We work closely with our clients as trusted technology advisors, delivering scalable web platforms, e-commerce ecosystems and custom software products. Alongside client work, we actively invest in our own products and open-source ecosystem. One of our key initiatives is MDCMS --- an open-source, AI-native content engine and Markdown-first CMS designed for modern developer workflows. MDCMS is built around code-first schemas, developer tooling, AI workflows and open infrastructure principles. We see it not only as a product, but as an ecosystem --- one we want to grow together with contributors, developers, creators and the wider OSS community.
