Web Applications

Browser-based software utilizing the client-server model: it delivers interactive user experiences via standard protocols (HTTP/S) and core technologies (HTML, CSS, JavaScript).

Web Applications are dynamic, cross-platform software systems executed directly within a standard web browser, eliminating OS-specific installation friction. The architecture is fundamentally client-server: the client-side (frontend) uses frameworks like React or Vue.js for rich UI, communicating with a server-side (backend) via REST or GraphQL APIs to manage data persistence and business logic. This model supports mission-critical services like Software as a Service (SaaS) platforms (e.g., Salesforce, Microsoft 365) and high-volume e-commerce (e.g., Amazon), enabling rapid, universal access across desktops, tablets, and mobile devices.
