Featured Case Study

From Simple Monolith to Secure Exam Platform

How we evolved Wolfmed Edukacja's medical exam system from a 2-tier MVP to a secure, scalable architecture.

Challenge

Evolve a simple MVP into a secure, compliant exam platform capable of handling timed assessments.

Solution

Introduced lifecycle-based domain design with test_sessions and completed_tests tables — enabling fairness, auditability, and scalability.

Outcome

Clear domain boundaries and DDD principles prepared the system for 3-tier and eventual microservice evolution.

"You don't need microservices from day one — just design with tomorrow in mind."

Architecture Evolution

🏗️

MVP:

Next.js (UI + Logic) → PostgreSQL

🧠

Refactor:

Added test_sessions + completed_tests

⚙️

Future:

Express API + React UI + DB service (3-tier)

☁️

Scalable Path:

Modular → Microservices-ready
