From idea to working digital product.
We help companies validate, design and build custom applications — from focused POCs and MVPs to secure, production-ready products.

Explore our workYou just use your application. We take care of everything else.
Most agencies hand you off — strategy to design, design to build, build to someone else’s operations team. We do not. The people in the kickoff are the people who write the code and get the pager.

Product Strategy & Discovery
Work out what to build
You have an idea. We turn it into a plan with a price tag — before anyone writes a line of code.
- Workshops
- Scope & priorities
- Technical plan
- Budget estimate
UX/UI & Product Design
Make it beautiful and obvious
Apps and websites people actually enjoy using. Nobody should need a training course to find the right button.
- User research
- Information architecture
- Prototypes
- Design systems
- Fiori design guidelines
POC & MVP Development
Build a small version first
Working software in weeks, not quarters. You click through the real thing before committing to the whole thing.
- Proof of concept
- Shippable MVP
- Production-grade architecture
- Real-user validation
Custom Software Development
Build the real thing
The full application, built to last. Connected to the systems you already run — not another island beside them.
- React & TypeScript
- Java & Spring Boot
- PostgreSQL & SAP HANA
- APIs & integrations
Cloud, DevOps & Secure Hosting
Keep it running, safely
We host it, protect the logins and watch it around the clock. You never have to think about servers.
- Docker & Ansible
- CI/CD pipelines
- OAuth 2.0 & Keycloak
- Role-based access
- GDPR by design
Maintenance, Support & Ongoing Development
Keep making it better
Updates, security patches and new features. We stay your team long after launch — same people, same phone number.
- Monitoring
- Updates & security patches
- Product roadmap
- Direct access to the developers
We do not just build software. We run it.
The fastest way to judge a development partner is to look at the software they keep alive themselves. DIDI is the maritime platform we designed and built inside Decorum Group — running commercially today. Dexi is our AI assistant for enterprise knowledge.
DIDI-MRV
Regulatory CO₂ reporting for shipping. DIDI-MRV consolidates data from logbooks, onboard sensors and handwritten notes into one auditable reporting workflow for EU-MRV, UK-MRV and IMO-DCS.
Emissions data arrives fragmented across shipboard systems, which makes manual, spreadsheet-based reporting slow and error-prone against hard regulatory deadlines. DIDI-MRV replaces that with a single platform: a reactive Java and Spring Boot WebFlux backend, a SAPUI5 and OpenBridge interface built to maritime bridge standards, Keycloak and OAuth 2.0 for access control, and end-to-end tests in Playwright running through GitHub CI/CD.
DIDI-Chart
Automated ENC updates for ECDIS. DIDI-Chart delivers encrypted, verified chart updates across a whole fleet and retires manual USB-stick distribution.
Keeping ECDIS charts current has traditionally meant couriering USB sticks to vessels and trusting that someone aboard applied them correctly — with no shoreside visibility into whether a ship is actually compliant. DIDI-Chart automates the whole path: encrypted, verified ENC delivery over links that may be intermittent or low-bandwidth, every file hash-validated twice, and a shore dashboard showing update and compliance status across the fleet. Vendor-agnostic across major ECDIS systems, supporting UKHO AVCS, AIO, ARCS, PRIMAR and C-MAP.
Dexi
An AI-powered assistant that connects enterprise knowledge across SAP, cloud tools and internal documentation into one search experience.
A policy document, an SAP configuration guide and a project update in Teams normally live in three systems that do not talk to each other. Dexi indexes them together, so people find the answer instead of the folder — making information findable, understandable and actionable.
Three disciplines. No gaps. No handovers.
Decorum Experience GmbH is a senior team, deliberately. Design, frontend, and backend with cloud and security — the three disciplines a digital product actually needs, each owned by a specialist with a decade or more in it.
That means you work directly with the people who build your product. No account managers relaying requirements, no juniors learning on your budget, and no gap between the team that pitched and the team that delivers.
We are part of Decorum Group, alongside Decorum Consulting GmbH and Decorum Maritime. Where a project needs certified data protection expertise or deep SAP authorisation work, we bring in colleagues who do that full time.
Design & UX
User research, information architecture, wireframes through interactive prototypes, design refinement and user acceptance testing. Fiori design guidelines where SAP is involved.
Frontend & UI Engineering
SAP UI5, Fiori and Fiori Elements alongside React and TypeScript. Performance work through lazy loading, caching and efficient rendering. Test automation with QUnit and Playwright.
Backend, Cloud & Security
Java and Spring Boot, microservice architectures, OData and REST APIs, PostgreSQL and SAP HANA. OAuth 2.0, Keycloak and role-based access control. Docker, Ansible and CI/CD through to operations.
Part of Decorum Group. For data protection and SAP authorisation topics we work with Decorum Consulting GmbH, whose certified data protection officer supports our projects.
