Daniel Bertolozi is a software developer at SAP with more than 5 years of experience focused on SAP Fiori development. He has worked on several projects implementing SAPUI5 applications (in JavaScript and TypeScript) applying best practices for code quality, and he is actively engaged in disseminating agile software engineering practices around SAP. Daniel's approach to software development follows Robert C. Martin's phrase: "The only way to go fast, is to go well". If quality decreases, speed eventually will too, and that's what we want to avoid.
