Hi, I'm Juan Noh,

Frontend architecture for a multi-tenant CRM. Component design and dynamic logic for sales and operations.

• ➜ Designed the frontend architecture and component system (Storybook), enabling dynamic multi-company configuration without touching code.
• ➜ Built complex POS and Surveys modules with reporting, replacing manual processes with automated digital flows.

Digital transformation of the sales channel: from an informational site to a transactional e-commerce.
