IoT & Embedded

Hardware that thinks.
Software that connects.

We design the silicon, write the firmware, build the cloud backend, and ship the mobile app. One team. Zero integration headaches.

What we build.

End-to-end IoT development — from the first schematic to a fleet of devices in the field.

Custom PCB Design
Schematic capture, layout, DFM review, and prototype spins. We design boards that survive real-world conditions — vibration, temperature extremes, marine environments.
Firmware Development
Bare-metal and RTOS firmware in C/C++ for ESP32, STM32, and custom silicon. Power-optimized, security-hardened, and designed for OTA updates from day one.
Cloud Connectivity
Seamless device-to-cloud pipelines via MQTT, HTTPS, and WebSockets. Azure IoT Hub integration, device provisioning, certificate management, and data routing.
OTA Updates
Deploy firmware to thousands of devices simultaneously. Delta updates, staged rollouts, rollback protection, and audit logs for enterprise compliance.
Industrial IoT
Ruggedized solutions for factories, furnaces, and harsh environments. Modbus, CAN bus, RS-485 integration. Certified for industrial deployments.
Fleet Management
Monitor, configure, and diagnose thousands of deployed devices from a single dashboard. Alerts, geolocation, usage analytics, and remote command execution.

// IoT stack

From sensor
to insight.

Every layer — hardware, firmware, connectivity, cloud — designed and built by the same FSS team. No integration risk.

Real-time telemetry
Sub-second data from edge to cloud via MQTT and WebSockets. LoRa for long-range, BLE for proximity, LTE for mobility.
Hardware security
Secure boot, encrypted flash, TLS 1.3 end-to-end. Mutual authentication with Azure IoT Hub using X.509 certificates.
OTA updates
Push firmware updates to the entire fleet without touching a single device. Delta patches, staged rollouts, instant rollback.
