About the technology

Connected systems

The Internet of Things, commonly called IoT, links physical devices to software that collects, exchanges and acts on data. It can support connected products, industrial equipment, smart buildings, fleet operations, medical devices and energy systems. A complete solution usually spans hardware, connectivity, edge processing, cloud services and user applications.

IoT architecture

Strong IoT architecture separates device responsibilities from cloud and application logic. Experts define telemetry models, message flows, device identities, command handling, offline behavior and data retention. They also plan for intermittent networks, firmware changes, regional deployments and safe recovery when devices or services fail.

  • Device and gateway communication
  • Edge processing and event routing
  • Cloud ingestion and storage
  • Monitoring, alerts and operational dashboards

Ecosystem and tooling

IoT projects may use MQTT, CoAP, OPC UA, Modbus, Bluetooth Low Energy, LoRaWAN, cellular networks or Wi-Fi. Common cloud ecosystems include AWS IoT, Azure IoT and Google Cloud services, while embedded work may involve Linux, Zephyr, FreeRTOS and vendor SDKs. The right stack depends on device limits, connectivity, security needs and the required operating model.

When expertise matters

Companies bring in freelance IoT specialists when a proof of concept must become a dependable product, when device fleets need better visibility, or when data from machines is not reaching business systems reliably. Expertise is also valuable during platform migration, hardware integration, security reviews and production rollouts.

  • Connecting legacy equipment to modern services
  • Designing fleet provisioning and device management
  • Reducing unreliable telemetry and duplicate data
  • Preparing pilots for field deployment

Delivery and security

Reliable IoT delivery requires more than connecting a sensor. Professionals work across embedded software, networking, cloud infrastructure, APIs, data engineering and observability. They establish secure boot, certificate management, encrypted transport, least-privilege access, signed updates and clear ownership of device and platform operations.

Choosing a specialist

Look for a professional who can explain trade-offs between edge and cloud processing, select protocols for the actual environment, and show how devices will be diagnosed after deployment. Relevant experience should match the physical setting, connectivity constraints and compliance expectations. Strong specialists document interfaces, automate testing and make field support practical for the teams who will operate the system.

Frequently asked questions

Everything clients usually want to know about Internet of Things, in one place.

The Internet of Things connects physical devices to software so they can collect data, communicate and trigger actions. Companies use IoT for equipment monitoring, predictive maintenance, asset tracking, smart buildings, connected products and industrial automation.

IoT usually adds network connectivity, remote visibility and cloud or edge data processing to physical operations. Traditional automation may control a local process effectively, while IoT can connect information from many sites and integrate it with business systems.

Internet of Things work often requires knowledge of embedded software, networking, cloud infrastructure, cybersecurity and data engineering. Depending on the project, experience with electronics, industrial protocols, mobile applications or API design may also be important.

IoT projects need experience that matches their physical and operational risk rather than a generic technology checklist. A prototype may need strong device and cloud fundamentals, while a production fleet calls for proven provisioning, observability, security, firmware update and incident-response practices.

Internet of Things specialists can handle architecture, firmware reviews, cloud services, testing and documentation remotely when hardware and secure environments are accessible. On-site work may still be useful for installing gateways, testing radio coverage, connecting industrial equipment or investigating field behavior.

IoT solutions commonly use MQTT for lightweight messaging, CoAP for constrained devices, and OPC UA or Modbus in industrial environments. Bluetooth Low Energy, Wi-Fi, LoRaWAN and cellular connectivity may be selected according to range, power use, bandwidth and site conditions.

Internet of Things quality is visible in clear architecture decisions, realistic failure handling and practical security controls. Ask how the specialist handles device identity, intermittent connectivity, observability, updates, data ownership and support after deployment.

IoT professionals should clarify the devices involved, connectivity conditions, deployment environment, ownership of firmware and cloud accounts, and the expected production responsibilities. They should also understand whether the work covers a prototype, a pilot or an operating fleet, because each stage requires different testing and support.

The average hourly rate of freelancers who have used Internet of Things in their recent projects is 106 €, which corresponds to a daily rate of about 844 € based on an 8-hour working day.

Of the freelancers who have used Internet of Things in their recent projects, 93% hold at least a Bachelor's degree, 63% hold at least a Master's degree, and 10% hold a doctorate.

On average, freelancers who have used Internet of Things in their recent projects have 20 years of professional experience, with a single engagement typically lasting around 3.2 years.

The most common languages among freelancers who have used Internet of Things in their recent projects are German (98%), English (97%), and French (21%).

The most common industries among freelancers who have used Internet of Things in their recent projects are Information Technology (89%), Manufacturing (62%), and Automotive (47%).

The most common business areas among freelancers who have used Internet of Things in their recent projects are Information Technology (93%), Product Development (85%), and Project Management (68%).
