UI representation – actual system screenshots cannot be shared

This project was developed exclusively for a national-level organization. Due to security policies and organizational ownership, public links or system screenshots cannot be shared.

This project was developed exclusively for a national-scale organization. Due to security policies and organizational ownership, sharing links or screenshots of the system is not possible. The main focus of the project was on designing a scalable front-end architecture for large systems, ensuring performance, usability, and user experience under high data volume and concurrent users.

My Role in Project

Front-End Developer (React / TypeScript) Responsible for designing and implementing the front-end layer, managing state, interacting with APIs, optimizing performance, and closely collaborating with the back-end team to define data contracts.

Challenges & Focus

Managing large volumes of data in lists and searchesImplementing advanced search and complex filteringRole-based access control (RBAC) at component and route levelsMaintaining UI performance in high-traffic pagesDeveloping a maintainable UI for a largegrowing project

Technical Decisions

Zustand instead of Redux Toolkit

Chosen for simplicity, reduced boilerplate, and avoiding complex Redux structures. Zustand enabled global state management with less overhead and higher readability.

React Query for server-side data management

Used for caching, managing loading/error states, and preventing duplicate API requests, significantly reducing backend load.

Combination of Ant Design and Tailwind CSS

Ant Design provided fast development and consistent enterprise components. Tailwind was used selectively where precise UI control and DOM optimization were needed.

Vite as the bundler

Chosen to reduce build times and improve the developer experience in a large codebase.

Solutions and Optimizations

Implemented pagination, lazy loading, and memoization to prevent unnecessary re-renders
Used debounce and caching in advanced searches to reduce Elasticsearch load
Separated temporary states from global state to avoid unnecessary coupling
Implemented RBAC at both route and component levels to prevent unauthorized rendering

Trade-offs and Engineering Considerations

To speed up development, some heavy UI customizations were avoided, focusing instead on code readability and stability
Simplified UX was chosen in high-traffic pages to maintain performance and responsiveness
Some complex client-side logic was intentionally shifted to the back-end to keep the front-end lighter and more maintainable

Outcome

This project provided hands-on experience working with large-scale enterprise systems, making real technical decisions, and managing front-end complexity. The focus was on stability, scalability, and long-term maintainability, beyond mere feature implementation.
