• Develop frontend interfaces and backend systems

• Build and integrate APIs and services

• Work with databases and data systems

• Collaborate with data scientists and ML engineers to integrate intelligent features

• Contribute to system design and architecture discussions

• Debug, optimise, and improve system performance

• Write clean, scalable, and maintainable code

• Participate in code reviews and engineering discussions
