@janakostrzewa
Customer support professional with strong CRM and teaching background.
What I'm looking for
I am a customer support professional with hands-on experience resolving customer issues, troubleshooting, and documenting cases in CRM systems. I combine strong communication skills with a commitment to delivering high-quality support.
My background includes roles in customer support at CPM International and HR generalist responsibilities where I managed onboarding, employee records, and administrative HR processes. I have practical experience with CRM platforms such as Zendesk, Salesforce, Freshdesk and with ticket handling and case management.
Prior to my customer-facing roles, I worked as a homeroom teacher where I led language development coordination, provided continuous feedback, coaching, and performance evaluation. This teaching experience strengthened my multitasking abilities and my capacity to manage fast-paced environments.
I hold a Master of Education (M.Ed.) and a Bachelor of Arts (B.A.) in German and related fields from Leibniz University Hanover, and I am seeking to apply my customer-focused mindset and problem-solving skills to a dynamic support team.
