I've driven end-to-end growth for digital products across B2B and B2C markets, turning customer and competitor research into positioning, acquisition funnels, lifecycle campaigns, and measurable revenue outcomes.

At Pifagor School, I led growth and launched a new IELTS preparation product, owning positioning, pricing, funnel architecture, and experimentation across paid social, retargeting, influencers, SMM, community, and email. I coordinated up to 10 specialists and helped reach 600+ students, or 71% capacity.

At Grizzly Digital Company, I launched an AI Research/GEO service for a B2B MarTech business and translated a technical offer into landing pages, lead magnets, pitch decks, content, and email sequences. The new product generated 15% of total revenue while organic engagement grew 40%.

Previously, at LLC Lifestyle, I built an education subscription product from zero and improved CRM segmentation, personalized offers, sales processes, and retention initiatives. That product achieved 4x LTV growth with 90% retention.
