The application included an analytics dashboard for the team leaders to oversee project timesheets synced with a real-time data source and perform quantitative analysis of future project bids.

As the front-end developer, I liaised with the back-end developer in the database and REST API design. We developed a project management tool for monitoring the status and budget of projects, which saved the company around $40,000.

Components Library in Storybook

A component library in Storybook for Vinhood. Vinhood creates a taste ecosystem for food, beverages, and other products based on gastronomic, sensory, and neuroscientific research and designs quizzes for consumers to explore their taste profiles.

This allowed the company to use the component-driven design (CDD) strategy for its user interface development lifecycle.
