What microcontrollers do you support?

We specialize in ESP32 (Expressif) and STM32 (STMicroelectronics) chips using FreeRTOS and Arduino runtimes.

How do you ensure data security for IoT?

We bind TLS certificates on the devices, requiring encrypted handshakes for MQTT publish/subscribe commands.

What databases do you use for sensor data?

We use TimescaleDB (Postgres extension) and InfluxDB to process high-volume sensor writes efficiently.

Do you design physical PCB layouts?

We plan wiring diagrams, sensor alignments, and prototype circuits. We partner with specialized fabs for final production-run PCB layouts.

IoT & Smart Systems Engineering

Lightweight firmware engineering, sensor hardware integrations, and secure cloud telemetry streams.

Connecting physical hardware devices to the cloud requires lightweight execution routines and secure data protocols. We write robust firmware for ESP32 and STM32 microcontrollers, establish secure publish/subscribe MQTT telemetry streams, and build time-series database nodes (TimescaleDB) with custom Grafana dashboards for remote device fleet tracking.

Capabilities

What We Provide

Microcontroller Firmware Development

We write clean, structured C/C++ firmware utilizing FreeRTOS for task scheduling on ESP32, STM32, and Arduino chips.

Key Deliverables:

FreeRTOS Firmware Binaries

System Wiring Schematics

Fleet Over-the-Air Update Rules

Secure Telemetry Streams

We design low-overhead MQTT broker clusters (HiveMQ, EMQX) with TLS certificate bindings, enabling secure publish/subscribe messaging.

Key Deliverables:

MQTT Broker Deployment Scripts

TLS Certificate Bindings

Client Ingestion Rate Limits

Time-Series Ingestion & Storage

Avoid database locking under heavy sensor loads. We configure TimescaleDB and InfluxDB clusters to archive telemetry values.
