Relevance

Why this case matters

This framing makes the decision signal explicit: impact, proof, fit, and AI / delivery relevance for hiring or collaboration.

System impact

Early real-world agile and Scrum context in a Java EE real estate portal with multi-tier architecture, TDD, pairing, and portal reengineering.

AI / delivery relevance

This is not an AI case, but it is an important delivery origin: small feedback loops, testability, and shared product work.

Especially relevant for

  • For teams that want to see agile practice before later leadership roles.
  • For organizations with classic enterprise systems that need maintainable product development.

Case context

Overview

Immonet's web-based real estate portal combined Java multi-tier architecture, complex development tasks, software ergonomics, and reengineering for better portal usage.

Scrum with user stories, sprint planning, retrospectives, and pair programming shaped the delivery work. Test-driven development, continuous integration, and code review supported quality; conceptualization, design, and forward-/reverse-engineering supported the architecture.

Technical context

Technology stack

The tools are not the point by themselves. What matters is which system layers had to work together.
