About Me
I'm a mechanical engineer working in the pipeline sector, from field operations to design.
Upstream, I've worked Wireline and TCP jobs — assembling tools, handling explosives, and supporting perforation operations on site. Midstream, I've covered pipeline design, construction support, and integrity work, from wall thickness calculations to walking spreads during hydrotesting.
For simulation and design I use Ansys and SolidWorks, along with pipeline tools like PIPSIM, Pipeline Studio, and OLGA for flow modeling and feasibility studies. Ansys was also the basis of my Bachelor's thesis.
