Jose Eduardo Tirado Verbel · jotive.dev

Backend Engineer — Python · TypeScript · AI Integration

Backend engineer con 6+ años construyendo APIs y servicios que llegan a producción. Foco en diseño de API con trade-offs explícitos (cada decisión documentada como ADR), microservicios multi-tenant en Google Cloud, e integración real de LLMs en flujos de negocio.

Notas técnicas y proyectos en dev.jotive.com.co.


What I build

Production APIs

  • REST con idempotency keys (Postgres unique + Redis lock), cursor pagination, rate limiting con token bucket Lua atómico, errores RFC 7807
  • Microservicios multi-tenant en Cloud Run con signed URLs (GCS) y convención de keys por tenant
  • Cada decisión técnica como Architecture Decision Record con alternativas rechazadas

AI Integration (aplicado, no investigación)

  • Pipelines con Anthropic Claude Sonnet (incluyendo visión sobre URLs remotas) con manejo de quota y abort temprano en lugar de retry bobo
  • Integración OpenAI Chat Completions dentro de pipelines FastAPI
  • Clasificación de señales con LLM sobre datos scrapeados

Infra

  • Bash idempotente para hardening de VPS (sshd, fail2ban, systemd user con CPU/RAM limits)
  • Docker multi-stage + Compose como interfaz estándar
  • CI/CD con GitHub Actions
