Connected Embedded Devices (IoT)
Small to medium wireless/wired connected devices - from concept to working product. Focus: devices that ship in 1-6 months. I build complete systems: hardware, firmware, connectivity, mobile apps, and backend. One person, no handoff gaps.
Why Choose This Service
Complete integration:
PCB design, firmware, mobile apps, cloud backend - no handoff gaps between hardware and software specialists.
Production experience:
Shipped 1000+ units of my own product. I know the full journey: component selection, PCB layout, vendor negotiations, certification, production assembly.
Modular approach:
Using proven modules reduces development time, certification costs, and technical risk.
Overview & Details
Rapid hardware validation using proven dev boards. Go from concept to working prototype in 6-10 weeks without custom PCB investment. Perfect for testing with real users and proving technical feasibility before production.
The validation app demonstrates your device is fully connected end-to-end. Your team can build on this foundation, or we can develop the production app through our Full-Stack Applications service.

Post-Delivery Support
30-day critical bug fixes included: Best effort timeline, excludes new features or scope changes. Covers issues directly related to delivered functionality.
Certification & Compliance Pricing
Important: Certification work (CE/FCC/RED/etc) is billed hourly, not included in fixed project price.
Why hourly? Lab timelines are unpredictable, and requirements vary significantly by product/market.
Hourly rate includes:
- •Up-to-date regulatory research
- •Pre-compliance testing and preparation
- •Lab coordination and liaison
- •On-site support during testing
- •Documentation preparation
- •Travel expenses (if required)
Lab fees: Paid directly to certification bodies (you pay labs, I coordinate)
Estimate: Typical CE/FCC certification runs 100-200 hours of coordination work + lab fees (15-40k EUR paid to labs)
