Dev and Deliver

Senior React and Node.js teams from Kraków

Dev and Deliver, a software house in Kraków, Poland, develops web and mobile products in React, Next.js and Node.js. Its engineers are senior, not generalists, and its clients are mostly CTOs and founders in Europe. The process runs from the first workshop through ideation, prototyping, design and development to launch, and the company stays on after release for ongoing support, so a product can keep changing once it is live.

Custom builds, MVPs and legacy modernisation

Custom development covers minimum viable products, complete product builds and the renewal of older systems, including taking over an existing codebase. The firm reports more than 300 projects delivered for startups, mid-sized companies and enterprises. Product and UX/UI design come before development, and quality assurance pairs manual testing with test automation within each build. The team works in Agile methods such as Scrum, which keeps the client close to progress.

Mobile apps built on React Native

For mobile work the company builds iOS and Android apps with React Native and backs them with Node.js services. It reports that products built this way have been downloaded by thousands of end users through Google Play and the App Store. Its engineers can also be placed into a client's own effort, either as a full team with developers, project managers, DevOps, architects, QA and designers, or as a single specialist who fills a gap, for a set duration or on a fixed budget.

Recent work: an AI platform, a booking marketplace and a compliance app

Recent examples include Immersey, which turned a developer tool for game characters into an AI platform, and a Danish booking marketplace taken from idea to live in seven weeks. The firm also added AI-powered non-player characters with memory to BattleRise, a game by Foregamer, and rebuilt the customer app for Hemfrid, a cleaning company. For Speeki the team has grown a single feature into a compliance platform now serving more than 100 enterprise clients, an engagement that has run for more than five years.

Stack and long-term support

The stack is React, Next.js, React Native, Node.js and NestJS, with work on Google Cloud and AWS. The firm says it stays for the long run, not just the launch, and that its senior-only approach is meant to keep products sound for years after release rather than only past launch. Clients who need an extra engineer or a whole team can add capacity to an existing effort without rebuilding the project around new people.
