DESIGN AND DEVELOPMENT OF A SERVERLESS MICROSERVICES WEB APPLICATION

We set out to build a secure, scalable alternative to the fragmented manual systems many organizations still rely on for digital information management. The resulting Serverless Microservices Web Application brings user management, document storage, JWT-authenticated access control, and administrative monitoring together in a single, maintainable system backed by React.js, FastAPI, and SQLite/PostgreSQL. Testing confirmed that each module — authentication, document handling, user management, activity monitoring, and API services — operates reliably under multi-user conditions. The microservices structure gives the system flexibility: services can be modified or replaced independently, reducing the cost and risk of future changes. Real-time dashboard access and structured activity logs directly support the operational transparency that administrators need. For institutions and enterprises seeking a dependable foundation for centralized data governance, this platform offers a practical, deployable solution. Future work will focus on cloud deployment across AWS, Azure, and GCP; integration of machine learning for predictive analytics; multi-factor authentication for additional credential security; and a dedicated mobile client to extend access beyond the browser.
