Insight, Action, Expansion: Building a High-Performing Global E-Commerce Channel

Kostyantyn Cherednychenko is a 10-year eCommerce strategist currently leading all marketplace growth for Tempo Communications, a global telecom tools brand. Operating as a one-person department, he has full ownership of the eCommerce presence across the U.S., Canada, and UK — overseeing advertising, product listings, content strategy, international expansion, pricing oversight, product launches, and performance analytics.

When he joined Tempo, the marketplace channel was underdeveloped and inefficient in a highly competitive category. Without an internal team or external agencies, he rebuilt the channel from the ground up. He architected a full-funnel advertising structure using Sponsored Products, Sponsored Display, and Brand Banners, created new creatives, KPIs, and dashboards for executive reporting, and implemented growth campaigns tailored to both branded and competitor audiences.

His campaigns have driven multi-million-dollar revenue growth, expanded market share, and improved both top-line and bottom-line performance. The full-funnel portfolio has gotten 156M impressions and driven over $7M in ad-attributed sales, while maintaining profitability through strategic bidding, segmentation, and offer testing.

He also built forecasting models and performance reporting systems using Looker and Excel to align advertising with contribution margins and category trends. These tools have helped guide executive decision-making and ongoing budget optimization. He led international expansion on marketplaces in Canada and the UK, tailoring listings, targeting, and promotional strategies to each region.

In addition to execution, he manages relationships with external contractors and agencies, setting direction and holding partners accountable to performance benchmarks. With a Master’s in Data Analytics, he relies heavily on custom metrics, market intelligence, and structured experimentation to drive decisions at scale.

This nomination reflects the transformation of a stagnant eCommerce channel into a high-performing, strategically aligned growth engine—delivered entirely by a single contributor. It demonstrates what’s possible when deep analytics, operational ownership, and bold creativity converge in a lean, resource-limited environment.
