- **Cache:** Redis 7
- **Auth:** JWT + Passport.js (local, OAuth2)
### AI/ML Services (Python)
- **ML Engine:** FastAPI + PyTorch + XGBoost + scikit-learn
- **LLM Agent:** FastAPI + Ollama (Llama 3.1, Qwen 2.5)

## Key Design Decisions
### 1. Microservices Architecture (Heterogeneous)
**Decision:** Separar servicios por lenguaje según especialización.
**Rationale:**
- Node.js para API y web (mejor I/O async)
- Python para ML/AI (ecosistema superior: PyTorch, scikit-learn, CCXT)
- Escalabilidad independiente por servicio
- Equipos especializados por stack
**Trade-offs:**
- Mayor complejidad operacional
- Necesita orquestación (Docker Compose)
- Múltiples runtimes (Node.js + Python)
### 2. Multi-Agent Trading System (Atlas, Orion, Nova)
**Decision:** 3 agentes con perfiles de riesgo diferenciados.
**Rationale:**
- Diversificación de estrategias
- Atractivo para diferentes tipos de inversionistas
- Competencia interna mejora algoritmos
**Profiles:**
- **Atlas (Conservador):** Target 3-5% mensual, max drawdown 5%
- **Orion (Moderado):** Target 5-10% mensual, max drawdown 10%
- **Nova (Agresivo):** Target 10%+ mensual, max drawdown 20%
### 3. Ensemble ML Models (CNN + LSTM + XGBoost)
**Decision:** Combinar múltiples modelos para detección AMD (Smart Money).
**Rationale:**
- CNN detecta patrones visuales en charts
- LSTM captura series temporales
- XGBoost para features tabulares
- Ensemble reduce overfitting
**Accuracy:** ~75% en backtesting (2020-2024)
### 4. Local LLM with Ollama
**Decision:** Usar Ollama para deployment local de LLMs (Llama 3.1, Qwen 2.5).
**Rationale:**
- Privacidad (no enviar datos a APIs externas)
- Costos predecibles (no pagar por token)
- Latencia baja
- Control total sobre modelos
**Trade-off:** Requiere GPU para inference rápida
### 5. PAMM (Percentage Allocation Management Module)
**Decision:** Implementar sistema PAMM para inversión colectiva.
**Rationale:**
- Permite a usuarios sin conocimiento invertir con los agentes
- Comisiones por performance (incentiva buenos resultados)
- Escalabilidad del modelo de negocio
**Status:** 60% implementado
### 6. Gamified Education Platform
**Decision:** Gamificar cursos de trading con puntos, logros y rankings.
**Rationale:**
- Aumenta engagement
- Acelera aprendizaje
- Atrae usuarios jóvenes
- Diferenciador vs competencia
### 7. PostgreSQL with Schema-based Multi-tenancy
**Decision:** Usar schemas PostgreSQL para separación lógica.
**Rationale:**
- Aislamiento claro por dominio
- Facilita migraciones por schema
- Mejor organización que tablas planas
- RLS (Row-Level Security) para multi-tenancy futuro
