In one paragraph
I am a turnaround fractional CMO working remotely with B2B clients. I step into a project when marketing is broken: the contractor is burning budget, sales have dropped, the team fell apart, or there is no marketing function at all. I audit the incumbent vendors, rebuild the team and own the numbers in front of the founder. SEO and paid search I verify myself, hands-on (on smaller projects I also run them myself) - down to page speed, logs and indexing; social and SMM are delivered by vendors under my management. Before marketing - 10 years running operations: brigadier in Minsk and Petersburg, then ops manager, then head of operations with shifts up to 100 people. Long-term B2B contracts of my client companies with Rosatom, Tikkurila, MC-Bauchemie, Yasnye Zori poultry farm and Sestroretsk bread plant. Industries with confirmed cases: cleaning (×3 revenue in 3 years 9 months), offline retail (CPL 31.9 RUB, 1st place among 21 stores in a 5km radius), countryside construction comfort-class (×1.5 revenue in 12 months), mass hiring (1500+ vacancies closed). Self-employed (Russian NPD). VAT: 780638102613.
