●Security & Reliability: Ensure the system is secure by design (handling sensitive financial data) and highly available (robust error handling for payment flows).
●Infrastructure & Process: Establish best coding practices, set up the CI/CD processes, and ensure smooth deployment to AWS.
●Stakeholder Communication: Act as the main technical point of contact for the client, translating business requirements into technical solutions.
