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. WHAT I CAN HELP YOU WITH CFD & FLUID FLOW • Heat exchangers and thermal systems • Centrifugal fans, blowers, impellers, and volutes • HVAC, ducts, plenums, and airflow distribution • Electronics and enclosure cooling • Refrigerant and thermodynamic systems • Pressure-drop and flow-network optimization • Conjugate heat transfer • Natural and forced convection • Multiphase flow and species transport • Rotating machinery using MRF or transient methods • Turbulence modelling including k-ω SST, realizable k-ε, and LES where appropriate FEA & STRUCTURAL ANALYSIS • Static structural analysis • Stress and deformation • Fatigue and durability • Nonlinear materials and contact • Drop, impact, and shock analysis • Modal and vibration analysis • Buckling • Pressure vessels and pressure-containing components • Composite structures • Topology and weight optimization • Bolted, welded, and bonded assemblies CAD & PRODUCT DEVELOPMENT • SOLIDWORKS parametric modelling • Complex assemblies • Surface modelling • Sheet metal and weldments • Injection-moulded components • Machined and cast parts • Design for Manufacturing and Assembly • Tolerance analysis • Production drawings • Prototype development • Manufacturing-ready CAD packages THERMAL & NVH • Electronics cooling • Heat sinks and cold plates • Liquid cooling • Heat exchangers • Thermal resistance optimization • Fan and airflow acoustics • Noise and vibration investigation • NVH analysis 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. MULTIPHASE BRINE–CO₂ FLOW & CORROSION MODELLING Developing multiphase CFD models for oil-field pipework incorporating species transport and operating-condition sensitivity to understand flow behaviour and corrosion-critical regions. USC-APPROVED BACKFLOW VALVE Performed CFD pressure-loss validation across six valve configurations for a backflow-prevention system developed around AWWA C510 requirements. 32-MONTH PRODUCT-DEVELOPMENT ENGAGEMENT Served as Principal Mechanical Engineer on a long-term product-development program covering CAD, thermal engineering, mechanical design, prototyping, testing, and manufacturing support. ADAPTIVE AIRLESS TYRE Completed coupled structural and thermal feasibility analysis of a patented adaptive airless tyre using nonlinear FEA, CalculiX, and Gmsh. UNIVERSITY WIND-TUNNEL DEVELOPMENT Performed CFD development of a wind-tunnel contraction section, achieving less than 1% RMS velocity-profile variation within the working section. ELECTRONICS COOLING & THERMAL SYSTEMS Designed and analysed cooling architectures for compact electronics, enclosed computing systems, heat exchangers, cold plates, fans, and forced-convection systems.
