1. Recomendaciones para Product Manager
1.1 Roadmap Propuesto (4 Fases)
FASE 1: Security & Blockers (Q1 2026) - 201h
Objetivo: Eliminar P0-P1 que bloquean go-live.
| Item | Epic | Esfuerzo | Impacto Business | ROI |
|---|---|---|---|---|
| Auto-refresh tokens | OQI-001 | 60h | 🔴 CRÍTICO (seguridad) | INMEDIATO |
| PCI-DSS compliance | OQI-005 | 80h | 🔴 LEGAL (pagos) | INMEDIATO |
| Video upload | OQI-002 | 60h | 🟠 ALTO (educación bloqueada) | ALTO |
Justificación:
- Sin auto-refresh: usuarios se desloguean cada 1h → abandono
- Sin PCI-DSS: NO podemos procesar pagos reales
- Sin video upload: creadores no pueden subir cursos → $0 revenue
Entregable Q1: Plataforma segura y lista para pagos reales.
FASE 2: Core Features (Q2 2026) - 362h
Objetivo: Completar features comerciales vendidas.
| Feature | Epic | Esfuerzo | Revenue Potential | Prioridad |
|---|---|---|---|---|
| Live streaming educativo | OQI-002 | 80h | +30% engagement | P1 |
| WebSocket real-time trading | OQI-003 | 60h | -200ms latencia | P1 |
| LLM Streaming responses | OQI-007 | 40h | +20% satisfacción | P2 |
| Portfolio optimizer (Markowitz) | OQI-008 | 80h | Feature diferenciadora | P2 |
| MT4 Gateway funcional | OQI-009 | 180h | Feature vendida | P0 |
Justificación:
- MT4 Gateway: Feature prometida a clientes, 0% funcional

2. Recomendaciones para Engineering Lead
2.1 Deuda Técnica Crítica
Tier 1: BLOQUEANTES (Resolver Q1 2026)
| Issue | Ubicación | Impacto | Esfuerzo | Owner |
|---|---|---|---|---|
| Manual token refresh | authStore.ts:67 | 🔴 CRÍTICO | 60h | Backend + Frontend |
| PCI-DSS non-compliant | PaymentMethodForm.tsx | 🔴 LEGAL | 80h | Frontend + Legal |
| VideoProgressPlayer sin upload | modules/education/ | 🔴 FUNCIONAL | 60h | Frontend + Backend |
| MT4 Gateway stub | modules/mt4/ | 🔴 FUNCIONAL | 180h | Backend + MT4 Specialist |
Total Tier 1: 380 horas (~2.5 meses, 2 devs)
Tier 2: ALTO IMPACTO (Resolver Q2 2026)
| Issue | Ubicación | Impacto | Esfuerzo |
|---|---|---|---|
| OrderBookPanel polling | modules/trading/components/ | Performance | 40h |
| Sin Error Boundaries | apps/frontend/src/ | Reliability | 15h |
| Código duplicado (charts) | modules/*/components/ | Maintainability | 25h |
| VideoProgressPlayer 554 líneas | modules/education/components/ | Complexity | 12h |
Total Tier 2: 92 horas (~2 semanas, 1 dev)
2.2 Arquitectura - Decisiones Requeridas
Decisión 1: WebSocket Strategy
Problema: 3 implementaciones distintas de WebSocket (OrderBookPanel, MT4, LLM planned).
Opciones:
| Opción | Pros | Contras | Esfuerzo |
|---|---|---|---|
| A. Centralizar en WebSocketProvider | DRY, mantenible | Refactor 3 componentes | 60h |
| B. Dejar ad-hoc | No rompe código existente | Duplicación, bugs | 0h |
| C. Migrar a Socket.io | Features avanzados | Dep adicional (50KB) | 80h |
Recomendación: Opción A - Centralizar ahora antes de que haya más implementaciones.
Decisión 2: State Management - ¿Consolidar stores?
Problema: 9 stores Zustand (authStore, tradingStore, mlStore, etc.) con overlap.
Opciones:
| Opción | Pros | Contras | Esfuerzo |
|---|---|---|---|
| A. Consolidar en 3 stores (auth, data, ui) | Menos complejidad | Refactor masivo | 120h |
| B. Mantener granularidad | Code-splitting, scope claro | 9 stores mantener | 0h |
| C. Migrar a Redux Toolkit | DevTools, ecosystem | Overhead, curva aprendizaje | 200h |
Recomendación: Opción B - Zustand granular es correcto, solo optimizar authStore.
Decisión 3: Testing Strategy
Problema: ~15% coverage, sin E2E, CI/CD limitado.
