Common Challenges
We Understand IoT Engineering
IoT systems span hardware, firmware, edge, and cloud, and they fail in the seams. The challenges we help connected product teams work through.
Connectivity & Protocol Diversity
The protocol choice is upstream of half the product roadmap. BLE saves battery but constrains range. LoRaWAN gives you kilometers but kilobytes. LTE-M solves coverage but adds a recurring carrier bill per device. The wrong call shows up as a hardware revision twelve months in, not as a software change.
Edge Computing Constraints
Most IoT devices spend 99% of their life asleep. Hitting a five-year battery target on a coin cell means duty cycling measured in milliseconds per hour, peripheral power gating, and being honest about what cannot run on-device at all. Adding 'a small ML model' to a sleeping device is rarely small.
Device Management at Scale
A successful product is a million bricked devices waiting to happen. OTA needs cryptographic signing, A/B partitions or fail-safe rollback, staged rollout with health gates, and differential bundles for cellular fleets. The OTA design you ship in v1.0 is the constraint you cannot fix in v1.1, because v1.1 has to flash over v1.0.
Security at the Device Level
Every device shipped is an internet-facing host that will outlive your security team's attention span. Secure boot from a hardware root of trust, factory provisioning that gives each unit a unique identity it cannot leak, mutual TLS, and a certificate rotation strategy that survives a vendor change are baseline. The recall cost of getting this wrong is the device, not the firmware.
What We Build
IoT Engineering Capabilities
Engineering capabilities for device firmware, edge computing, IoT cloud backends, and connected fleets at scale.
Firmware & Embedded Development
C and C++ firmware on ARM Cortex-M, ESP32, STM32, and nRF52 with FreeRTOS, Zephyr, or bare-metal as the application demands. Power profiling against real-device telemetry, OTA from day one (not as a v2 retrofit), and a HAL boundary that makes a chip family swap a contained change rather than a re-port.
Cloud IoT Backends
Telemetry ingestion that survives a fleet-wide reconnect storm, device shadow and digital twin services, time series storage in TimescaleDB or InfluxDB sized to your actual write rate, and rule-engine alerting that the support team can edit without a redeploy. AWS IoT Core, Azure IoT Hub, or a custom EMQX broker when the math says so.
Device Management Platforms
Fleet dashboards that answer the operator question (which units are unhealthy, since when, on what firmware), OTA rollouts with cohorting and automatic abort on health regression, remote configuration with audit history, and zero-touch factory provisioning workflows the manufacturing line can actually run.
IoT Mobile & Web Applications
Companion apps with BLE provisioning that does not crash on Android Bluetooth quirks, control dashboards that degrade usefully when a device goes offline, and analytics views for the rare end user who actually opens the data tab. Apple HomeKit, Google Home, and Alexa integrations where they earn their keep.
IoT Security Architecture
Threat modeling against the actual device, not a generic PSA. Secure boot from a hardware root of trust, a private CA strategy that does not break when the vendor relationship does, mutual TLS at provisioning, and certificate rotation tested by actually rotating them before launch.
Edge AI & Predictive Analytics
TensorFlow Lite Micro and ONNX Runtime models quantized to int8 and pinned to a memory budget you can actually meet on a Cortex-M, with an honest answer about when the right call is to send the data to the cloud instead. Anomaly detection and predictive maintenance are the usual fits.

Technologies We Use
The C, C++, MQTT, AWS IoT Core, and Azure IoT Hub tooling we reach for on production IoT work.
Compliance & Standards
Built to Meet Regulations
Engineering practices aligned with IEC 62443, ETSI EN 303 645, FCC Part 15, and the security controls IoT buyers will audit.
The Software Pro Difference
Why Choose Software Pro
The reasons engineering leaders keep coming back, told the way we'd tell them in the room.
Full-Stack IoT Engineering
One team owns firmware, edge software, cloud backend, and the companion app. No handoff gaps where firmware blames cloud and cloud blames firmware.
Security Designed In, Not Retrofitted
Secure boot, per-device identity, and mutual TLS from day one. Security bolted on after deployment is the failure mode that ends in a recall.
30+ Connected Products Shipped
We have seen what breaks between prototype and scaled fleet. OTA, certificate lifecycle, and factory provisioning are in scope, not afterthoughts.
OTA Built Into v1.0
The OTA architecture you ship in v1.0 is the constraint you are stuck with in v1.1. We build it properly at the start, when it is still a design decision.
US Time Zone Alignment
6 to 8 hours of daily overlap with every US timezone. When a device fleet issue surfaces at scale, your team can reach ours in real time.
Certification Experience Included
FCC, CE, and carrier approval timelines are part of every project plan from kickoff. Certification is not a phase that gets discovered at the end.
Our IoT Engagement Process
A delivery process built for connected products, where firmware, edge, and cloud have to ship together and certification timelines are non-negotiable.
Hardware and Connectivity Review
We review your hardware design, MCU choice, and connectivity stack. If there is a component availability risk or a certification issue, we raise it before the PCB is finalized, not after.
Architecture Planning
We define the firmware architecture, OTA strategy, device identity model, and cloud backend design together. These decisions are significantly harder to change once hardware is in hand.
Firmware and Edge Development
Firmware and cloud backend development run in parallel from sprint one. OTA is not added later. Every major component has a hardware-in-the-loop test before it ships.
Cloud Backend and Dashboards
We build the telemetry ingestion pipeline, device shadow services, and operator dashboards while firmware matures. Integration tests run against real devices on the bench.
Controlled Pilot Deployment
A small-fleet pilot catches the issues that only surface in the field: provisioning edge cases, real network conditions, and the support workflows your team will actually need.
Production Rollout and Handoff
Scaled deployment uses staged OTA rollouts with health gates. Your team receives documentation and runbooks, and the same engineers who built the system are available for post-launch support.
