What we do

Software used to be slow, expensive and risky. We work with senior engineers and the best AI tools side by side, so ideas reach production faster, with code you can read, test and own.

01Services

Everything software, under one roof.

Twelve service lines that fit together. Start with one, or hand us the whole product from the first sketch to the on-call rota.

02AI-native delivery

Senior engineers. Agentic tools. One standard of quality.

We build with Claude Code and other agentic tools every day. They write, test and refactor code under the direction of senior engineers who own the architecture and review every change. You get the speed of AI and the accountability of a team.

  1. 01

    Faster from brief to build

    Prototypes, scaffolding and tests are generated in hours, so workshops end with working software instead of slides.

  2. 02

    Reviewed by people

    Nothing merges without a human review, automated tests and security checks.

  3. 03

    More done per sprint

    Routine work is automated, so the team spends its time on the hard problems.

  4. 04

    Readable code you own

    Conventional, documented code in your repository. No black boxes, no lock-in.

import Anthropic from "@anthropic-ai/sdk";
import { tools, runTools } from "./erp-tools";

const client = new Anthropic();

export async function resolve(ticket: Ticket) {
  const messages: Anthropic.MessageParam[] = [
    { role: "user", content: ticket.body },
  ];
  while (true) {
    const res = await client.messages.create({
      model: "claude-opus-5-5",
      max_tokens: 2048,
      system: "Resolve order issues. Use the ERP tools.",
      tools,
      messages,
    });
    if (res.stop_reason !== "tool_use") return res;
    messages.push({ role: "assistant", content: res.content });
    messages.push({ role: "user", content: await runTools(res.content) });
  }
}

03Technology

A stack as wide as your ambition.

We are not married to one framework. We pick the tool that fits your product, your team and your budget, and we know each of these well.

04Approach

A process built for speed and certainty.

Six steps, the same for a prototype and for a platform. You always know what is happening, what it costs and what comes next.

  1. 01

    Discover

    Workshops with your team, users and data. We define goals, risks and what success looks like.

    Outcome: Product brief, scope, estimate

  2. 02

    Design

    Flows, interfaces and a clickable prototype tested with real users.

    Outcome: Prototype, design system

  3. 03

    Architect

    Technology choices, data model, integrations and security, written down and agreed.

    Outcome: Architecture decision records

  4. 04

    Build

    Weekly releases to a preview environment. AI-assisted development, human-reviewed code.

    Outcome: Working software every week

  5. 05

    Launch

    Load tests, security review, monitoring and a rollout plan without surprises.

    Outcome: Production release, runbooks

  6. 06

    Grow

    Analytics, experiments and a care plan that keeps the product fast, safe and evolving.

    Outcome: Roadmap, SLA, reports

07FAQ

Questions we hear most.

What does em27code do?

em27code is a full-service software house. We design, build and maintain web applications, mobile apps, AI solutions, SaaS products, e-commerce, cloud infrastructure, data platforms and integrations.

What does AI-native mean for my project?

Our engineers use agentic tools such as Claude Code to write, test and document code faster. Senior engineers set the architecture and review every change, so speed never comes at the cost of quality.

How much does a project cost?

It depends on scope, integrations and timeline. After a short discovery call we send a range with the assumptions behind it. Tell us about your project and we will reply within one business day.

Do you work with clients outside Poland?

Yes. We work remotely across Europe and beyond, in English, Polish, French, German and Italian.

Who owns the code and intellectual property?

You do. Repositories, infrastructure and IP belong to you from the start.

Can you take over an existing project?

Yes. We begin with an audit of code, infrastructure and security, then propose a plan to stabilise and continue development.
