What I'm looking for

I am seeking engineering roles that leverage CAD and manufacturing expertise, emphasize multidisciplinary collaboration, continuous learning, and sustainable, safety-focused project delivery.

Mechanical Engineer with hands-on experience in CAD design, CNC machining, and manufacturing processes, complemented by professional expertise in AI data annotation and LLM evaluation. Skilled in Autodesk Inventor, SolidWorks, AutoCAD, and Design for Manufacturing (DFM), with experience creating production-ready engineering drawings, mechanical assemblies, and technical documentation.

In addition to engineering, I have worked remotely on AI projects for companies including Mercor, RWS, and Trace Up, evaluating AI-generated responses, annotating text, image, and audio datasets, and performing quality assurance with consistently high accuracy. I thrive in detail-oriented, analytical roles that require precision, problem-solving, and continuous learning.

I'm open to remote opportunities in mechanical engineering, CAD design, AI data annotation, quality assurance, technical operations, and other engineering-related roles where I can combine technical expertise with strong analytical and communication skills.
