@veljkomladenovic
I lead data-driven customer support operations, quality, and agent performance.
What I'm looking for
At N1 Partners Group, I support customer service operations as a Team Leader & Quality expert, using KPI analysis, audits, coaching, and workflow standards to improve support quality. I increased new-agent performance from approximately 62–63% to consistently 78–80%+ and introduced response-time standards of two minutes or less.
I’ve worked across live chat, phone, email, and social media support at N1 Partners Group and Foundever, resolving payment, technical, account, order, refund, delivery, and customer-dispute issues. On The Body Shop campaign, I handled Facebook and X messages, customer comments, and retail help desk issues while helping prevent escalations.
I focus on scalable processes, clear communication, accurate compliance, and ownership of customer cases. I collaborate with CRM, Payments, and Tech teams to resolve complex issues, improve queue management, and strengthen customer experience.
