What I'm looking for

I’m seeking junior roles in mechanical design, maintenance, or reliability engineering, and I’m open to remote work and relocation.

Mechanical engineering student at Universidad Metropolitana (Caracas), graduating in March 2027, with two internships at Empresas Polar, one of Venezuela’s largest food and beverage manufacturers.

For my thesis I designed a gravity-driven inspector that removes defective PET preforms before they reach a 25,200 bottles/hour blow molder. I took it from on-site measurements and reverse engineering through FEA and CFD validation in SolidWorks to fabrication with a machine shop, and the prototype passed initial tests on the production line. I’ve also built a condition-based maintenance plan in SAP and run CFD studies of a centrifugal pump in STAR-CCM+.

Tools: SolidWorks (CAD, FEA, Flow Simulation), Fusion 360, STAR-CCM+, AutoCAD, MATLAB, Python, SAP. Fluent in English (C2) and native Spanish.

Open to remote work in mechanical design, CAD and simulation, or maintenance and reliability engineering, part-time now and full-time from 2027.

Mechanical Engineering Intern

Empresas Polar

Aug 2025 - Feb 2026 (6 months)

Developed a preform inspection system from on-site line measurements to supplier-ready drawings. Proposed a snap-on to threaded lid conversion for the vinegar bottle line, including line changes, costs, and data sheets. Validated the inspector with FEA and CFD in SolidWorks; the prototype passed initial production-line tests.
