On our own server or in the cloud?

Either. If the data must not leave the country we deploy on your server; if you need a fast start, in the cloud. The choice follows the sensitivity of the data and the budget.

How many devices can connect?

The design is chosen for the target count from the outset. Hundreds of devices fit on one server; tens of thousands need a broker cluster and a separate database. We establish this at the start of the project.

Can you connect our existing devices?

If the device speaks MQTT, HTTP or Modbus, yes. With devices using a closed protocol the protocol has to be investigated first — that is quoted as a separate job.

Can the dashboard be an off-the-shelf tool?

Yes — in simple cases something like Grafana saves both time and budget. If you need a custom workflow and user roles, the dashboard is built from scratch.

How long is data kept?

You decide. Typically raw data is kept for a few months and aggregated figures for years — that keeps the database size manageable.

Do you accept small prototypes or research projects?

Yes. We accept small proof-of-concept or research projects. Send your project description — I'll provide price and timeline estimate.

Which EDA tool do you use for PCB design?

Primarily KiCad (open-source, commercially usable) and Altium Designer. If the client has a specific requirement, other tools (Eagle, DipTrace) are also possible.

Is firmware limited to STM32 and ESP32 only?

No. STM32 and ESP32 are what we work with most, but Arduino (AVR), Raspberry Pi Pico (RP2040), Nordic nRF, Microchip PIC, Atmel are also possible. We recommend optimal MCU based on project requirements.

Do you sign NDAs (Non-Disclosure Agreements)?

Yes. Frequently required in engineering projects. We work with either a standard NDA template or your company's template.

IoT Platform and Backend Development

IoT platform development — MQTT broker, device management, database and dashboard. Node.js, Python (FastAPI), Mosquitto/EMQX, REST and WebSocket APIs.

Backend, API, cloud integration. Python, Node.js, MQTT brokers, REST/WebSocket, dashboards.

A device may work perfectly, but it is worth little if the data does not flow somewhere. An IoT platform builds that flow: the device publishes, the broker receives, the database stores, the dashboard displays, and an alert goes out when a threshold is crossed.

For transport we use MQTT (Mosquitto or EMQX); the backend is built on Node.js or Python (FastAPI); data is stored in PostgreSQL or a time-series database. Between device and dashboard there are REST and WebSocket APIs — one for queries, the other for live updates.

Scale is settled at the start: a design that works with 10 devices can fall apart at 10,000. Device provisioning, key management, message rate and data retention are defined at the beginning of the project.

03
PCB Layout and Firmware
PCB design (KiCad/Altium), signal integrity, EMC checks. Firmware developed in parallel. Interim reviews.
04
Prototype and Testing
First PCB batch assembled and lab-tested. Validation with firmware. Required adjustments.
05
Production and Support
DFM optimization for mass production. Documentation, user manual, long-term technical support.
