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 are handled through a custom Stripe integration built from scratch (no WooCommerce), and every feature — from the assessment engine and coach dashboards to the partner logo strip — is custom code.
