Annual savings across European clients
Software licensing savings of up to €1M per year for some of our clients.
We connect the ERP, financial and operational systems you already run, centralize access to them with Keycloak, and build custom applications around how your teams work. One team covers all three.
Trusted by Europe's leading organizations
Integration and custom development carry the least glamour and the most operational risk. DNA Solutions treats them as first-class engineering: production-grade middleware, reviewed access control, and applications designed around how your teams actually work.

We connect ERP, financial and operational systems already running in production. Automated ETL pipelines and event-driven architectures move the data between them without manual exports.

We secure enterprise infrastructure with centralized identity management and single sign-on. Our Keycloak architectures govern access across your applications and user directories.

Off-the-shelf software forces your processes into someone else's workflow. We build custom enterprise applications, platforms, and system integrations designed around the way your teams actually work.
Explore serviceIntegration, identity and custom development rarely live apart: DNA Solutions designs the three layers as one architecture, with the same engineers from day one.
We treat middleware as a product with a long life: retry policies, dead-letter queues, daily line-by-line reconciliation and monitoring that flags issues before users do.
Same discipline across the pillar. Identity centralized in Keycloak, access decisions in one reviewed place. Custom software designed around real workflows.
The systems we connect are live, so new pipelines run in parallel until reconciliation proves a match.

We design technology that lands on your bottom line. European enterprises trust us with extreme data volumes and critical financial pipelines.

Software licensing savings of up to €1M per year for some of our clients.
We built and maintain a Deloitte-audited billing platform processing €300M in audited transactions every month.
Several clients have worked with DNA Solutions for six years. We continue to develop and support their software as their needs evolve.
Connections and platforms running daily for European operators.
Most integration landscapes come down to a handful of recurring problems. These are the ones we have already solved for European operators, each running in production today. If your situation maps onto one of them, a large part of the design work is already proven; if it does not, the same engineering approach applies.
Discuss Your LandscapeWe connect ERP and business applications through an integration layer. Data validation, format translation and traceable exception handling support consistent records and reduce manual transfers. Failed records can be reviewed and corrected without replaying the whole exchange, while clear ownership and monitoring help teams maintain the connection over time.
Connecting Oracle databases and applications to the financial and operational platforms around them, so an aging Oracle estate keeps serving the business while the rest of the stack moves forward.
Integrating payment service providers and gateways with billing and back-office systems, with the retry logic and reconciliation needed when every dropped message is money.
Many enterprises run an ERP built in-house years ago. We connect these custom systems to modern platforms without forcing a rewrite, preserving the logic the business depends on.
Designing and building clean APIs in front of systems that never had one, so newer applications, partners, and mobile clients can consume data without touching the platform underneath.
Message-based architectures such as Kafka that move data between systems in real time, with queues that absorb downtime on either side so a temporary outage never turns into lost records.

The answers we give most often when a team first walks us through its system landscape.
We start by mapping the landscape as it actually runs: which systems hold which data, where records are copied by hand, and which platform is the real source of truth for each flow. That map usually surfaces two or three connections causing most of the daily friction, and that is where we begin. The first integration runs in parallel with the existing manual process until reconciliation shows both produce the same records, then the manual step is retired. From there we extend connection by connection, in order of operational pain. You never sign up for a multi-year program on day one; each phase delivers a working connection your team uses before the next one starts.
You do. Everything we build, middleware, custom applications, Keycloak configurations, pipelines, is delivered with full ownership transferred to you. The code lives in repositories you control, the documentation describes how each connection works and how to operate it, and the runbooks cover the failure scenarios. There is no proprietary platform of ours sitting in the middle of your stack and no license fee attached to what we build. If you later decide to hand operations to your internal team or to another vendor, the handover material is already written, because we produce it as part of the delivery rather than as an afterthought.
A single well-scoped integration, one system connected to another with reconciliation and monitoring in place, typically goes to production in eight to twelve weeks. A centralized identity rollout with Keycloak runs on a similar scale, depending on how many applications need to be connected to it. Custom application development is more variable: a first usable version is usually live within a few months, then grows release by release with the teams using it. Larger landscapes are phased, so the calendar is really a sequence of these shorter deliveries rather than one long project. We give a concrete estimate after the mapping work, when we know what each connection involves.
We can maintain integrations after delivery or hand operations to your team with documentation and runbooks. Monitoring and recovery procedures are part of the implementation.
That combination is the reason this service line exists. The three disciplines depend on each other constantly: a custom application needs the integration layer to feed it data and the identity layer to decide who sees what. When three vendors each own one piece, every design decision becomes a coordination meeting and every incident becomes a debate about whose side the problem is on. Our engineers work across all three, so the access model is designed together with the data flows, and the application is built against integrations we know in detail because we wrote them. For you it means one accountable team and one explanation when something needs to change.
