Web application development

We build web applications that work as tools, not presentations: client panels, dashboards, booking systems, system-to-system integrations and SaaS platforms.

You work directly with the people who write the code and design the product. After the first call you get a concrete quote — scope, timeline and figure, with no hidden line items.

What we build most often

Four kinds of projects that keep coming back to us — each shaped around a real business process.

  • Panels and dashboards

    Managing data, clients and processes in one place, with roles and permissions.

  • System integrations

    We connect CRMs, payments, warehouses, courier APIs and SMS gateways into one coherent flow.

  • Booking and ordering systems

    Availability rules, notifications, online payments — no more juggling calendars by hand.

  • SaaS MVPs

    The smallest version that actually reaches users and validates the idea before you spend the whole budget.

Technology picked for the project

We pick the stack to fit the project (most often TypeScript, Angular, Node), not the other way around. We build in short iterations with regular previews — a working prototype usually lands in 2–4 weeks, a full MVP in 4–8. If an approach makes no sense in your case, we say so plainly.

Everything stays yours

Code, infrastructure, domains and every credential are your property from day one — plus documentation, team handover and post-launch care. And since Polish rates are a fraction of Western European ones for the same seniority, nearshoring here simply adds up.

Process

Four steps. No corporate theatre.

  1. 1

    Conversation

    30–60 minutes to understand goal, constraints and context. We say so plainly if it's not a fit.

  2. 2

    Proposal

    A concrete proposal: scope, timeline, cost. No hidden line items, no 'starting from'.

  3. 3

    Build

    Short iterations, regular previews, one point of contact on our side. No three-week disappearances.

  4. 4

    Launch & support

    Go-live, team handover and post-launch support. We stick around — the product keeps going.

FAQ

Frequently asked questions

How does a web app project start?

With a conversation about the business goal, not the technology. Based on it we propose an MVP scope, a timeline and a concrete figure. Only after you accept do we start building — in short iterations, with previews every week or two.

What is the difference between a prototype and an MVP?

A prototype (€1,200–2,500) is a clickable first version of one core feature — for showing users or investors and validating the idea. An MVP (from €2,800) is a product you can actually run day to day: with login, deployment on production infrastructure and post-launch support.

Will you take over an app built by someone else?

Yes. We start with a code and infrastructure review, after which you get an honest assessment: what can be developed further and what needs rebuilding. We also maintain and develop applications we did not build from scratch.

What do I get besides the code?

A deployed, working application on infrastructure you fully control, documentation, team handover and a period of post-launch care. The code and all access credentials are yours.

Do you work with clients outside Poland?

Yes — we work fully remotely across the EU. The whole process, from the first call through previews to launch, runs online, in English.
