On-Demand Therapy Platform — Three-Audience Landing Layer

Wireframed, designed and then coded the public face of an on-demand therapy platform: three audience-specific landing pages — patient, practitioner and corporate HR — each built to reflow across three breakpoints. This is the landing layer only; the product behind it is another designer's work and another team's build.

Field-Service Operations Product & Marketing Site

Designed an eight-module operations product for a technical-assistance business — service desk, quoting, a work-order kanban, catalogues, customers and finance — then designed and coded its marketing site in Next.js. The product is live in production; a later team rebuilt it on a different stack, keeping the design.
