Sandra is a software turned data engineer who has spent the last nine years transforming messy, life critical data into reliable insight for national scale health systems. From the National Health Service to large footprint programmes in West, South and East Africa, she has built and rebuilt data pipelines that clinicians, policymakers, and researchers depend on every day. At heart, Sandra is a problem solver who loves watching light bulb moments in the classroom as much as seeing latency graphs drop in production. Her end-to-end vision was forged while moving from pure coding in C# to architecting full data workflows that turn raw signals into actionable intelligence. Over multiple years on global health programmes, she has engineered privacy preserving data solutions that remain robust and trustworthy long after deployment. Backed by an MSc in Data Science, an MSc in Cybersecurity, and a BSc in Computer Science, Sandra brings both theoretical rigor and hands on battle scars to the table. Drawing on a wide range of data engineering practices, she has contributed to scalable, secure, and insight driven systems used by decision makers at multiple levels. At the intersection of people and systems, she has mentored junior engineers, collaborated with clinicians to build actionable dashboards, and guided stakeholders through complex reporting transformations. Whether leading a sprint or exploring a new framework, she approaches every project with curiosity, humility, and a deep sense of responsibility and she doesn’t just teach tools; she teaches the engineering judgement behind every design choice.
