Juan Manuel developed and enhanced user-facing features across decentraland/ui2, decentraland/auth, and decentraland/unity-explorer, focusing on authentication, onboarding analytics, and UI/UX improvements. He implemented wallet-based login flows, onboarding checkpoints, and analytics instrumentation using React, TypeScript, and C#. In decentraland/ui2, he optimized performance with tree-shaking, responsive design, and asset loading improvements, while also refining balance visibility and navigation. His work in decentraland/auth included robust error handling, third-party integration upgrades, and security fixes for authentication flows. By delivering cross-repo features and addressing bugs, Juan Manuel demonstrated depth in full stack development, analytics integration, and collaborative engineering across complex systems.
May 2026 highlights: Implemented Web3 Wallet Login UX enhancement in decentraland/auth, redirecting users to login when MetaMask is unavailable and improving error handling to guide users through the login flow. In decentraland/ui2, added optional MANA balances in the navbar with responsive mobile adjustments via showManaBalancesInNavbar, enhancing quick balance visibility. In decentraland/unity-explorer, expanded the authentication onboarding analytics with new events (is_new_account, profile_finalized, auth_completed, new_account_onboarding_started) and ensured timely flushing of profile_finalized for real-time insights. Major impact: reduced login friction, improved balance visibility, and richer onboarding analytics enabling funnel optimization and faster decision-making. Technologies/skills demonstrated: cross-repo feature delivery, UI/UX polish, responsive design, analytics instrumentation, and collaborative development across Auth, UI2, and Unity Explorer teams.

January 2026 (2026-01) — Decentraland/auth delivered meaningful authentication, integration, and stability improvements. The team shipped enhanced email OTP login UX with auto-select logic, preserved login method on redirects, and a feature-flag controlled OTP flow, accompanied by UX validation and error handling improvements. NFT data fetch optimization reduced redundant fetches in terminal views, improving performance and test reliability. Thirdweb integration was added with dependency updates and Jest configuration improvements, expanding external integration capability while maintaining test stability. A public package naming rollback reverts to @dcl/auth-site to resolve conflicts and stabilize identity. These efforts improve user experience, reduce operational overhead, and position the repo for faster feature delivery.
