I was solely responsible for the architecture and design of the website and mobile app for a predict-to-earn market in polygon network. I led the blockchain and Front-End development teams during the design and planning phases, guiding them through the solution and implementation. After collaborating with the client's security team, I created an optimal cloud infrastructure solution that met their functional and security requirements. I analysed the functionality of the microsite to gather the data requirements and used this to devise the most efficient database schema for PostgreSQL. I also created detailed architecture diagrams and a comprehensive technical design breakdown of the Google Cloud architecture, including justifications and decisions made for each service, along with implementation and configuration steps.
