What I'm looking for

I seek a customer-centric role combining technical support and billing/collections within a process-driven, collaborative company offering growth and impact.

I am a customer-focused professional with extensive experience in technical support, digital services, and customer care across international environments.

I have a strong background in troubleshooting hardware, software, connectivity and platform issues, providing support via phone and ticketing tools, and coordinating with field technicians and frontline teams.

I also bring hands-on experience in billing, invoice verification, payment reconciliation and credit collection, having managed billing processes and timely follow-ups to resolve discrepancies.

I communicate effectively in English and French, work well in process-driven environments, and consistently prioritize customer satisfaction while meeting operational and financial targets.
