Real-time voice AI applications with OpenAI Realtime API, Vapi agents, and best-in-class STT/TTS providers. \n \n Covers three primary architectures: native OpenAI Realtime API for integrated voice-to-voice, Vapi for hosted phone and web agents, and modular pipelines combining Deepgram STT with ElevenLabs TTS \n Emphasizes streaming at every layer (interim transcription, token-level LLM output, chunked audio synthesis) to minimize latency and preserve conversation flow \n Includes barge-in detec

Best practices and architectural patterns for Vue 3 and Nuxt 3 projects. \n \n Emphasizes core principles: predictable state with single source of truth, explicit data flow (props down, events up), and small focused components \n Requires Composition API with <script setup lang=\"ts\"> as the default, and mandates following detailed guides for reactivity, SFC structure, and component organization \n Provides a checklist-driven approach covering component splitting, composable extraction, an

Write failing tests first, then minimal code to pass, then refactor while keeping tests green. \n \n Follows the red-green-refactor cycle: write one failing test, verify it fails correctly, implement minimal code to pass, verify all tests pass, then refactor safely \n Requires watching each test fail before writing implementation code; tests that pass immediately prove nothing about correctness \n Applies to all new features, bug fixes, refactoring, and behavior changes; code written before test

Native Android development with Kotlin, MVVM architecture, Jetpack Compose, and modern libraries. \n \n Covers MVVM pattern with Jetpack ViewModels, StateFlow for reactive state management, and Hilt for dependency injection \n Includes Jetpack Compose for declarative UI, Retrofit for API integration, and Room for local SQLite persistence \n Provides reference implementations for models, API services, ViewModels, and Compose UI components \n Emphasizes coroutines for async operations, proper life

Use @wire decorator for reactive data binding with Lightning Data Service or Apex methods. @wire fits LWC's reactive architecture and enables Salesforce performance optimizations.

Native iOS app development with Swift, SwiftUI, and modern async patterns. \n \n Covers MVVM architecture, SwiftUI declarative UI, URLSession networking, and Combine reactive programming \n Includes async/await patterns, Core Data persistence, and Keychain for secure storage \n Best practices emphasize dependency injection, proper error handling, @StateObject for ViewModels, and testing across iOS versions \n Reference guides provided for network services, MVVM setup, and SwiftUI view implementa

Structured PRD creation from discovery notes to engineering-ready requirements document. \n \n Orchestrates 8 phases across 2–4 days: problem framing, persona definition, strategic context, solution overview, success metrics, user stories, and scope/dependencies documentation \n Includes problem statement with evidence, target personas, business goals, and competitive context to align stakeholders before engineering begins \n Breaks solutions into epic hypotheses and user stories with acceptance

Web frontend development with CloudBase integration, static hosting deployment, and SDK-based authentication. \n \n Covers project structure conventions (src/dist/cloudfunctions directories), modern build systems (Vite, Webpack), and hash routing for static hosting compatibility \n Provides CloudBase Web SDK integration patterns for database, cloud functions, and authentication, with strict rules against implementing login logic in cloud functions \n Includes deployment guidance for CloudBase st
