Detlef W.

Operations Project Manager | AI Agents, CRM & Support Automation

66% faster first response. 70% fewer tickets. 4.5% conversion on comments an AI agent handled instead of a person. I rebuild support operations, and I bring the numbers with me. The help desk, the automation, the agents, and the reporting that proves any of it moved. 🤖 AI AGENTS THAT ACTUALLY CLOSE. Everyone has a chatbot now. Almost none of them sell anything. Most answer one question, lose the thread, and hand over a cold lead two days later. The agents I build carry layered context: who the person is, what they asked three messages ago, which offer they were looking at, what was already promised to them. They follow up on their own. They hold a thread across several days without resetting. They take someone from a comment under an ad, into DM, to a decision, without a human in the middle. At that scale, the maths changes. Agents I have written and tested handle comment volume no team reads by hand: over 500,000 comments across 11 brands, more than 2,000 a day on the busiest account, 4.5% conversion on the comments they handled, and zero manual replies from the client's own team. Plenty of people can switch a chatbot on. Far fewer can build one that closes. 🏗️ BUILDING SUPPORT OPERATIONS FROM ZERO At FoodAmigos I built the entire customer support function in 8 months and led the 5-person team that ran it. First response time 4:52 to 1:38, a 66% cut Trustpilot 3.7 to 4.8 in six months 90% positive feedback after every resolution Phone support launched on Aircall, call quality 3.7 to 4.6 Around 70% less manual work overall, through automation and documentation 🌍 INTERNATIONAL ROLLOUTS On Amazon's DSP program, I led the expansion of a workforce platform into Austria, Luxembourg and Switzerland. 3 countries, 12 stakeholders across legal, product, and operations, delivered in 10 months 100% compliance on payroll, labour law, and Amazon policy 400 B2B accounts managed, 200+ onboardings run Weekly tickets from about 100 to about 30, a 70% cut, via a help center and a video certification path I built and narrated 💳 CHARGEBACKS AND PAYMENT DISPUTES At Voggt, a live auction marketplace, most volume ran through PayPal, and high-value items attract claims constantly. 500+ disputes and claims handled 65%+ resolved in our favour €30,000+ in disputed revenue recovered 20% cut in preventable dispute losses Most cases answered within 24-48 hours. Winning disputes matters less than preventing them. I map the reason codes first, then fix the two upstream causes that drive most of them. ⚙️ WHAT I ACTUALLY DO FOR YOU Design and implement the stack: Intercom, Zendesk, HubSpot, Aircall, Shopify Build AI agents and automations that remove the repetitive work Write the SOPs and documentation so the system survives people leaving Define the five KPIs that change a decision, and build the reporting Hire, train, and manage remote support teams Run market expansions where regulation and product differ per country Languages: German, Portuguese, and English at C2, Spanish at C1, French at B2.
