This web app was a whole new prototype for one of our customers at Global Resources. The customer’s domain was “Real estate”, and they wanted a new way to locate and promote sales.


We created this prototype based on the customer’s requirements (User Stories) providing deliverables every sprint. We used Scrum, and the development team was a front-end developer (me), a back-end developer, and a system administrator.


Requirements changed quickly, priorities shifted, we didn’t have a way to test the application with real users, and the CEO was providing solutions instead of formulating the problem.

My Contribution

My main contribution was making the interfaces easy to understand and easy to use (Inkscape + Code). Focusing on form validation, responsiveness, and quality of the product. Documented all the way while designing and coding, which helped me go back and re-use some of this work in future projects.

What we learn

  • The project, though not launched, was a significant learning experience for our team. Despite the considerable effort and time we invested, the decision was made not to proceed with the service. While this outcome was initially disappointing, it provided us with valuable insights and learnings.
  • One key takeaway was the importance of involving real users in the development process. While our CEO preferred a top-down approach, focusing primarily on a single stakeholder’s business vision, we recognized the need for user engagement to create more targeted and effective solutions. This experience underscored the critical role of user feedback in shaping a successful product.
  • On a positive note, this project was our first foray into using Ruby on Rails, and it quickly became a favorite framework among our team members. The skills and knowledge we gained in this area were not in vain. We were able to leverage our newfound expertise in Ruby on Rails to expedite development in other projects, benefiting a broader range of domains and customers.
  • In essence, while the project did not culminate in a launch, it served as an important stepping stone in our journey. It sharpened our focus on user-centric design and broadened our technical capabilities, both of which are invaluable assets in our ongoing work and future endeavors.
