I led a team that created multiple minimum viable products (MVPs) for Novuskills, covering various scopes including mobile, desktop, and web applications. Two of these products were created in partnership with BrainCo and Dale Carnegie and incorporated neuroscience techniques to understand user attention levels and behavior.
Our team built the mobile application using Flutter and developed several libraries for internal use. Additionally, we designed and implemented a comprehensive cloud infrastructure based on Google Cloud Platform (GCP), utilizing both SQL and NoSQL databases. The web frontend was developed using Angular and was built to high-quality specifications.
