Your host is Tobias Macey and today I'm interviewing Effie Baram about data engineering in the finance sector Interview Introduction How did you get involved in the area of data management? Can you start by outlining the role of data in the context of Two Sigma? What are some of the key characteristics of the types of data sources that you work with? Your role is leading "foundational data engineering" at Two Sigma. Can you unpack that title and how it shapes the ways that you think about what you build?How does the concept of "foundational data" influence the ways that the business thinks about the organizational patterns around data? Given the regulatory environment around finance, how does that impact the ways that you think about the "what" and "how" of the data that you deliver to data consumers? Being the foundational team for data use at Two Sigma, how have you approached the design and architecture of your technical systems?How do you think about the boundaries between your responsibilities and the rest of the organization? What are the design patterns that you have found most helpful in empowering data consumers to build on top of your work? What are some of the elements of sociotechnical friction that have been most challenging to address? What are the most interesting, innovative, or unexpected ways that you have seen the ideas around "foundational data" applied in your organization? What are the most interesting, unexpected, or challenging lessons that you have learned while working with financial data? When is a foundational data team the wrong approach? What do you have planned for the future of your platform design?
