A senior product studio that builds mobile & web apps loud, clean, and on time — from the first sketch to a live store listing.
One senior crew, the whole stack — design, build, ship, and grow.
Native iOS & Android plus cross-platform builds with React Native and Flutter — fast, fluid, built to scale.
Dashboards, SaaS platforms, and progressive web apps using React, Next.js, and Node — built for real load.
Research, prototypes, and design systems. Interfaces that feel obvious and look unmistakably yours.
APIs, microservices, and real-time infrastructure on AWS, GCP, and Azure — reliable and observable.
Assistants, automation, and recommendations powered by modern LLMs and custom models.
CI/CD pipelines, monitoring, and post-launch iteration driven by what your users actually do.
A few things we printed into production.
End-to-end telemedicine & patient management app with real-time booking and EHR integration. 50k+ users across iOS and Android.
Real-time analytics platform with custom charting and live data feeds.
Cross-platform shopping app with AR try-on and AI recommendations.
Four passes through the press. Zero guesswork.
We map your business, users, and goals — then scope requirements and risks before any code is written.
Wireframes become clickable prototypes. We validate ideas early, while changes are still cheap.
Two-week sprints, live demos, clean code, and automated testing at every checkpoint.
Store submission, production deploy, analytics — then we iterate based on real data.
Chosen for the long run — performance, reliability, a codebase you can own.
A small crew that cares about craft.
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.
Senior engineers on every project. Transparent weekly demos. Clean, documented code your team can take over anytime. A real partnership that lasts beyond launch day.
"They shipped two weeks early and the polish was extraordinary. Our users noticed the quality immediately."
"Like having a co-founder who happened to be a brilliant engineer. They pushed us — for the better."
"The backend they built handles millions of events a second without flinching. Exceptional depth."
