CIB Business Website - Kacper Kowalski

About the Project

Code repository is private due to client confidentiality

A collaborative 8-person team project building a fully functional business website with responsive design, product pages, contact forms, and client data export functionality. My role focused on design leadership, stakeholder analysis, and implementing interactive features.

Highlights

Led design across all pages with consistent visual identity and UX
Implemented client-side data export (multiple formats) using JavaScript File API
Built visual feedback system with form validation indicators and user action feedback
Ensured responsive design across desktop, tablet, and mobile using CSS media queries
Conducted stakeholder analysis to inform design decisions
Coordinated 8-person team across design, development, and QA phases

How it works

Multi-page business website with product catalog, contact forms, and data export. Users can browse offerings, submit inquiries, and export business data to CSV/PDF formats. Site is responsive and accessible across all devices with intuitive navigation and visual feedback on interactions.

What I learned

Team coordination: Git branches, daily standups, shared design documentation prevent conflicts
Stakeholder analysis reveals true requirements vs. nice-to-haves
Design consistency at scale: style guides and component libraries are essential
Client-side data export with JavaScript requires cross-browser testing and error handling
Responsive design testing across actual devices, not just browser dev tools

Next steps

Backend integration: replace static forms with database persistence
User authentication: implement account management for clients
Analytics: track user behavior to optimize conversion funnels
