The full-stack IoT pipeline
End-to-End IoT Engineering
From microcontroller firmware to cloud infrastructure to mobile apps — we own the full stack so you don't have to.
IoT System Development
Full-Stack IoT from Silicon to Screen
We architect and ship complete IoT ecosystems — from bare-metal firmware on ESP32/ESP8266 to cloud-connected dashboards. Every layer designed for real-world reliability.
- ESP32 / ESP8266 firmware (C/C++)
- MQTT, WebSocket, CoAP protocols
- AWS IoT Core & custom brokers
- OTA update infrastructure
- TLS/mTLS end-to-end security
- Sub-100ms real-time control
Embedded Systems Engineering
Hardware complexity → Human simplicity
Low-level firmware that is production-hardened, power-optimised, and secure from the start. Raspberry Pi, Arduino, custom boards — we speak silicon.
- Bare-metal C / C++ firmware
- RTOS integration (FreeRTOS)
- Power optimisation for battery devices
- Hardware-in-the-loop testing
- LoRa / LoRaWAN mesh networks
- TinyML on-device AI
Cross-Platform Mobile Apps
Flutter — One Codebase, Native Performance
Beautiful, high-performance mobile apps with real-time IoT integration. 10,000+ downloads across our deployed apps.

}Principles That Drive Us
Six rules we never compromise on — from the first commit to the 10,000th device.
Reliability First
Design for failure — every node, every link. We model failure modes before the first line of firmware is written.
Zero-Trust Security
TLS/mTLS from day one, not as an afterthought. Your devices and data are encrypted end-to-end at every layer.
Cloud-Native Scalability
Architecture that grows from 10 devices to 10,000 without re-engineering. Kubernetes-ready from the start.
Full Observability
If you can't measure it, you can't improve it. Every deployment ships with monitoring, logging, and alerting.
Human-Centric UX
Hardware complexity translated into human simplicity. Complex telemetry becomes a clean, intuitive interface.
On-Time Delivery
Production-ready. Secure. Scalable. We ship what we commit — with a 99.9% uptime SLA to back it up.
