Co-author: Sam Sgro is an experienced technologist, architect, and engineering leader with decades of hands on experience. Sam is a strong believer in how combining logic and reason with the right principles can bring about a better world, and his career has been about applying architecture and engineering in the best possible way, solving complex business and technology problems to help people.

Sam’s early background was a mix of both molecular biology and computer science, working in projects spanning open source cryptography and high performance computing. Slowly transitioning from having fun with Solaris and Linux to Java software engineering, Sam joined an early-stage bioinformatics and data analytics startup with a successful exit to Thomson Reuters. Since then, Sam has served as an engineering and architecture leader for teams across the US, Canada, UK, Spain, India, Ukraine, and Brazil, delivering multimillion-dollar growth and transformation initiatives across many industries, including pharmaceutical research and academic literature analysis.

Sam’s driving passions are solving problems, delivering software and helping people find their place in the world and hone their true capabilities. Sam loves delivering interesting and innovative tech solutions, such as in the early days using the Netflix stack, Cassandra and ElasticSearch, finding ways to creatively migrate technology to AWS, or building voice-based mobile applications to connect the world’s knowledge. Sam loves running, hiking and spending time with his family and kids, fitting in video games when time permits.

Sam currently serves as the architecture and consumer engineering lead of a FinTech company based in the Bay Area.