Propuesta:
FASE 1 (Q1): Setup infrastructure (20h)
├─ Vitest configurado (unit)
├─ Playwright configurado (E2E)
└─ CI/CD pipeline (GitHub Actions)
FASE 2 (Q2): Critical paths (40h)
├─ Auth flow (login, logout, refresh)
├─ Trading flow (order creation, execution)
└─ Payment flow (checkout, subscription)
FASE 3 (Q3): Coverage 70% (120h)
├─ Unit tests componentes críticos
├─ Integration tests APIs
└─ E2E tests user journeys
Target: 70% coverage en Q3 2026.
2.3 Code Quality - Acciones Inmediatas
Refactor VideoProgressPlayer (12h - P1)
Problema: 554 líneas, 11 states, difícil mantener.
Solución:
// ANTES (554 líneas)
VideoProgressPlayer.tsx (monolito)
// DESPUÉS (refactorizado)
VideoProgressPlayer.tsx (200 líneas UI)
├─ useVideoPlayer.ts (custom hook, lógica)
├─ useBookmarks.ts (custom hook)
├─ useNotes.ts (custom hook)
└─ useVideoProgress.ts (custom hook)
Beneficios:
- Testing más fácil (hooks independientes)
- Reusabilidad (hooks en otros players)
- Mantenibilidad (+60%)
Desacoplar authStore (30h - P0)
Problema: 40 componentes dependen directamente de authStore.
Solución:
// ANTES
import { useAuthStore } from '@/stores/auth.store'
const user = useAuthStore(state => state.user) // 40x repetido
// DESPUÉS
import { useAuth } from '@/hooks/useAuth' // HOC intermedio
const { user, isAuthenticated, logout } = useAuth()
Beneficios:
- Cambios en authStore no afectan 40 componentes
- Testing con mock useAuth más fácil
- Abstracción para futuras migraciones
Implementar Error Boundaries (15h - P1)
Problema: 1 error JavaScript tumba toda la app.
Solución:
// Boundary por epic
<ErrorBoundary epic="OQI-003" fallback={<TradingErrorFallback />}>
<Trading />
</ErrorBoundary>
Beneficios:
- Errors contenidos (trading falla, educación funciona)
- UX mejor (fallback UI en lugar de pantalla blanca)
- Telemetry (reportar errores a Sentry)
2.4 Performance Optimizations
| Optimización | Métrica Actual | Target | Esfuerzo | ROI |
|---|---|---|---|---|
| WebP images | JPG/PNG (~100KB/img) | WebP (~30KB/img) | 20h | ALTO |
| Lazy loading | Bundle 2.5MB | Bundle 800KB | 30h | ALTO |
| Code-splitting | 1 chunk | 10 chunks (por epic) | 40h | MEDIO |
| Memoization | Re-renders innecesarios | React.memo en lists | 10h | MEDIO |
| Virtualization | Render 1000+ items | Virtualizar listas largas | 20h | MEDIO |
Total: 120h (~3 semanas, 1 dev) Impacto: FCP 3.5s → 1.5s, TTI 6s → 2.5s
2.5 Security Audit Findings
| Vulnerabilidad | OWASP | Severidad | Ubicación | Remediación |
|---|---|---|---|---|
| Tokens en localStorage | A02:2021 | 🔴 ALTA | authStore.ts:23 | Migrar a httpOnly cookies (40h) |
| No CSRF protection | A01:2021 | 🔴 ALTA | apiClient.ts | CSRF tokens (20h) |
| PCI-DSS non-compliant | PCI-DSS | 🔴 CRÍTICA | PaymentMethodForm | Stripe Elements (80h) |
| XSS en MarkdownRenderer | A03:2021 | 🟠 MEDIA | components/ | Sanitizar HTML (10h) |
| Rate limiting ausente | A04:2021 | 🟡 BAJA | Backend (no frontend) | Backend implementa (0h frontend) |
Acción Inmediata: Priorizar tokens + CSRF + PCI-DSS (140h total).
