YEE YÔ — Commercial Management SaaS

YeeYo is a complete SaaS solution for commercial management (ERP/CRM): sales tracking, invoicing, inventory management, and point-of-sale system. Developed at BIACode, with Next.js on the frontend and Nest.js on the backend.

We progressed as a trio, **feature by feature**, rather than by technical layer: for each feature, I worked on both the Nest.js backend and the Next.js frontend as needed. I also set up the **CI/CD** pipeline and the project’s **Docker** containerization.

• **Frontend:** Next.js
• **Backend:** Nest.js
• **Containerization:** Docker
• **CI/CD:** automated deployment pipeline

An operational SaaS platform covering the entire commercial cycle—sales, invoicing, inventory, and POS—with an automated deployment pipeline that enabled the team to deliver rapid iterations throughout the project.
