Tiago Leichsenring

Took over all online customer acquisition for a Berlin-based care placement company. Built the full analytics stack (GA4 + GTM + BigQuery + SQL + Looker Studio), optimised all paid media channels (Google Ads, Meta Ads, Taboola, Bing), developed a marketing strategy for two brands (Linara + FairCare), and ran international Google Ads campaigns across four Eastern European markets. In parallel: independently conceived, developed and launched an AI chatbot (Python/Flask) for automatic lead qualification.

Problem: 70% of all incoming leads were unqualified, costing the sales team measurable time every day. Independently conceived and developed: an AI-powered chatbot for WhatsApp, Telegram, Messenger and Webchat that qualifies leads before any human contact. No agency. No off-the-shelf tool. Concept, architecture, development, launch — all internal.