3. Recomendaciones para Frontend Developers
3.1 Standards y Convenciones
Convenciones de Naming (Obligatorias)
// ✅ CORRECTO
// Componentes: PascalCase
export const VideoProgressPlayer: React.FC = () => {}
// Hooks: camelCase con prefijo "use"
export const useVideoPlayer = () => {}
// Stores: camelCase con sufijo "Store"
export const authStore = create(() => {})
// Tipos: PascalCase con sufijo "Props" o "Type"
interface VideoPlayerProps {}
type SignalType = 'buy' | 'sell'
// Archivos: kebab-case
video-progress-player.tsx
use-video-player.ts
auth.store.ts
Component Structure (Template)
// 1. Imports
import React from 'react'
import { useAuthStore } from '@/stores/auth.store'
import { Button } from '@/components/ui/Button'
// 2. Types
interface MyComponentProps {
title: string
onSubmit: () => void
}
// 3. Component
export const MyComponent: React.FC<MyComponentProps> = ({ title, onSubmit }) => {
// 3.1 Hooks
const user = useAuthStore(state => state.user)
const [isLoading, setIsLoading] = React.useState(false)
// 3.2 Handlers
const handleClick = () => {
setIsLoading(true)
onSubmit()
}
// 3.3 Effects
React.useEffect(() => {
// ...
}, [])
// 3.4 Render
return (
<div>
<h1>{title}</h1>
<Button onClick={handleClick} disabled={isLoading}>
Submit
</Button>
</div>
)
}
3.2 Testing - Ejemplos Requeridos
Unit Test (Vitest + Testing Library)
// video-progress-player.test.tsx
import { render, screen, fireEvent } from '@testing-library/react'
import { VideoProgressPlayer } from './VideoProgressPlayer'
describe('VideoProgressPlayer', () => {
it('should play video when clicking play button', () => {
render(<VideoProgressPlayer src="test.mp4" />)
const playButton = screen.getByRole('button', { name: /play/i })
fireEvent.click(playButton)
expect(screen.getByText(/playing/i)).toBeInTheDocument()
})
it('should save bookmark at current time', () => {
const onBookmark = vi.fn()
render(<VideoProgressPlayer src="test.mp4" onBookmark={onBookmark} />)
// Simular tiempo 30s
const video = screen.getByTestId('video-element')
fireEvent.timeUpdate(video, { target: { currentTime: 30 } })
const bookmarkButton = screen.getByRole('button', { name: /bookmark/i })
fireEvent.click(bookmarkButton)
expect(onBookmark).toHaveBeenCalledWith(30)
})
})
E2E Test (Playwright)
// auth.spec.ts
import { test, expect } from '@playwright/test'
test.describe('Authentication Flow', () => {
test('should login successfully with valid credentials', async ({ page }) => {
await page.goto('http://localhost:3000/login')
await page.fill('input[name="email"]', 'user@example.com')
await page.fill('input[name="password"]', 'password123')
await page.click('button[type="submit"]')
await expect(page).toHaveURL('http://localhost:3000/dashboard')
await expect(page.locator('text=Welcome back')).toBeVisible()
})
test('should auto-refresh token before expiration', async ({ page }) => {
// Login
await page.goto('http://localhost:3000/login')
await page.fill('input[name="email"]', 'user@example.com')
await page.fill('input[name="password"]', 'password123')
await page.click('button[type="submit"]')
// Esperar 50 minutos (token expira en 60m)
await page.waitForTimeout(50 * 60 * 1000)
// Verificar que sigue autenticado (token refrescado)
await page.reload()
await expect(page).toHaveURL('http://localhost:3000/dashboard')
})
})
3.3 Code Review Checklist
Antes de enviar PR, verificar:
- TypeScript: Sin
any, interfaces definidas - Testing: ≥80% coverage del código nuevo

3.4 Common Pitfalls - Evitar
❌ NO HACER
// 1. Mutación directa de state
const user = useAuthStore(state => state.user)
user.name = 'New Name' // ❌ NUNCA
// 2. Fetch en render
const MyComponent = () => {
fetch('/api/data') // ❌ Causa loops infinitos
return <div>...</div>
}
// 3. Cualquier tipo "any"
const handleClick = (event: any) => {} // ❌
// 4. Inline functions en props (re-renders)
<Button onClick={() => console.log('click')} /> // ❌ (dentro de loop)
// 5. Ignorar keys en listas
{items.map(item => <Item />)} // ❌ Sin key
✅ HACER
// 1. Actualizar state inmutablemente
const updateUserName = useAuthStore(state => state.updateUserName)
updateUserName('New Name') // ✅
// 2. Fetch en useEffect
const MyComponent = () => {
React.useEffect(() => {
fetch('/api/data')
}, [])
return <div>...</div>
}
// 3. Tipos específicos
const handleClick = (event: React.MouseEvent<HTMLButtonElement>) => {} // ✅
// 4. useCallback para handlers
const handleClick = React.useCallback(() => console.log('click'), [])
<Button onClick={handleClick} /> // ✅
// 5. Keys únicas
{items.map(item => <Item key={item.id} {...item} />)} // ✅
