Multitier Application | Bridging the Gap Between Designers and Developers

A MERN stack-based application for bridging the gap between designers and developers to increase productivity and decrease time to market. The application consists of a customer-facing React web application, on-premise back end, database, and Figma plugin on the designer side.

I was actively involved in these activities:
• Conducting research and spikes to choose technologies.
• Architecting the whole infrastructure and interaction between all systems.
• Designing and implementing the back-end solution for high productivity and security, data protection, and access validation.
• Designing and implementing the database.
• Designing and implementing the complex front-end React application.
• Building and maintaining the CI and CD infrastructure.

While pursuing and achieving robust and reliable functionalities on all levels, I delivered excellent code quality that followed industry standards for maintainability, readability, and development processes. I am extremely proud of having an essential role in architecting, building, and releasing the product in a tight timeframe.
