Software that fits your business, not the other way around
Enterprise software decisions shape operations for years. When the available platforms don't fit, or when business logic is too specific for generic tools, custom development is the right call. DNA Solutions has built mission-critical applications that organizations depend on daily. We've seen what happens when businesses force their processes into rigid platforms: workarounds multiply, maintenance costs spiral, and teams spend more time fighting the tool than doing their work. Custom development eliminates that friction by building exactly what your operations need, nothing more, nothing less.
From architecture to production
We handle the full development lifecycle: requirements analysis, architecture design, development, testing, deployment, and ongoing maintenance. Our team builds on modern stacks while integrating with whatever legacy systems your business runs on. Every application we deliver includes documentation, training, and knowledge transfer, your team owns the result, the code, the architecture decisions, and the operational knowledge to maintain it independently. We follow agile methodology with iterative delivery: working features every two weeks, tested against real scenarios. You see progress continuously, not after six months of silence.

Questions about custom software development?
Building custom software is a significant investment. Here's what you need to know.
At DNA Solutions, simple applications and integrations typically run 2-4 months. Complex platforms, like the Deloitte-audited billing engine we built processing €300M monthly, took longer but delivered in phased sprints. We scope before we quote: our team assesses your systems hands-on before committing to a timeline. Every project follows iterative delivery with working features every two weeks, so you see progress continuously and we catch misalignments early.
You own everything. Every line of code, every architecture document, every deployment script. At DNA Solutions, we build in your repositories, on your cloud accounts, using your CI/CD pipelines from day one. We include structured knowledge transfer sessions so your team can maintain and extend the application independently. That's our philosophy: we build autonomy, not dependency. Our longest client relationships, T-Systems, Satellic, keep coming back by choice, not because they're locked in.
Absolutely. DNA Solutions was built on enterprise stacks that most development shops avoid. We've written middleware for Oracle Billing, built API layers on top of SAP, connected AFAS with modern platforms, and integrated decades-old COBOL systems with microservices architectures. Our 38+ engineers bring deep experience across Oracle, SAP, .NET, Java, and cloud-native stacks, it's why organizations like the European Commission trust us with their critical infrastructure.
We follow agile methodology with iterative delivery, it's how DNA Solutions has delivered every project for the past decade. Changes aren't disruptions; they're expected. Each sprint delivers working features you can test, and we reprioritize the backlog together based on real feedback. Scope changes are managed transparently: we assess impact, adjust the timeline if needed, and communicate clearly. The Satellic billing platform we maintain has evolved continuously over 6+ years, proof that our process handles change at scale.
