Build and maintain RESTful and GraphQL APIs to support frontend systems and external service integrations.

Integrate with PostgreSQL databases using ORM tools such as Sequelize and Knex.js.

Design and implement performant and reliable systems by applying appropriate caching strategies and integrating distributed components such as Redis, CDNs, and message queues.

Handle file uploads and processing using tools like Multer, ExcelJS, and CSV Parse.

Ensure secure authentication using frameworks such as Azure MSAL Node, JWT, and express-session.

Optimise backend services for scalability, performance, and security.

Develop and maintain scalable, high-quality frontend components using React, Material-UI, Emotion, and related libraries.

Build responsive, accessible, and performant user interfaces, ensuring cross-browser compatibility and adherence to accessibility standards (WCAG).

Collaborate with backend engineers to integrate RESTful/GraphQL APIs built with Node.js and Express.js.

Work with PostgreSQL databases via Sequelize or Knex.js, and implement client-side caching (e.g., IndexedDB, Redis).
