What I'm looking for

I'm looking to solve complex operational and growth challenges in fintech, payments, or financial services, where I can improve systems end-to-end, use AI to scale workflows, and work closely with clients and cross-functional teams.

I'm driving adoption of fintech platforms for payments, trade booking, and settlement at Leonteq Securities, improving system usage and internal process efficiency while managing client relationships end-to-end.

At Zanders, I led an end-to-end FX process and strategy review for a private equity client, mapping teams, stakeholders, and workflows to deliver actionable technology and process recommendations. Previously at BlokBe Crypto Payments, I owned merchant onboarding from partner meetings through implementation and account support, contributing to a partner base of around 40 merchants.

I've also closed deals and onboarded 20+ clients in asset and wealth management, rebuilt a firm website, and integrated generative AI into marketing workflows to help scale output. My experience spans market research, investment ideas, treasury operations, risk exposure monitoring, and financial services regulation.

I'm energized by spotting inefficiencies, building data-backed fixes, and using AI to work faster and smarter. I bring an entrepreneurial, client-focused approach to complex operational challenges.
