Meet the author

Robert Morel is a computer science graduate, working as a senior web developer and IT security officer for a leading cryptocurrency futures exchange. While at university, Robert started his own web development company. His first website was a static HTML site advertising a plumber. His student prices attracted business, and by the end of university, he had a team of five specializing in developing angular single-page applications and training courses.

Most of Robert’s work since then has been within fintech and blockchain. His first role after university involved migrating large financial data sets from legacy silos onto the blockchain, using Java. Working in fintech, he became an expert in developing secure and hardened web applications. Through this, he also became an experienced security researcher and ethical hacker, as well as a fintech author and blogger.

One of Robert’s favorite parts of working in web app security is having the opportunity to work with penetration testers and bug bounty hunters. Managing, assessing and resolving security reports has taught him more than ever about vulnerabilities and exploits. In his spare time, Robert enjoys developing web-scraping applications, practicing the violin and Chinese calligraphy.
