We participated in the development of this financial platform for loans, deposits, and credit cards using Vanilla JavaScript with server-side rendering for sub-second page loads and strong SEO, and a .NET Core microservices backend with RabbitMQ, PostgreSQL, MongoDB, Redis, and Ocelot API Gateway, all containerized with Docker on CentOS and automated via Jenkins pipelines, achieving a 75% reduction in load times and near-perfect Google PageSpeed scores to improve discoverability and user experience.
