Our Expert Authors

James Harrison is the Senior Casino Analyst at CasinoUK.Expert and the driving force behind every casino review we publish. With over 12 years of experience in the online gambling industry, James brings an unmatched depth of knowledge and a forensic eye for detail to his work.

James graduated from the University of Edinburgh with a BSc in Mathematics, which gave him a strong analytical foundation that has proved invaluable in his career. His interest in probability and statistics led him naturally into the iGaming sector, where he initially worked for a major UK-based casino operator before transitioning into regulatory compliance.

For five years, James worked as a compliance consultant advising the UK Gambling Commission on operator standards, licence applications, and player protection measures. This experience gave him unparalleled insight into what separates a well-run, trustworthy casino operation from a problematic one. He has reviewed licence applications across multiple jurisdictions, assessed operator compliance with anti-money laundering regulations, and investigated player complaints at the highest level.

Since joining CasinoUK.Expert as our founding Senior Casino Analyst in 2024, James has personally reviewed over 400 casinos. His review process is rigorous and consistent: he registers at every casino using his own details, deposits his own money, tests games across desktop and mobile, evaluates bonus terms line by line, contacts customer support at different times of day, and processes real withdrawals to verify speed and reliability. His background in regulatory compliance means he can quickly identify red flags — unfair terms, questionable licensing arrangements, or patterns of player complaints — that less experienced reviewers would miss entirely.

James has published articles in several iGaming industry journals on topics including non-UK casino regulation, the evolution of offshore licensing frameworks, and best practices for bonus term transparency. He is regularly consulted by other industry professionals on matters relating to casino licensing and player protection.

Sarah Mitchell is the Content Director at CasinoUK.Expert, responsible for all guides, educational content, and responsible gambling resources on the site. With over a decade of experience in iGaming journalism and content strategy, Sarah ensures that every piece of content we publish meets the highest standards of accuracy, clarity, and reader value.

Sarah began her career in journalism before specialising in the iGaming sector, drawn by the intersection of technology, regulation, and consumer protection. She spent four years as a senior editor at Gambling Insider, one of the industry's most respected trade publications, where she covered regulatory developments across Europe, profiled major operators, and championed the importance of responsible gambling in editorial content.

During her time at Gambling Insider, Sarah was instrumental in developing the publication's responsible gambling editorial guidelines and was recognised by industry peers for her balanced, well-researched reporting. She interviewed CEOs, regulators, and problem gambling researchers, building a network of contacts across the global iGaming industry that continues to inform her work today.

At CasinoUK.Expert, Sarah oversees content strategy and editorial quality across the entire site. She writes our comprehensive player guides, develops educational resources for newcomers to online gambling, and maintains our responsible gambling section — which she considers the most important part of the website. Sarah believes that no review site should exist without genuinely helpful responsible gambling resources, and she has made this a core part of our editorial mission.

Sarah's content strategy focuses on empowering readers with the knowledge they need to make informed decisions. She translates complex topics — gambling regulation, self-exclusion programmes, bonus mathematics — into clear, accessible language that serves players rather than operators. Her editorial standards require that every piece of content is fact-checked, properly sourced, and reviewed before publication.

David Chen is the Technical Reviewer at CasinoUK.Expert, responsible for verifying the technical security, fairness, and data protection credentials of every casino we review. With an MSc in Cybersecurity and over 8 years of experience in online security, David ensures that our readers can trust the technical integrity of the casinos we recommend.

David's background in cybersecurity began during his postgraduate studies, where his dissertation focused on encryption standards in online financial transactions — research that translated directly into his professional career. After graduating, he worked for three years as a penetration tester at a leading cybersecurity firm, where he assessed the security infrastructure of online platforms across multiple sectors, including several major casino operators and payment processors.

He subsequently spent two years as a security auditor specialising in the iGaming sector, conducting technical assessments of casino platforms for regulatory bodies and operator groups. This role gave him deep expertise in the specific security challenges facing online casinos: protecting player data, ensuring game fairness, securing payment processing, and complying with data protection regulations across multiple jurisdictions.

At CasinoUK.Expert, David's technical review process is thorough and methodical. For every casino we review, he verifies SSL/TLS encryption implementation (checking certificate validity, protocol version, and cipher strength), assesses the casino's data protection and privacy policies against GDPR and international standards, verifies RNG (Random Number Generator) certifications from recognised testing laboratories such as eCOGRA, iTech Labs, and GLI, and evaluates the security of payment processing systems.

David also monitors the broader security landscape, keeping our team informed about emerging threats, data breaches affecting casino operators, and changes to encryption standards that might affect our assessments. His work is essential to our mission: if a casino's technical security does not meet our standards, it will not receive a recommendation, regardless of how strong it performs in other areas.
