IoT, PLC & Embedded Systems
Embedded work is where a connected project succeeds or quietly fails. We write firmware for devices that have to run unattended for months — on unreliable power, over patchy cellular links, in environments that are hot, dusty, and vibrating.
What this includes
Embedded firmware
Bare-metal and RTOS firmware for STM32 and ESP32 targets, with a bias toward deterministic behaviour and recoverable failure modes.
Cellular IoT connectivity
LTE module integration (EC200U and similar) over AT commands, with MQTT transport, store-and-forward buffering, and reconnect logic that survives real network conditions.
GPS & telemetry
Fleet and asset tracking built on Teltonika FMB-series and comparable hardware, including custom decoding and back-end ingestion.
Sensor integration
Motor status, tank level, flow and machine data taken from analogue and digital sensors and from PLC registers over Modbus, plus LoRa multi-hop relay for sites where cellular coverage does not reach.
Single-board computers & edge devices
Raspberry Pi, Radxa, and Vicharak Axon boards set up as edge gateways, data loggers, display controllers, and vision nodes — Linux image, GPIO and serial wiring to the equipment, services that come back on their own after a reboot, and remote access for support. The board that is right for the job, not the one with the longest spec sheet.
CCTV & IP camera integration
We read the cameras you already have. Streams pulled from the existing NVR or straight off PoE cameras over RTSP, analysed on site, and surfaced in your own dashboard with alerts to WhatsApp or Telegram — in place of the vendor's app, with no per-camera subscription and no footage leaving your premises.
On-device AI at the edge
Inference run on the board's own NPU rather than in a data centre — counting, detection, and anomaly spotting on an Axon or comparable Rockchip RK3588 device. The video never leaves the site, there is no per-camera cloud bill, and it keeps working when the connection does not.
