Every customer who doesn't come back is revenue you already paid to acquire—lost. I specialize in stopping that leak: reactivating accounts, turning support conversations into upsells, and keeping your sales pipeline moving through outbound calling and appointment setting. Here's what that's looked like in practice: I've run outbound retention campaigns that recovered refill and reactivation conversions on accounts written off as lost. I've turned routine customer interactions into upsell revenue by listening for the right moment instead of following a script. I've cold-called and qualified leads for a fitness brand, booking consultations that filled a sales director's calendar. And right now, I support B2B order processing and invoicing for a distributor—catching upsell opportunities inside everyday transactions and keeping billing airtight. What ties it together: I don't treat retention, sales, and support as separate skills. A refund request is a chance to save the relationship. A support ticket is a chance to upsell. A cold call is a chance to build trust before you've even made a sale. That mindset is what turns a support rep into a revenue driver. If you're losing customers to churn, missing follow-ups, or leaving upsell opportunities on the table because your team is too busy putting out fires—that's exactly the gap I close. ✔ Customer Retention & Reactivation Campaigns ✔ Cold Calling, Lead Generation & Appointment Setting ✔ Upselling & Cross-Selling During Support Interactions ✔ Order Processing, Invoicing & Account Management ✔ Refund, Return & Order Resolution ✔ CRM Management & Accurate Documentation ✔ Complaint Resolution & De-escalation ✔ Tools: HubSpot, Shopify, Freshcaller, Calendly & QuickBooks Tell me what's costing you customers or sales—let's fix it.

I've spent 3,789 hours and 24+ months as a Tier 2 Customer Support Specialist for a fintech platform (Atlas), maintaining a 5.0 rating while handling escalations, KYC verification, payment disputes, and account issues under SLA pressure. That client relationship alone earned $26,000+, a track record of consistency clients can check for themselves. Before that, I supported customers and drivers on a global mobility platform (inDrive) and a major food delivery marketplace (Uber Eats), handling KYC checks, fare and payment disputes, refunds, and account troubleshooting across phone, email, and chat. Always maintaining accurate CRM documentation. I'm comfortable working independently across Zendesk, Salesforce, Intercom, and Freshdesk, and I pick up new tools and internal processes quickly. Clients don't need to hand-hold me through onboarding. I document as I go and keep tickets moving without dropping SLA. Core strengths: - Tier 2 escalations & complex issue resolution - KYC verification, payment disputes, account investigations - Zendesk, Salesforce, Intercom, Freshdesk - Clear written and verbal communication under pressure - Fast onboarding, minimal supervision needed If you need someone who can walk into your support queue and start resolving real tickets, not just answer FAQs, let's talk.
