At KTO Group, I built loyalty, gamification, and player-engagement features in React and TypeScript, including the Trunfo free-to-play game. I also integrated Smartico into the player-facing product and shipped features behind feature flags across staging and production.
I built and launched identity-js, a live analytics SaaS, as a solo full-stack project. It includes cookie-free visitor analytics, a public REST API, a real-time dashboard, and Stripe subscription billing.
