During 2020, I architected and built Ziina.com mobile wallet for the UAE market. The stack? NodeJS, Typescript, GraphQL, PostgreSQL, Jest and React Native. The company was able to make a successful launch within 4 months of intensive development.

More developers joined the source-code effortlessly due to a well-architected and understandable codebase.

Most importantly, the company was able to focus on new features and adoption because bugs were minimal.

After the adoption period, we moved to a 2nd phase with a cost-effective micro-service architecture featuring gRPC communication, SQL queries and GraphQL endpoints, allowing the company to adapt quickly and achieve its stakeholders vision.
