and the administration interface.
Team effort
The solution was built by a multidisciplinary team covering project management, architecture, business, development, finance and marketing. This page separates my contribution without claiming the work of the other team members.
The challenge
Health records are often spread across different institutions and systems. Apollo proposed a way for patients to see their history, receive access requests from healthcare professionals, and approve, reject or revoke that access.
What the team built
Registration and authentication, profile, record wallet, access requests and control over active access.
Access requests, authorised patient-history views and professional profile management.
User management and visibility of service and network status.
A permissioned Hyperledger Fabric network modelling records and permissions between patients and professionals.
MVP architecture
The architecture evolved during the project. This view shows only the layers confirmed in the MVP and deliberately omits internal configuration.
Web application for patients, professionals and administrators · cross-platform mobile application
Go APIs and microservices · authentication · profiles · access · records
PostgreSQL for operational data · Hyperledger Fabric for the permissioned network
Services prepared for Docker containers and communication between components
My contribution
I organised the work, followed objectives and deliveries, and represented the project during presentations.
I worked on patient, professional and administrator journeys, including authentication, profiles, access and records.
I developed access and refresh token authentication, Go microservices and integration between the application and the Fabric network.
I created and evolved shared middleware for configuration, database access, localisation, logging, templates, requests and alerts.
Validation beyond the classroom
Ideas Competition at FISTA 2024, hosted by Iscte.
Presented by Banco BPI through Junior Achievement Portugal.
Patient, professional and administrator flows shown across web and mobile applications.
What remained
Project outcome
ApolloMed Tech moved beyond a degree assignment: the team built a web and mobile MVP, defined its architecture and business model, and presented the solution in two external programmes where it received recognition.
Continuation
The control, security and interoperability of health data remained important to me and influenced my master’s dissertation: “Secure Storage and Management of Medical Imaging in a Patient Wallet Using European Interoperability Standards.”
Technologies confirmed in the MVP
The original repositories remain private. They contain team-owned code, development configuration, synthetic clinical data and infrastructure details that are not required to evaluate the project. This case study publishes only approved, verifiable context.
