We develop, debug, and improve firmware for connected devices, sensors, battery-powered products, and custom hardware. From board bring-up to RTOS, drivers, wireless integration, OTA updates, and low-power optimization.
Good embedded firmware is not just application logic. It has to respect the hardware: timing, power rails, boot sequence, interrupts, radio events, sensors, flash wear, watchdogs, and failure recovery. We build firmware with those constraints in mind.
Hardware Startups: Rapidly transition from breadboard prototypes to production ready C/C++ architecture.
IoT Companies: Scale secure device fleets with stable connectivity and seamless Over the Air (OTA) updates.
Medical Device Manufacturers: Build deterministic, IEC 62304-compliant firmware for mission critical hardware.
Industrial Automation Companies: Implement low latency CAN, Modbus, and EtherCAT protocol stacks for heavy machinery.
Consumer Electronics Brands: Maximize responsiveness while driving power consumption down to microamps.
Robotics Companies: Engineer real time task scheduling and motor control driver loops.
Most firmware problems do not look dramatic at first.
A device works on the bench but fails after a few hours. A BLE connection drops randomly. Sleep current is higher than expected. A sensor sometimes returns bad data. OTA works nine times and fails on the tenth.
We help isolate these issues across firmware, hardware, timing, power, and wireless behavior, then fix them without rewriting everything from scratch.
We usually start by understanding the hardware, firmware state, and the failure mode.
Then we reproduce the issue, inspect logs, signals, and current traces where needed, isolate whether the problem is firmware, hardware, timing, power, or wireless behavior, and implement the fix in small testable steps.
For new development, we define the firmware architecture early: drivers, RTOS tasks, communication interfaces, update flow, error handling, and recovery behavior.
Weak Architecture: Unstructured spaghetti code leads to unmaintainable systems. Mitigation: We enforce strict state-machine designs and clean HAL layers.
Memory Leaks: Dynamic allocation ($malloc$) on embedded devices causes unpredictable crashes. Mitigation: We mandate static memory allocation policies.
Interrupt Conflicts: Long ISR routines block high-priority system tasks. Mitigation: We keep ISRs ultra-lean and defer heavy work to RTOS tasks.
Lack of Hardware Testing: Testing on simulators alone misses real-world electrical timing issues. Mitigation: Automated Hardware-in-the-Loop (HIL) test suites run on physical hardware.
The result is firmware that is easier to test, debug, update, and maintain.
Your hardware gets stable drivers, cleaner task structure, better recovery behavior, lower power consumption where needed, and fewer unknowns before release.
For teams with existing firmware, we can step in to fix specific issues without forcing a full rewrite. For new products, we can help build the firmware foundation from prototype to production-ready release.
