Selected Work
Client projects, platforms, and founder-built tools that show how we think, build, and operate.
KLHdesigner
Project in collaboration with Omnity e.U.
KLHdesigner is an all-in-one digital platform designed to support professionals in timber construction with KLH® – CLT. It offers comprehensive tools and resources that streamline the planning, simulation, and sustainability assessment processes for structural engineering, making it an essential solution for architects, engineers, and construction specialists working with engineered timber structures.
SELF
Project in collaboration with Omnity e.U.
Web-based application for assessing, managing, and analyzing behavioral tendencies, communication preferences, and interpersonal and team dynamics through comprehensive questionnaires, including tools for invites, reminders, and reports.
barrieretest.at
Founder project by Solasit e.U.
barrieretest.at checks websites for accessibility against WCAG 2.2. The result marks every finding on the page with a number and shows the page in eight views, such as on a phone or with colour blindness. Each finding explains in plain language who it affects and how to fix it. AI analysis is optional. The core is open source.
Open Source & Research
Some of our work also happens outside classic client projects: as open source, research, or our own tools.
@barrieretest/core
Open Source · CLI · CIThe open-source core behind barrieretest.at: automated single-page audits with axe-core, optional pa11y support, scoring, screenshots, JSON output, CI baseline workflows, and optional semantic AI analysis.
Gizual
TU Graz · Master's theses · Open SourceGizual came out of two Master’s theses at Graz University of Technology: a browser-based open-source tool for visualizing and analyzing Git repositories. For Acurion, it demonstrates technical depth: complex data, interactive visualization, and local execution in the browser.
Acurion is new. Our experience is not.
Acurion brings together experience from long-term product development, self-employed work, and shared research. The company is new, but the work behind it has grown over years.
Omnity e.U. & KLHdesigner
Stefan brings experience from Omnity e.U. and the long-term development of KLHdesigner: technical platforms, infrastructure, deployment, and continuous product evolution.
Solasit e.U. & barrieretest.at
Andreas brings his work from Solasit e.U.: UI/UX, user-centered development, and accessibility. With barrieretest.at, he develops his own tool for structured accessibility checks.
