Previously, at Lloyds Banking Group, Melissa held Director-level positions in Financial Institutions Sales, Corporate Solutions, and remediation, Relationship Director for global asset managers, and was Sales Lead for the IRHP review, overseeing cross-functional teams of around 50 professionals. Earlier roles at Deutsche Bank, HSBC and Citibank in operations, FX, money markets and derivatives gave Melissa a broad grounding across front- and back-office functions in global markets.

Melissa’s areas of expertise from her financial services career include the structuring, pricing, and execution of interest rate and FX hedging solutions, including swaps, caps, collars, cross-currency swaps on large transactions for corporates, financial institutions, and private equity sponsors. Melissa has extensive experience in capital markets and complex financing, such as structured funding, whole business securitizations, portfolio restructurings, and receivables and shared-equity structures for global corporate and FI clients.

Melissa has also led high-profile conduct, remediation, and disputes work, including an FCA review into alleged mis-selling of interest rate hedging products, loan documentation reviews informed by emerging case law, and sensitive trader-activity investigations alongside legal and regulatory stakeholders. This combination of banking, derivatives and expert witness experience provides a strong interface between legal teams and practitioners with frontline financial markets expertise. This experience supports law firms and their clients in navigating complex, high-value financial disputes with confidence.
