Top Rated Plus optical engineer ($200K+ earned, 100% JSS) who now pairs 25 years of lens, laser, and illumination design with modern AI/ML — so your optical product gets designed AND its imaging, inspection, or design-optimization intelligence built by one engineer.
What I do:
• Optical & lens design — imaging, laser, LED/illumination systems in Zemax OpticStudio, concept to high-volume production
• Computer Vision & image processing — hardware simulation for the software AI/ML integration
• Physics-informed ML & inverse design — surrogate models and ML-accelerated optimization for Zemax/Lumerical/FRED design loops
• End-to-end delivery — in-house 3D printing, CNC, laser scanning, and lighting measurement, plus a vetted prototype-to-production fabrication network
How I work: fixed-price or hourly with a clear, milestone-based scope. Inventive, confidential, and embedded alongside your product team. No surprises.
Ideal for teams building cameras, sensors, EO/IR systems, medical/endoscopic optics, or inspection hardware who need both the optics and the AI in one trusted US-based expert.
Message me with your goal and I'll send a short written plan and fit check.

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.
