How we work

How we can help

Step 01

Concept & analysis

Together we define the requirements, product architecture and technical goals — from electronics to software.

Step 02

Development & prototype

We design the circuit, develop the firmware and backend systems, and deliver a working prototype.

Step 03

Production & support

We prepare the product for production and handle over-the-air (OTA) updates, integrations and maintenance.

Our services

The full stack — from electronics to AI

We cover every layer of the product: hardware, embedded firmware, connectivity, cloud and artificial intelligence.

Embedded systems & firmware

Reliable embedded firmware for microcontrollers — low power, real-time systems and remote updates.

STM32, ESP32, ATSAM
FreeRTOS, interrupt-driven, DMA
OTA updates and bootloaders

Electronics & PCB design

Printed circuit board design from idea to production — analog, digital and mixed-signal.

Altium Designer, multi-layer boards
Power supplies (AC-DC, buck, LDO)
Sensors and analog front-ends

Industrial automation

Integration and automation of industrial and laboratory equipment with measurement-grade accuracy.

OPC UA, SCPI, RS-485 / Modbus
Measurement and dosing systems
Test automation and calibration

IoT products (full stack)

The complete IoT stack from one partner: from the sensor on the board to the cloud dashboard.

PCB → firmware → cloud
LoRa / LTE / BLE / MQTT
Dashboards and mobile apps

Backend, cloud & DevOps

Powerful backend services and infrastructure — secure, scalable and automated.

PHP, Python, FastAPI, REST API
Docker, Nginx, Linux servers
MySQL / MariaDB, SQLite

AI & LLM integration

Practical AI integration — knowledge retrieval and automation with local models.

RAG systems and vector databases
Ollama and local LLMs
Question answering over documents (PDF)

Why DEVX

We don't just write functions — we build whole products

The full stack from one partner

From schematic and PCB to firmware, cloud backend and dashboard — all under one roof, with no coordination between vendors.

A systems approach

We think in products, not isolated components. The starting question is always "How do we build the complete product?", not just "How do we write this function?".
