Firmware architecture
Define operating modes, module boundaries, state machines, data flow, timing, and interfaces before implementation. Specify normal operation, edge cases, and failure behavior.
Firmware & software development
Read the world.
Run the logic.
Make it respond.
Software for physical products: embedded control, device communications, companion applications, and the services that connect them.
From the first sensor reading to a complete product workflow, we develop and test the code alongside the hardware it controls and the people who use it.
01 / Behavior first
From pinout to user experience.
A responsive interface depends on the complete system: mechanics, electronics, firmware, applications, networks, and services.
Low-level development
Develop drivers, control logic, algorithms, and communications for the selected MCU, processor, PLC, or programmable-logic platform. Work from the schematics, pinout, buses, interrupts, and peripheral limits.
Applications and connected services
Build mobile, desktop, and web applications, including browser interfaces and server-side services. Connect device status, commands, APIs, cloud services, and production tools around the product workflow.
Bring-up on real boards
Exercise sensors, actuators, displays, power systems, and communication modules on physical hardware. Investigate timing, noise, unstable power, and interactions that a simulation or desktop test can miss.
Edge AI and sensor integration
When inference belongs on the device, consider sensor placement, compute selection, memory, power budget, response time, and how the output changes product behavior. Integrate edge inference and evaluate it within the intended use case.
Cost-conscious implementation
Compare module convenience with component cost, engineering effort, performance, and long-term support. Use firmware to close a functional gap when the overall trade-off makes sense.
02 / Technical scope
Code close to the machine.
The implementation can span embedded firmware, application software, and connected infrastructure. Platform and stack choices follow the product requirements.

03 / From first signal to product
Build the behavior in stages.
We agree on the operating modes and acceptance checks for each increment, then test the implementation against them.
- 01
Proof of concept
Can the core principle work?
An early electronics mockup or bench setup demonstrates basic sensing, control, or communication.
Focus: Core logic, signal reading, actuator response, and technical feasibility.
What you receive: Demonstration firmware, observations, and the next technical decisions.
- 02
Functional prototype
Does it work on real hardware?
The main operating modes run on the custom PCB or integrated electronics sample.
Focus: Board bring-up, interfaces, timing, power behavior, and peripheral testing.
What you receive: A reproducible build and evidence from the agreed hardware checks.
- 03
Integrated prototype
Does it behave as a complete product?
An assembled engineering prototype performs full workflows with error handling and repeatable test results.
Focus: System integration, connectivity, recovery logic, calibration, and test modes.
What you receive: Tested device workflows and the required application or service interfaces.
- 04
Pilot-ready device
Can it operate in the intended environment?
The hardware and embedded software are exercised in real or representative use conditions.
Focus: Field validation, QA workflow, production-test preparation, and documentation.
What you receive: A release candidate, deployment instructions, and a defined list of open issues.
04 / Beyond the happy path
The awkward moments matter.
Startup, shutdown, retries, disconnected networks, faults, and recovery shape how dependable a product feels.
Hardware-aware control
Account for power domains, pull-ups, ADC behavior, interrupts, and bus constraints. Motors, pumps, valves, buttons, airflow, and the enclosure can all change how the control logic should behave.
A coordinated product experience
Align device commands, status reporting, application feedback, and cloud APIs. Define timing and state transitions so the interface reflects what the physical device is actually doing.
Diagnostics and updates
Plan fault logging, watchdogs, safe modes, update integrity, and recovery. Where remote updates are in scope, address deployment, rollback, and the behavior of interrupted updates.
Maintainable across revisions
Use modular, documented code and stable interfaces to accommodate feature changes, new components, and future variants. Define build inputs and test procedures so another engineer can continue the work.
Security requirements belong in the architecture. See Device security & assessment for secure development, review, and testing.
05 / Source to support
Keep building after delivery.
A binary alone is rarely enough. We define the files, instructions, and support arrangements needed for your next step.
- Source and architecture: agreed firmware and application source code, module descriptions, state definitions, pin maps, and interface documentation.
- Reproducible builds: toolchain and dependency versions, configuration, build instructions, and release artifacts.
- Testing: relevant automated tests, hardware test procedures, integration results, known defects, and limitations.
- Deployment: flashing, provisioning, installation, updates, and recovery instructions appropriate to the scope.
- Continuity: maintenance notes, third-party license information, and agreed arrangements for post-delivery support.
