Flexibility
Engagement Models
Flexible arrangements based on your needs. Every engagement starts with a technical discussion—no sales pitch, just engineering.
Technical Consultation
Architecture review, feasibility analysis, technology selection, troubleshooting existing systems.
Subsystem Development
Design and deliver a specific component: a power supply, a sensor interface, a communication module.
Complete Product Development
End-to-end: requirements to deployed product. Hardware, firmware, software, documentation.
Ongoing Technical Support
Maintenance, updates, production support for deployed systems.
Investment
Flexible Engagement
Custom Quotes
Pricing based on project scope, complexity, and timeline. No hourly tracking—just clear milestones and deliverables.
Higher investment:
- High-power or safety-critical systems
- On-site work with travel requirements
- Overnight stays or extended deployments
- Extensive client hand-holding required
- Tight deadlines or parallel priorities
More competitive:
- Interesting technical challenges
- Long-term engagements
- Clear requirements and documentation
- Remote-first work
- Flexible timelines
Fixed-price for defined projects. Retainer for ongoing work. International clients welcome—competitive rates globally.

Process
How It Works
Technical Discussion
We talk about your project, your constraints, and your goals. I ask questions. You get honest feedback on feasibility, timeline, and approach. No sales pitch.
Scope & Estimate
Based on our discussion, I provide a detailed scope document with timeline, milestones, and cost estimate. Clear deliverables, no ambiguity.
Development
Regular updates. Working demos at milestones. Direct communication—you're talking to the engineer doing the work, not a project manager.
Delivery & Handoff
Complete deliverables: source code, hardware files, documentation. Knowledge transfer to your team if needed. Post-delivery support included.
