What I'm looking for

I am seeking a role where I can lead onboarding and client success, drive adoption and revenue, collaborate cross-functionally, and continue developing enterprise-level implementations in a client-focused culture.

I am an experienced Client Relationship and Onboarding Manager with a track record of leading complex implementations, improving onboarding processes, and driving revenue growth across SaaS and e-commerce platforms. I have led onboarding for enterprise and mid-market clients, collaborated with product and sales teams, and contributed to product roadmaps while delivering measurable commercial impact.

I bring strong stakeholder management, training, and project delivery skills honed at Legl, LoyaltyLion and Shopify-focused agencies, and have generated substantial new business and upsell revenue in previous roles. I am personable, adaptable, and motivated to build long-term client relationships and successful implementations that increase adoption and decrease churn.
