MediaHub

MediaHub was A.ki's self-service retail-media platform for second-tier brands and retailers. I designed two of its core surfaces — a year-round campaign calendar and a unified campaign-analytics dashboard — turning scattered planning files and inconsistent reports into one source of truth.

Challenge

Brand teams ran retail-media campaigns using separate views, manual spreadsheets and inconsistent reports. Planning a year of promotions and judging whether a campaign worked were both hard — with no single source of truth, decisions were slow and teams were hard to keep aligned.

Outcome

Two core parts of the platform — a year-round, Gantt-style campaign calendar and a single analytics dashboard organized around the decision flow (reach → engagement → conversions).

Impact

Planning and performance moved into one reliable place, so teams could decide faster, stay aligned, and stop rebuilding the same reports — turning scattered files into one shared source of truth.

Campaign calendar

task success rate: 92% user satisfaction: 4.7/5

Brand teams now can see a full year of promotions in one place — seasonality, holidays, and live campaigns. It supports import from spreadsheets (for an easy kickstart), extensions for corporate programs and grouping by various axis.

Campaign analytics

interpretation ~35% faster time to insight: 2m 45s interpretation error rate: 6%

Campaign data lived in several inconsistent views, so clients and managers struggled to judge success quickly. I unified every metric into one dashboard, restructured the chart hierarchy around the decision flow (reach → engagement → conversions), working with analysts to ensure accuracy.
