Clients we have worked with
Company and approach

First, we understand the business. Then, we design a solution.

Behind every project are people, workflows, and constraints. We work together with your team to understand these elements in order to create software that fits into the company’s operations and helps it grow.

01

Understand the context

How do users operate, where is time lost, and what data is needed for decisions? We consider industry specifics and existing systems.

02

Choose the architecture for the task

We align priorities, integrations, and constraints. We select technologies and define the scope of the first version based on workload, budget, and future development needs.

03

Work with your team

We discuss solutions, demonstrate working scenarios, and clarify next steps. You can see what is being created and how it relates to business goals.

Industry expertise

We understand the complexity behind the interface

Equipment protocols, data flows, business rules and operator actions have to work together. Our industry solutions are built on those connections.

Energy and storage

A unified view of generation, battery status, and equipment operation. Telemetry, diagnostics, and events are placed within the context of operator tasks.

EV charging infrastructure

Platforms for charging network operators: from connecting stations and managing sessions to load distribution and working with partners.

OCPP · OCPI · CPO and EMSP Platforms

Explore this industry

Video infrastructure

Processing, securing, and delivering video streams. We integrate transcoding, hardware acceleration, and infrastructure management into a single process.

End-to-end development

Every part of your product, one coherent architecture

We design the user interface, backend, data and external integrations together. The scope depends on your project: start with a single workflow or develop an entire platform.

Business applications

CRM systems, internal portals, web, and mobile applications with logic, roles, and workflows tailored to your company.

Explore this capability

Integrations and data

Integration of corporate systems, external APIs, and hardware. Data collection and processing for operations, analytics, and management.

Explore this capability

Modernization and infrastructure

Developing existing software, updating architecture, and choosing between cloud or on-premises solutions. Phased transition and system monitoring.

Applied AI

AI where it adds value to your process

We begin with a specific operation and the data it works with. We test the scenario using examples from your team, define quality requirements, and integrate AI into existing software.

More on AI development
  • Searching through corporate knowledge with source references.
  • Extracting and verifying data from documents before submitting it to the business system.
  • Preparing replies and workflow outputs, with uncertain cases passed to a team member.

When designing, we consider data access, processing costs, model deployment, and error handling procedures.

Examples of solutions

Collaboration

From the first conversation to ongoing development

01

Understand the task

We identify users, constraints, and success criteria. We establish priorities for the first phase.

02

Design and validate

We align the architecture and integrations. We test the most uncertain scenarios using a prototype or pilot.

03

Build in stages

We demonstrate working functions, gather feedback, and verify the agreed requirements.

04

Launch and evolve

We plan the transition, monitoring, and handover of the system. We coordinate support and subsequent development stages.

Before starting the project

What is important to discuss

Can we start without a technical specification?

Yes. For the first conversation, it is sufficient to describe the process, current challenges, and desired changes. Together, we will determine what needs clarification, what constraints must be considered, and where to start.

Can you improve our existing systems?

Yes. We start by examining the architecture, data, and integrations. After that, we determine which parts can be retained, what requires changes, and how to organize the transition while considering the business’s current operations.

Do you work outside of the listed industries?

We examine projects with complex business logic, data, and integrations across various fields. During the initial discussion, we clarify the domain, requirements, and whether the task falls within our expertise.

How do you decide whether a project needs AI?

First, we analyze the operation and available data. If using AI is justified, we test it in real scenarios: evaluating result quality, processing costs, and the need for employee oversight.

How are the timeline, cost, and deployment of the system determined?

The evaluation depends on volume, integrations, data quality, and technical constraints. We choose between cloud or on-premises deployment based on access and operational requirements. After clarifying the tasks, we agree on the phases and scope of work.

What happens after launch?

We agree on documentation handover, support arrangements and responsibilities in advance. The scope of support, incident response and further development is defined for each project.
