FarmTrack
Field sensor network and embedded data acquisition giving a farm real-time operational visibility — previously reliant on end-of-day paper records.
Embedded & IoT Engineering
Reliable firmware and embedded systems for products that must work every time.
For business leaders
Hardware does not tolerate bugs the way software can.
Embedded systems failures are expensive: product recalls, field returns, customer safety incidents, and reputational damage. TNS Growth builds embedded software with production reliability as the starting constraint — not an afterthought. We have shipped firmware, run production embedded Linux, implemented RTOS solutions, and built IoT systems across multiple hardware platforms.

Technical depth
Production-grade firmware across multiple embedded platforms.
We work across the embedded stack — from hardware bring-up and device driver development through application-layer firmware and IoT connectivity. We write embedded C and C++ with the rigor that production hardware demands: memory safety, deterministic timing, tested failure paths.

Who this is for
Common situations where we can help.
You are developing a hardware product and need embedded firmware
We join your hardware development process to design and build the firmware stack — from bring-up through production-ready firmware with full documentation.
Your existing firmware has reliability issues in the field
We audit your codebase, identify the root causes of field failures, and implement the fixes and safeguards needed to restore production reliability.
You need IoT connectivity and OTA updates for your device
We design and implement a secure IoT connectivity stack with OTA update capability — so you can push firmware updates to devices in the field without physical access.
