Who We Are
A senior engineering team in Zagreb, building production software for clients across Europe.

A bit about us
Resser Solutions d.o.o. is a Croatian software studio focused on end-to-end engineering. We build native mobile apps in Swift and Kotlin, backend systems in .NET and C#, and modern web frontends in Angular and Blazor. The team prioritizes clean code, observability, and long-term maintainability over short-term shortcuts.
We are based in Zagreb and work as a reliable delivery partner for agencies and product teams across Europe. We integrate directly into your workflow, whether as a whitelabel development team or as a trusted outsourcing partner, and we handle the technical heavy lifting from architecture decisions to production deployments.
Our developers have shipped systems for healthcare, construction, hospitality, and logistics clients. We work with transparent communication, agile methodologies, and the understanding that the second version of the code is usually the one we want to ship, not the first.

Extraordinary Experiences
Our individual differences strengthen our teams, and the trust and respect we have for each other infuses passion into everything we do. Someone who is sincerely open considers alternatives, looks at things through a different lens. Opening minds and combining different backgrounds, experiences, world views and expertise makes us savvier problem solvers and drives better results.
We believe that great software is built by great teams. That's why we invest in continuous learning, knowledge sharing, and creating an environment where creativity thrives. Every project is an opportunity to grow, innovate, and deliver something exceptional.
From brainstorming sessions to final deployments, we embrace collaboration at every stage. Our cross-functional approach ensures that design, development, and quality assurance work in harmony to deliver solutions that truly make a difference.

Our Core Values
Helpful: If you know the best way to do something, you'll do good work. If you share that knowledge with others, you'll become a leader. Hungry: We want you to find your comfort zone. And then seek to challenge the hell out of it, over and over. Complacency kills.
Happy: It's nice to be around happy, motivated, and positive people. It's good for you, for the team, and for our customers. We look for this. Humble: While there's always a time and place to celebrate individual accomplishments, no single person is bigger than the team.
These values guide every decision we make, from how we approach technical challenges to how we communicate with clients and teammates. They are the foundation of our culture and the standard we hold ourselves to every single day.

The company in numbers
Facts rather than adjectives, so you can judge whether we are the right size for what you need.
- Founded in 2018 in Zagreb, working under EU law.
- Every engineer on a project is senior. There is no junior layer learning on a client invoice.
- Product teams run two to eight people, sized to the scope rather than to the invoice.
- Four of our eight reference products are ones we co-own, so we carry product risk and not only delivery risk.
- Products in production across five countries, with the longest partnership running continuously since 2019.
- More than ten projects delivered white-label behind a partner brand, roughly a fifth of our work.
- Two engagements have kept the same core team for more than five years.
Where we fit, and where we do not
We sell engineering outcomes rather than seats, which places us between staffing suppliers and full-service consultancies.
A staffing supplier sends you capacity and leaves the delivery risk with you. A full-service consultancy bundles strategy, design and programme leadership, with the commercial weight that comes with it. We take architecture, engineering, QA and production for an agreed scope, and we keep evolving it after launch.
Which means we are the wrong choice in two situations, and it is cheaper to hear that now. If you need thirty developers next month, we cannot do it and will not pretend otherwise. And if you want people to manage yourself day to day, a staffing supplier will serve you better and cost less.
