Every hardware decision made today affects manufacturing cost, certification, battery life, reliability, and time to market.
That's where I come in.
I work with startups, R&D teams, and product companies to make the critical engineering decisions before they become expensive problems. Rather than simply drawing schematics or routing PCBs, I help design products that are manufacturable, reliable, scalable, and ready for real-world deployment.
Whether you're building your first prototype or preparing for production, I can help you move faster with confidence.

My Engineering Philosophy
I don't believe great hardware is built by selecting expensive components.
Great hardware comes from making the right engineering trade-offs.
Every recommendation I make balances:
• Performance
• Reliability
• Cost
• Manufacturability
• Power Consumption
• Product Lifetime
• Supply Chain Availability
• Future Scalability
This approach helps reduce redesign cycles while making products easier to manufacture and maintain.
What You Can Expect
From our first conversation, I focus on understanding:
• What you're building
• Who will use it
• Where it will operate
• What constraints matter most
Then I provide practical engineering solutions—not unnecessary complexity.
You receive clear documentation throughout the project, making collaboration with firmware teams, mechanical engineers, manufacturers, and certification labs much smoother.
Deliverables
• Hardware Architecture
• System Block Diagrams
• Schematics
• PCB Layout
• Gerber Files
• Pick & Place Files
• Assembly Drawings
• Bill of Materials (BOM)
• 3D PCB Models
• Component Libraries
• Design Review Reports
• Manufacturing Documentation
• Prototype Bring-Up Support
• Test Plans & Validation Documents
Selected Projects
• Precision Drug Delivery Device (Medical)
• Bone Density Measurement System
• EMG Wearable Diagnostic Device
• Smart Health Monitoring Ring

Why Clients Hire Me
• I think like a product architect—not just a PCB designer.
• I identify design risks before they become manufacturing issues.
• I communicate clearly with founders, engineers, and manufacturers.
• I document every important engineering decision.
• I care about long-term product reliability—not just completing the next milestone.
• I stay involved until the hardware works as expected.
