About

Professional summary

I am a customer success and account management professional with experience owning the full lifecycle of B2B client portfolios, from onboarding and billing through renewals, escalations, retention, and expansion planning.

I have scaled and retained a portfolio of 200 customer accounts, including public institutions, while building CRM and customer service processes from the ground up. I focus on clean account data, proactive health monitoring, and early churn-risk identification.

I work effectively across sales, delivery, suppliers, and logistics teams to ensure customer commitments are met and commercial opportunities are surfaced. My approach combines operational rigor with clear, dependable stakeholder communication.

I use AI and automation tools daily to improve account planning, communication, documentation, and workflow efficiency. I am comfortable operating independently in high-pressure, multinational, and deadline-driven environments.

I am a native French speaker with fluent professional English and intermediate Spanish. My background in defense, public procurement, training, and international operations has strengthened my ownership mindset, adaptability, and ability to build trust with diverse audiences.
