About the projectThe goal of the project is to design and build a modern, scalable analytics platform for the banking sector. It will support the creation, management, publishing, and distribution of analytical content prepared by the Investment Analysis team of the brokerage office.Initially, the system will be used by institutional clients, and later also by individual clients.The platform will help analysts better use their expertise, reduce manual work, and organize a large amount of analytical content, including market comments, company analyses, valuations, financial results comments, and sector reports. It will also provide clear data on how users consume the reports.The solution must meet high standards of security and availability. It will be designed with a mobile-first approach, fully responsive (RWD), and compliant with WCAG 2.0 standards.Project duration: 10–11 months.We are also looking for developers for other projects:Mobile Banking Platform (SaaS)This project focuses on developing and customizing a mobile banking platform delivered in a Software-as-a-Service (SaaS) model.
