Real-money iGaming platform. Joined mid-rebuild — a UI redesign running in parallel with an architecture rework, on top of heavy accumulated legacy.
Architecture & refactoring
- Key refactors — network layer centralization, splitting 2–3k-line god components and stores (with legacy parity), Vue 3 typing standardization, and security hardening across user flows.
Product & features
- As one of two frontend engineers, owned 18+ end-to-end product features across 50+ epics — retention events, onboarding, new banner system, referral program, reward claim.
Process & team
- Every feature shipped through a full production cycle — responsive on desktop/tablet/mobile, unit-tested, localized via admin panel, CDN-delivered with WebP + compression, event tracking via PostHog.
