Mechanical Engineer | CFD · FEA · CAD | 3× USPTO Patents | Top Rated Plus
CFD, FEA, thermal engineering, and advanced mechanical product development — from first-principles calculations and CAD through simulation, optimization, prototyping, and manufacturing-ready design.
I am a Mechanical Engineer and Top Rated Plus Upwork freelancer with $250K+ earned, 130+ completed contracts, 3,000+ hours, and extensive experience solving complex engineering problems for startups, manufacturers, R&D teams, and established technology companies.
My work spans CFD, FEA, thermal management, turbomachinery, HVAC, electronics cooling, aerospace, automotive systems, pressure equipment, product development, and manufacturing.
I am also an inventor on USPTO-granted cooling-system technology, including US 12,452,991 and US 12,453,048.

WHY CLIENTS HIRE ME
I do not provide black-box simulations with screenshots and a “trust me” conclusion.
My simulation work is built so that your engineers, investors, manufacturers, or certification teams can understand and defend the results.
Depending on the project, deliverables can include:
• Mesh-independence and convergence evidence
• Y+ verification
• Residual histories
• Boundary-condition justification
• Analytical or experimental validation
• Pressure, velocity, temperature, stress, and deformation plots
• Flow-uniformity analysis
• Parametric design comparisons
• Design recommendations
• Manufacturing implications
• Executive engineering summaries
• Native simulation and CAD files
For optimization-heavy projects, I also use Python-driven automation with OpenFOAM and other solvers to evaluate design spaces far beyond what is practical using manual simulation workflows.
SELECTED ENGINEERING WORK
224,000-POINT CFD OPTIMIZATION — HEAT EXCHANGER
Built an automated CFD optimization workflow for a centrifugal heat-exchanger architecture. A 224,000-point design-space sweep identified geometry changes capable of more than doubling predicted system COP.
