  • Translate user and business requirements into robust technical solutions.
  • Design, build, and maintain RESTful APIs, ensuring performance, reliability, and security.
  • Collaborate with UX designers to implement responsive, accessible, and user‑centred frontend features.
  • Lead development activities, support code reviews, and uphold engineering best practices.
  • Work with architects to align solutions with enterprise patterns, standards, and cloud strategies.
  • Implement secure development practices and ensure solutions meet compliance and data‑protection requirements.
  • Participate in technical planning, estimation, and risk assessment across the delivery lifecycle.
  • Support continuous integration, automated testing, and deployment pipelines.
  • Troubleshoot issues across the full stack and contribute to improving system observability and performance.
  • Produce clear technical documentation, including architectural diagrams, data flows, and API specifications.
