A software house from Słupsk working with companies across Poland.

We build software for companies in specific industries. Instead of starting with technology, we start with your process, and every stage ends with something that works.

Who is behind VistuCode

VistuCode is the brand of Dev Systems Jakub Dziemidowicz, based in Słupsk, Poland. We design and build websites, web and mobile apps and custom systems for companies that want technology to serve their processes, not the other way round.

We always start with how your company works today: who does what, where information gets lost and what every manual task costs. Only then do we propose a solution and split it into stages, each delivering something you can see and check.

VistuCode is one person: Jakub Dziemidowicz. You talk directly to the person who analyses your process, designs and writes the code, with no salespeople or middlemen. Decisions are quick and nothing gets lost along the way.

We work with clients across Poland and abroad, remotely and on site. We run workshops, acceptance sessions and training wherever your company works.

Why we focus on industries

A generalist software house learns your industry on your budget. We focus on 20 industries where we know the regulations, the systems you need to integrate with and the habits of your customers. So the first workshop starts with specifics, and some modules, such as online booking, a 3D apartment finder or KSeF integration, don’t start from scratch.

How we work day to day

We speak plainly
If something makes no business sense, we say so before the quote, not after launch.
Less, but better
We’d rather ship a first version with five features you use than twenty nobody remembers.
We reply within a day
We answer every message within one business day, after launch too.
We stay after launch
Launch is the start. We monitor, fix and grow the system together with your company.
