What We Do

One senior crew, the whole stack — design, build, ship, and grow.

01

Mobile Apps

Native iOS & Android plus cross-platform builds with React Native and Flutter — fast, fluid, built to scale.

02

Web Applications

Dashboards, SaaS platforms, and progressive web apps using React, Next.js, and Node — built for real load.

03

Product & UX Design

Research, prototypes, and design systems. Interfaces that feel obvious and look unmistakably yours.

04

Cloud & Backend

APIs, microservices, and real-time infrastructure on AWS, GCP, and Azure — reliable and observable.

05

AI Integration

Assistants, automation, and recommendations powered by modern LLMs and custom models.

06

DevOps & Support

CI/CD pipelines, monitoring, and post-launch iteration driven by what your users actually do.

How It Works

Four passes through the press. Zero guesswork.

1

Discover

We map your business, users, and goals — then scope requirements and risks before any code is written.

2

Design

Wireframes become clickable prototypes. We validate ideas early, while changes are still cheap.

3

Build

Two-week sprints, live demos, clean code, and automated testing at every checkpoint.

4

Ship

Store submission, production deploy, analytics — then we iterate based on real data.

№ 04

The Toolkit

Chosen for the long run — performance, reliability, a codebase you can own.

EFFORTLESS

We don't just write code — we sweat the details users never have to notice.

Rzymek is a product-minded software studio based in Nowa Chełmża, Poland. We partner with founders and established companies to build apps that move the needle — not just check a box.
