Who I Am

I Design Systems
From Scratch

Computer Engineering student at Tecnológico de Costa Rica focused on backend architecture, data systems, and production infrastructure.

My projects simulate real startup environments: distributed systems, scraping pipelines, ETL workflows, ML microservices, and cloud-native deployments.

Production Systems

15+

Technologies

100%

Architecture First

class SystemArchitect:

  def design(self):
    self.db = "PostgreSQL"
    self.api = "FastAPI"
    self.auth = "JWT + OAuth"
    self.deploy = "Docker + CI/CD"

  def ship(self):
    pipeline = ETL.build()
    api = self.api.start()
    return "Production Ready"
