KEY RESULTS AND PROFESSIONAL CASE STUDIES

• 2009–present · end-to-end digital projects: Collaborated with Yevhen Hukov on websites and marketing products, from initial ideas, prototypes, UX/UI, and content concepts through user behavior tracking, conversion improvements, and client support. Their shared portfolio includes 500+ websites and landing pages. This figure reflects joint work, not websites developed by Olena alone.
• Hayali · Google Ads cost per conversion: The team lowered cost per conversion from $3.00 to $0.50 (approximately 83.3% lower). Olena's primary responsibilities were analytics, UX design, user journey research, and sales manager training. This metric is not the cost of acquiring one paying customer.
• Hayali · 10–12% website conversion rate: The rate was measured against all website traffic, not just paid-ad clicks. Project reports recorded 143–147 leads per day before the New Year holidays and 50–86 per day afterward. These are team-level historical results. The original reports are no longer available.
• IamGhostProducer · audit of ineffective advertising spend: Identified an error in how the advertising service processed URLs. Properly created landing page URLs became invalid during click-throughs and led to HTTP 404 errors. The advertising service confirmed in writing that the problem was on its side. The issue lasted approximately three months and prevented conversions while the campaign's monthly advertising budget ranged from $7,500 to $12,000. This range represents the campaign budget, not a calculated or substantiated amount of losses.
• Halal Holiday Check · communication and sales processes: Audited acquisition and retention. Structured the path from ads and social media to the call center. Developed algorithms and scripts for agents and contributed to visual channel branding and chatbot scenarios.
• Head of Search Quality (NDA): Led search quality, relevance, and results evaluation. Developed evaluation methodology and cross-disciplinary collaboration. The employer, internal data, and confidential outcomes are not disclosed.
• WebPocket OÜ · two part-time roles: Works on digital platform architecture and performance marketing analytics within the same product environment. Handles architectural requirements, user journeys, performance measurement, and collaboration with product and engineering teams.
• International markets and clients: Has worked with advertising, analytics, digital products, and travel offerings internationally. Destinations covered by travel planning are listed separately from advertising markets.
