Overview

This was my graduation project at Modern Academy: a two-application platform for a celiac patient association. One application handled association operations — inventory, appointments, insurance, and an e-commerce module — and the other served members through a mobile app. Both shared domain logic but exposed different APIs and access models.

Challenge

• Two applications, shared domain: the admin system and the member app needed different access models and API surfaces while sharing the same underlying logic.
• Wide feature surface: inventory, appointment scheduling, insurance processing, and e-commerce all had to ship under a single academic deadline.
• First time leading a team: I was responsible for backend architecture decisions, task delegation, and integration across four backend developers.

Solution

• Two-app architecture with a shared domain layer so the admin system and the member app could evolve independently without duplicating business logic.
• Role-based access control across both apps, with permissions defined centrally and enforced consistently.
• End-to-end delivery: architecture decisions, task breakdown, API design, and integration — graded Excellent by the review committee.

Lessons Learned

Leading a team under an academic deadline was the real education here. The technical work was well within reach, but coordinating four developers, agreeing on contracts, and integrating at the end without surprises was something I had to learn by doing. It is the reason I now default to writing interfaces and contracts before code.
