A clear step-by-step process builds confidence.
Users found it easier to work when the process was visible in one place instead of spread across separate files and emails.
Custom application

Summary
I designed and built a custom platform that replaces scattered files and email with one shared workflow.
The platform supports three main user roles and follows the way Planklaar already works.
Insights
Interviews and co-creation revealed three needs that shaped the design.
Users found it easier to work when the process was visible in one place instead of spread across separate files and emails.
Directors, project managers and advisors each needed their own information and actions.
Interviews and co-creation sessions uncovered missing steps, edge cases and moments where additional guidance was needed.

Prototyping
I mapped the process with the director, project manager and advisory teams.
Co-creation exposed manual tasks, pain points and exceptions. I used these to design role-specific structures and key flows, then tested and refined them with users.
After validating the Figma designs, I started in Lovable and moved to OpenAI, Claude and Cursor to build production-ready code, exploring multiple agents and models.

Testing
I tested the main flows with the people who would use the platform.
Daily workflows, labels, navigation and moments where users needed guidance.
Testing uncovered edge cases and areas that needed more guidance.
I refined the flows and simplified parts of the process before development continued.

Results
The new platform brings Planklaar’s permit process into one place. Teams have a clearer overview of their work, while each role gets the information and actions relevant to them.
