This is the first part of Sara's conversation with Shopey Mossavar-Rahmani about working as a software engineer and architect at a large Swedish furniture company’s legacy system built in 1985. They discussed the challenges of still working with this system, why it hasn’t been fully replaced, and how the efforts of moving some of the logic to other systems with better designs have been for him and his team. They also talked about ways to get other team members and, at times, the management onboarded to use cutting-edge patterns, tools, and technologies and the learnings that came along the way.
