Hello, I am Caesar Wiratama, a dedicated full-time Computational Fluid Dynamics (CFD) freelancer. I provide on-demand or outsourcing CFD consulting services.

I have been using Computational Fluid Dynamics and provided services since 2013, for individual research projects or large companies who want to solve their in-field problems or developing a new product.

The Industries are varying from Aerospace, energy and renewable energy, oil and gas, manufacturing, chemical processing or plant, automotive, HVAC, construction, biomedical engineering, or even new and state of novel multiphysics cases.

You can contact me via freelancer platform Upwork or Linkedin.
