Led conception and development of GEM, an enterprise ERP (Next.js + Supabase/Postgres) that replaced Excel workflows and accelerated operations by up to 80%. • Real-time Kanban (multi-view, drag-and-drop, subtasks, automation), corporate chat (channels, threads, voice messages, DMs) and GPT-powered AI assistant — all via Supabase Realtime/WebSockets. • Dashboards with productivity metrics, trend analysis and financial reporting. Append-only audit log with RBAC. • Multi-layer caching (SSR/RSC + Zustand + TanStack Query), 5,000+ lines of Prisma schema. Docker + Nginx on VPS. • Kotlin Multiplatform tooling (Compose + Ktor) for automated CAD export workflows. Desktop app with Tauri.

Independent consultant delivering production mobile apps end-to-end, from native modules (Swift/Kotlin) to full React Native products with real-time architectures and store deployment. • Built a subscription VOD streaming platform (React Native, New Architecture) with HLS adaptive playback, offline downloads, native PiP/AirPlay, Watch Party via LiveKit/WebRTC and Stripe/Mercado Pago billing. • Developed a hospital management mobile app with biometric auth, real-time dashboards, optimized list rendering and offline data entry. • Performance engineering: virtualized lists, memoization, image caching strategies, buffer tuning and debounced state persistence. • Release pipelines with EAS Build and Fastlane. Deep linking via Universal Links (iOS) and App Links (Android). • Backend integration: Supabase (Auth/DB/Realtime/Storage), PostgreSQL, REST APIs, real-time sync.

Developed a React Native mobile app for a hospital management system — biometric authentication, real-time operational dashboards, multi-step form workflows with validation and offline-capable data entry for patient records, scheduling and inventory. • Performance focus: virtualized lists for large patient datasets, memoized components, optimized re-renders and efficient REST API consumption with loading states, error boundaries and caching strategies. • Responsive UI following design system patterns and mobile best practices — platform-adaptive components and consistent UX across iOS and Android.

Developed and maintained React Native mobile apps for ISP management — customer data, billing and support flows. Migrated legacy modules to modern React Native with TypeScript. • REST API integration, offline data handling and responsive UI for field technicians. • CI/CD pipelines with GitLab (Git Flow) and agile workflows (Scrum/Kanban).
