Who am I?

I'm a Computer Engineer with over 8 years of hands-on experience designing and developing robust Oracle NetSuite solutions to meet unique business needs. I graduated from the Instituto Tecnológico de Costa Rica (ITCR) and have been deep in the NetSuite ecosystem since 2019.

At Limebox, I design and implement NetSuite solutions that improve performance, automate processes, and solve complex operational challenges through custom scripting and integrations. I also run my own freelance practice, working with clients across Latin America and the United States.

What I specialize in

  • Custom business process automation using SuiteScript
  • NetSuite Field Service Management (FSM)
  • API development and third-party system integration
  • Performance optimization and system architecture
  • SuiteCloud (SDF) projects, Bundles, and deployments

Driven by a passion for embedded systems, automation, and continuous improvement, I focus on delivering practical solutions that make a measurable impact.

Beyond the code

Outside of work you'll find me designing parts for my Bambu Lab P2S, building gadgets with ESP32, or running experiments on the homelab. My background in embedded systems keeps me close to hardware — I find the intersection of software and the physical world endlessly interesting.
