Please make sure you open the attachments in the proposal. Few engineers have done single-handed such high level design/development in such wide range of fields as I. Also, technical problems that I have resolved via analysis/design/prototyping had been declared "impossible" or "unsolvable" by industry experts.
I am an experienced mechanical designer with analysis capabilities. I can take a design from conception, design, analysis, fabrication and development. I have particular experience in lubrication, sealing, and automotive engineering. I hold a PhD in Mechanical Engineering. In addition to CAD software/FEA, I have expertise in Matlab based modeling, ranging from dynamics, energy integration, to thermodynamics.

I help companies design, prototype, and troubleshoot complex hardware systems, especially where mechanical, electrical, thermal, and control systems must work together reliably in demanding real-world environments.
I am a former Head of R&D at Northrop Grumman Marine Systems, with experience in turbines, generators, electric motors, rotating machinery, and large-scale power systems. My work also includes combustion systems, battery systems, power electronics, embedded hardware, and full product development from concept through working prototype.
I work with startups and established companies on:
- hardware system design
- rotating machinery and power systems
- combustion, thermal, and fluid systems
- battery and embedded hardware
- controls, instrumentation, and industrial automation
- diagnosing and solving difficult engineering problems
I focus on practical, buildable solutions with strong attention to reliability, manufacturability, safety, and system integration. I’m often brought in when a project needs senior-level engineering direction to move from concept to a working system efficiently.
I studied engineering and business at Stanford University and have 20+ years of experience working with venture-backed startups, helping connect engineering decisions to product development, scaling, and execution.

I bridge the gap between rigorous engineering physics and fast-paced product development.
As a PhD Mechanical Engineer and startup founder, I offer a rare combination of deep theoretical knowledge and practical, hands-on building experience. I don't just design parts in CAD. I engineer complete systems by handling the mechanical design, optical integration, thermal analysis, and the Python code that makes it all run.
Whether you need to design a rugged sensor enclosure, automate a testing setup, or model a complex physical system, I bring the "Founder’s Mindset" to your project. I prioritize robust, manufacturable solutions that fit your timeline and budget.
My Multi-Disciplinary Expertise:
1. Mechanical Engineering & DFM I take concepts from napkin sketches to mass production. My designs are built for the real world, not just the computer screen.
Tools: Expert in SolidWorks and Fusion 360.
Capabilities: Design for Manufacturing (CNC, Injection Molding, 3D Printing), GD&T, and complex assembly management.
Experience: Engineered high-pressure sensor housings (10,000 psi / 250°C) and solar concentrator modules that survive outdoor elements for 20+ years.
2. Optomechanics & Precision Instrumentation: If your product involves light, lasers, or sensors, I am the specialist you need. I understand how mechanical stress affects optical performance.
Experience: Designed and built a sub-micron alignment workstation for fiber-to-chip attachment using high-power CO2 lasers.
R&D: Developed novel photonic sensors (published in Seismological Research Letters and Applied Optics), proving my ability to develop and handle extremely sensitive instrumentation.
3. Engineering Computation (Python & FEA) I use code and simulations to validate hardware. I rely on calculation rather than guesswork.
Simulation: Advanced Finite Element Analysis (ANSYS/COMSOL) for thermal, structural, ray/wave optics and multiphysics problems.
Python: Proficient in NumPy, SciPy, and Pandas for data analysis and physics-based modeling.
Automation: I build custom GUIs (Tkinter) to interface with hardware and automate data acquisition.
Why Clients Trust Me:
I have built my own company: As a founder in the renewable energy sector, I treat your capital with the same respect I treat my own. I focus on viable, scalable engineering.
I solve the "Hard" problems: I specialize in projects where standard engineering isn't enough, such as those involving extreme temperatures, high pressures, and sub-micron tolerances.

Hello and welcome to my profile!
I’m a mechanical engineering student specializing in CAD design, FEA simulations, and prototype development. I help clients turn ideas into clear 3D models, engineering drawings, and 3D-printable parts using SolidWorks and ANSYS. Recently I’ve designed and prototyped a circular-correction mechanism for industrial aerospace rings, studied vibration and thermal behaviour of an automotive brake disc, and created several functional assemblies and housings ready for fabrication.
Here’s what I can help you with:
* 3D modeling of parts and assemblies from sketches, photos, or ideas
* Manufacturing-ready drawings with dimensions and basic GD&T
* STL/STEP files for 3D printing and CNC machining
* Basic FEA (static, modal, and simple thermal) to validate designs
* Fast communication, clear documentation, and revisions until you’re satisfied
If you need a reliable, detail-oriented CAD designer for student, hobby, or entry-level industry projects, I’d be glad to work with you.
