Alistair Curtis developed and maintained the digital-prison-reporting repository, which supports reporting workflows within the justice sector. He designed backend services using Python and Django to handle secure data processing and user authentication, ensuring compliance with government standards. Alistair integrated PostgreSQL for reliable data storage and retrieval, focusing on transactional integrity and scalability. He implemented RESTful APIs to facilitate communication between internal systems, enabling seamless data exchange and automation of reporting tasks. His work addressed the need for robust, maintainable infrastructure, and he demonstrated depth in both application architecture and security practices, resulting in a stable platform for justice sector reporting operations.
