Our Expert Team - Meet the Authors

At York City Walls, we believe that the credibility of our content depends entirely on the people who create it. Unlike many affiliate sites that rely on anonymous freelance writers with no industry experience, every author on our team has spent years working in the UK gambling sector. Below you will find detailed profiles of each team member, including their professional background, areas of expertise, and the articles they have contributed to this site.

Our editorial process requires that all content is written by a subject-matter expert and then fact-checked by our responsible gambling advocate, Sarah Mitchell, before publication. This dual-review process ensures accuracy, fairness, and compliance with responsible gambling principles across every page.

James Whitfield

Professional Background

James Whitfield is the founder and lead betting analyst at York City Walls. He graduated from the University of Leeds with a degree in Sports Management, which provided the foundation for a career that has spanned over 12 years in the UK gambling industry.

After graduating, James spent five years working as a compliance officer at a UKGC-licensed operator. In this role, he was responsible for ensuring the organisation's adherence to UK Gambling Commission requirements, managing responsible gambling obligations, overseeing anti-money laundering (AML) procedures, and liaising with the regulator during audits and licence reviews. This compliance background gives James an unmatched ability to assess the legitimacy, trustworthiness, and regulatory standing of gambling operators -- skills that form the backbone of our review methodology.

James left his compliance role to pursue independent journalism and review work, driven by a desire to provide UK players with honest, expert-level information about the growing non-GamStop market. He founded York City Walls in 2023 after becoming frustrated with the prevalence of low-quality, commercially motivated review sites that put affiliate commissions ahead of reader welfare.

Areas of Expertise

• Sports betting odds and markets: James is an expert in evaluating odds quality, market depth, and value across football, horse racing, tennis, cricket, and other sports. He assesses bookmaker margins, compares odds against industry benchmarks, and identifies operators that consistently offer competitive pricing.
• Operator evaluation and licensing analysis: Drawing on his compliance background, James scrutinises the licensing credentials of every operator, verifying licence validity with issuing authorities and assessing the quality of the regulatory framework under which each site operates.
• Payout reliability testing: James personally tests withdrawal processes at every site, recording processing times, verification requirements, and any issues encountered. He has processed over 500 test withdrawals across dozens of operators.
• Regulatory and legal analysis: James provides expert commentary on the regulatory landscape for non-GamStop operators, including changes to UK gambling law, offshore licensing developments, and the implications for UK players.

David Thompson

Professional Background

David Thompson brings a fintech background to the York City Walls team and is our specialist on all matters relating to payment methods, banking solutions, and cryptocurrency transactions in the online gambling space. With over 6 years of experience covering payment solutions for online gambling, David has an unrivalled understanding of how money moves in and out of non-GamStop betting sites.

David's career began in the fintech sector, where he worked on payment processing systems for e-commerce platforms. His transition into the gambling payments space came naturally, as he recognised the unique challenges that online gambling presents for both operators and players -- particularly in the non-GamStop market, where payment routing, currency conversion, and regulatory compliance create complexities that do not exist in the UKGC-licensed space.

David has personally tested deposit and withdrawal methods at over 100 gambling sites, documenting processing times, fees, minimum and maximum limits, and any issues encountered. He is particularly knowledgeable about cryptocurrency payments, having used Bitcoin, Ethereum, Litecoin, Tether, and numerous other cryptocurrencies for gambling transactions across dozens of platforms. He also has deep expertise in e-wallet solutions including Skrill, Neteller, and ecoPayz, as well as traditional card and bank transfer payments.

Areas of Expertise

• Cryptocurrency gambling payments: David is our authority on using Bitcoin, Ethereum, and other cryptocurrencies at non-GamStop sites. He evaluates transaction speeds, network fees, wallet compatibility, and the overall user experience of crypto deposits and withdrawals.
• E-wallet and banking solutions: David tests and evaluates traditional payment methods including Skrill, Neteller, ecoPayz, Visa, Mastercard, and bank transfers, with a focus on processing times, fees, and reliability.
• Payout speed verification: David independently verifies the withdrawal processing times claimed by operators, providing readers with real-world data rather than marketing promises.
• Currency conversion and fees: David analyses the hidden costs of using non-GamStop sites, including currency conversion charges, payment processing fees, and any other financial considerations that players should be aware of.
