Our products
We design and ship our own software, focused on solving real problems for real customers. Plagiano is the first; more are on the way.
Software architecture, AI integration, and product engineering.
Danielson Ulvstranden AB designs, builds, integrates, and operates business-critical software — as our own products, as a senior consulting partner, and as the team that helps others put modern AI to real use inside the systems they already depend on.
What we do
Three practices, one company.
DUAB operates three reinforcing practices: building our own products, partnering with organisations as senior architects and engineers, and helping teams put modern AI to real use inside the systems they already depend on.
Consulting & architecture
When organisations need senior architectural judgement, we step in. From technical strategy to hands-on engineering, we help teams design and evolve systems that hold up over time.
AI integration
Two threads, both real: we're integrating LLM-powered features directly into bonuscard.com — a loyalty platform serving physical retail and e-commerce — while our day-to-day engineering practice runs on AI-assisted tooling throughout. Clients benefit from both: concrete experience putting AI into business-critical systems, and a delivery practice tuned to use it.
Products
Software we build and operate ourselves.
Plagiano is the first product DUAB has brought to market. We're working on more — but our energy stays on what's in front of us today.
Plagiano
Real-time exam monitoring and plagiarism detection for schools.
Plagiano combines a Chrome extension, a real-time backend, and an optional Windows lockdown service to give teachers verifiable assurance that student work is original. Designed for schools and institutions that need exam integrity without disrupting normal classroom workflow.
Consulting
Senior architecture & engineering, for organisations that depend on their software.
DUAB partners with technical leaders on the decisions that are too important to get wrong: platform direction, system design, integrations, and how to evolve a codebase that already carries a business. We focus on long-term maintainability and clear architectural intent — and we are not afraid to write the code ourselves.

About
The person behind DUAB.
Danielson Ulvstranden AB was founded by Andreas Ulvstranden, a senior software architect with two decades of experience designing and building business-critical systems — most of it written in .NET, much of it powering retail, e-commerce, and integrations at scale.
Andreas combines architectural clarity with hands-on engineering, taking overall technical responsibility, guiding teams, and making pragmatic decisions that stand the test of time. While not being afraid to dig into code himself.
