Cover image for Kalm is a clean, fast-loading
Kalm is a clean, fast-loading marketing website developed for a financial company that offers lease-like funding solutions to small businesses. The client needed a modern site that clearly communicates their services, builds trust with potential customers, and encourages conversion, all while staying minimal and performant. Our role was to implement the entire frontend from scratch using Next.js and Tailwind CSS, focusing on clean code, reusable components, and lightweight animations to elevate the user experience without overcomplicating the interface.
