Customer Success Manager at Supplier.io, managing 100 SaaS accounts and supporting renewals and expansion.

United States
Message

At Supplier.io, I own customer lifecycle engagement across approximately 100 SaaS accounts, including adoption, renewals, risk identification, and executive business reviews. I use customer health indicators, platform usage, and business goals to prioritize support.

I created and shared an upsell-trigger playbook to make expansion discovery more repeatable across the team. I also coordinated sales and service delivery for an approximately $20K ARR managed-services expansion, from needs assessment through scoping and implementation.

As an Implementation Project Manager at Supplier.io and Flexe, I managed enterprise SaaS implementations and aligned customers and internal teams on requirements, milestones, risks, and go-live readiness. At Flexe, I designed standardized implementation tools and workflows to improve consistency, onboarding, and customer experience.

Earlier, I planned supply chain operations at Green Thumb Industries and supported the design and launch of Microsoft Dynamics 365. At Fastenal, I managed implementation lifecycles for enterprise software, hardware, and systems across customer environments.
