Stably and safely

Practice from B2B projects and large environments.

Business → decision → implementation

I only recommend what makes sense and return.

One point of contact on the Digital Vantage side

simple communication, predictable implementation.

01

Website and e-commerce that generate inquiries

I design and improve websites that don't just look, but realistically work for sales. We focus on the message, UX, content and technicalities to increase the number of contacts.

⇲
02

Automate and streamline work

I organize tools and processes, integrate systems, and automate repetitive tasks. The result: less manual work, fewer errors and more time for key activities.

⇲
03

Application, MVP, when Excel is no longer enough

I help put together the idea, priorities and scope, and then prove a working product. We build in stages, with a clear plan and cost control.

⇲
04

IT and security that gives you peace of mind

Constant care, auditing, orderly infrastructure and a development plan - so that technology is not a risk, but a foundation. I react quickly and say straight out what is critical and what can wait.

Meet Digital Vantage

My name is Konrad Barejko. I help business owners make sensible technology decisions - ones that really support sales and operations, not stay on slides.
We start with a conversation where we separate the "cool ideas" from the things that will actually deliver a result. After the conversation, you get a clear plan - what we're doing, where the risks are and how much it costs.

Own servers in Poland

Infrastructure on servers in Poland and the EU - full control over data, no vendor lock-in in the cloud.

Milestone billing - you pay for results

Clear milestones, clear billing. Payment tied to specific deliverables, not hours on the clock.

Next.js + Payload CMS

Modern stack: speed, security and scalability. Headless CMS, SSG/SSR, API-first - no legacy ballast.

Collaboration

Your path to a finished project

Action plan and estimation

IT support for companies - Stable operation of tools and work environment: less downtime, faster response to problems and tidier technology.

Security you can trust

Data, stability and compliance are "bundled" with us- You focus on business, we keep an eye on the rest.

FAQ

The most common questions before the first interview

The cost depends on the scope, priorities and whether we start with cleaning up current solutions or implementing from scratch. After a brief conversation, we prepare a recommendation and scope options (from "minimum sense" to a target version) along with an approximate estimate.

No - and it's often better not to have it to begin with. If you have an idea, we start by sorting out the goal, the user and the priorities, and then we verify the assumptions, so that we don't build something that "on paper" looks good, but in practice doesn't work.
In the end, you get a concrete plan: the scope of the MVP / milestones, requirements, risks, estimation and recommendation of what makes sense to do now and what to postpone.

You have a single point of contact on the Digital Vantage side, and we select specialists for the scope of implementation (e.g. architecture, development, UX/UI, graphics, support). This keeps communication simple and implementation predictable.

Most often we start with a conversation at the earliest possible date. We plan the next steps in stages - so that we can quickly deliver the first results and in parallel maintain control over the scope and budget.

Both. We can start with one specific problem (e.g., site improvement, tool integration, automation), and if the collaboration makes sense - develop it further.

Clear direction: what to do first, what to do later, what are the risks and which option makes business sense. If the topic is on our side, we suggest next steps and an indicative estimate.

It is possible to work together on a project basis (in stages) or on an ongoing basis for care and development. The choice of model depends on whether you need a one-time implementation or continuous technological support.

Together we can build something meaningful!
