Embedded systems that just work.
Reliably.
For years.

Product is behind schedule? Firmware contractor ghosted? Hardware isn't performing?
That's where we start.

We think about your product the way a CTO would: market fit, maintainability, what happens two years from now, while writing the register-level code ourselves.

End-to-End Product Development Expertise

We don't just write code - we design complete solutions that integrate seamlessly with your hardware architecture.

Embedded Firmware Development

Full product firmware from bare metal to RTOS. Authors of TaskScheduler: 1,600+ GitHub stars, shipping in commercial products worldwide.

Electrical Engineering

Hardware/firmware co-design, schematic review, PCB guidance. We've rescued products by identifying hardware fixes that made broken designs shippable.

System Integration

BLE stacks, cloud backends (AWS IoT), mobile app integration. We own the full embedded side from prototype through production.

Performance Optimization

2 months runtime on a 150mAh battery. Reliable BLE under 30-second response. We optimize where it actually matters.

Security & Encryption

MCUboot secure boot, encrypted OTA pipelines, device provisioning systems. Every product we ship is field-updatable from day one.

IoT Consulting

Architecture-level guidance from a team with CTO-level experience (BLADE, EagleEye Systems). We help you make technology decisions that scale beyond v1.

How We Work

Milestone-Based Delivery

You see working firmware at every stage, not a big reveal at the end. If something needs to change direction, you find out in week 2, not month 4.

Built for Independence

Every project ships with OTA architecture. After delivery, you can push updates to devices in the field without calling us back. We build ourselves out of the dependency chain on purpose.

Architecture-Level Thinking

CTO-level experience managing large engineering teams. When we design your firmware, we're thinking about manufacturing scale, field serviceability, and your next product generation.

Clinical and Regulated Experience

Firmware that passed clinical testing. BLE SIG qualification process. We know what 'production-ready' means when certification is on the line.

Recent Commercial Successes

SmartCuffs

Full firmware development across multiple generations: clinically validated LOP algorithm, BLE stack, mesh OTA, and device provisioning. Long-term collaboration now in its 4th generation.
