Our work

Mobile app for homeowners to control their heat pumps

Project duration

Beginning of 2022 — present


Native Mobile apps: Swift for iOS and Kotlin for Android. REST APIs, Websocket, JSON-RPC 2.0 protocol, SSDP and mDNS protocol

Client challenge/business need

Homeowners expect to monitor and control their heat pumps remotely over a mobile app.

The goal is to provide end users extended functionality and insight through the mobile app, in addition to what the device already offers.

Solution at a glance

We created a modern mobile app that enables end users to access and modify their heat pump settings via the cloud.

  • Native apps on iOS and Android control heat pumps in a variety of locations via cloud.
  • User can remotely change their home heating temperatures and other functionalities, including time-based configurations.
  • SSDP and mDNS protocols find the heating devices from the home network, registering these to the cloud.
  • The app communicates with devices over the internet.
  • All updates and changes made in the device appear immediately in the app, which uses the websocket for cloud-side communication.
  • Reusable code library for future product development.


  • Expanded functionalities of heat pump hardware that were not possible by just using hardware; the home climate is managed remotely from anywhere.
  • Home-owners can manage different heat-pumps and other HVAC devices around multiple locations through the same app.
  • Considering the customer’s need to add new devices and smart services in the future, the app architecture is structured in such a way that adding support for new devices to the app is a fast and straightforward process for app developers.

Cloud migration and development for remote devices

Project duration

9800 man-hours; 2+ years


MS Azure, C#, .NET core, MS SQL, Azure Kubernetes, Docker

Client challenge/business need

To make it possible to remotely manage and monitor all the client’s premium devices. The client needed the cloud solution to be stable and cost-efficiently scalable.

Solution at a glance

We built a central device and user data management system that integrates devices and applications on Microsoft® Azure Cloud.


  • The online service our client provides is highly available, reliable and, most importantly, cost-efficient, thanks to the modular system architecture.
  • A central device and user data management system that interacts with devices and mobile and web applications (efficient to manage)
  • Thanks to Azure cloud service the client can outsource the system monitoring and maintenance service.

Cloud migration and CX modernization for a global partner


Multi-part single application, MS Azure, C#, .NET Core, EF Core, MS SQL, Kubernetes, Docker, React JS, Scalable device cloud platform

Client challenge/business need

Improve and optimize the control and monitoring of remote ground-source heat pumps.

Solution at a glance

We improved the software architecture (migration of the solution to the cloud) and brought the system’s end-user experience to the next level.


  • Thanks to online operational data available, heat pump installers can support homeowners’ heat pumps more easily and at a lower cost.
  • Our client’s support call center load decreased significantly. A major part of complaint calls and emails ended immediately after improvements went live.
  • Our client is now focused on building new products, instead of servicing the existing system – all at a much lower cost.

Secure IoT-cloud platform for 3D printing service


MS Azure, .NET, MVC, C#, Bootstrap 3, AngularJS, Toastr, jQuery

Client challenge/business need

To develop a new service platform where 3D-object designers can securely order 3D printing services from print shops for their valuable intellectual property. The client needed the cloud solution to be stable and cost-efficiently scalable.

Solution at a glance

We built a central platform on Microsoft® Azure Cloud that hosts designers’ files, virtual print shops, and integrates 3D printers.


  • The secure cloud service prevented unauthorized access to uploaded intellectual property.
  • 3D print shop managers can connect their 3D printers to the cloud service and manage their virtual workshop remotely.
  • Both 3D-design owners and printer operators can observe the printing process remotely.

Support and maintenance for Enics electronics assembly factories

Project duration

31,000 man-hours, 6+ years


C#, .NET, SAP Manufacturing Execution (ME)

Client challenge/business need

Since 2016, Proekspert has, step by step, streamlined the electronics assembly company’s 24/7 working production tracking system and operator workflows into a stable, reconfigurable, and globally scalable IT infrastructure.

Solution at a glance


  • 24/7 working solution ensured
    We deliver system improvements gradually in a way that system updates never interfere with the work of assembly lines.
  • Scalable to group assembly factories in different regions
    The traceability system was gradually improved in a way that proved universal enough to implement in other Enics factories, as well.
