The Challenge
Athletes and coaches lacked science-based tools to understand how personality influences sports performance. Existing personality assessments were either too generic or too academic to be actionable in a sporting context.
The Approach
I designed and built the entire platform as a custom WordPress application on an Astra child theme – 183K lines of hand-written PHP, JavaScript, jQuery and CSS. The core is a proprietary 4-pillar psychometric framework: Drive (Intrinsic vs Extrinsic), Competitive Style (Strategic vs Opportunistic), Cognitive Approach (Technical vs Reactive) and Social Style (Collaborative vs Autonomous) – producing 16 distinct sport personality archetypes. Payments run through a custom Stripe integration built from scratch (no WooCommerce), and premium reports are generated by AI through background job queues.
