Project scope

Development of an e-learning platform from scratch, including an authentication system, course catalog, user profile, and a marketing site with pricing and a contact form. The implementation covered database design, server-side logic, and user interface development.

Technical challenges

Designing a relational data model for nested structures (courses → sections → lessons) and transforming flat SQL query results into structured, hierarchical objects. Building a full authentication system from scratch, including registration, login, protected routes, and secure session handling.

Architecture and solutions

Separation of logic into server-side (responsible for data and security) and client-side (responsible for interactions and forms). Implementation of optimistic UI updates with debounced requests for the like system, ensuring a smooth user experience without waiting for server responses. Use of shared validation schemas across client and server to ensure consistent data validation.

Key decisions

• Adoption of server-side rendering to improve performance and simplify data handling.
• Implementation of stateless user session management.
• Use of a database optimized for cloud environments.
• Ensuring consistent data validation across the entire system.

Final outcome

Delivery of a complete, production-ready full-stack application: 10 database tables, 8 API endpoints, and over 35 React components. Includes a full authentication system and was developed end-to-end independently, with pixel-perfect implementation of the Figma design.
