Web Development. Production Web Apps Serving 300,000+ Users.
We build custom web applications for regulated industries. React, Angular, Node.js, .NET Core, AWS. The same teams that built Signal Iduna's insurance platform (300,000+ policyholders), Trusted Carrier's logistics ecosystem (40,000+ docs/week across 22 languages), and Reperks' AI agent interface.

What we build
Front-end development
Interactive, responsive interfaces built with React, Angular, and modern JavaScript. Signal Iduna's policyholder portal, Reperks' conversational AI interface, and Autoklass's e-commerce platform all run on front-end architectures we built. Our UI/UX design team works in the same sprints as engineering. For businesses that need a lower-code option, we also work with Webflow.Back-end development
Server-side systems built with Node.js, Express, and .NET Core. PostgreSQL, MySQL, and MongoDB. Our back-end architectures handle high traffic, complex data processing, and strict security requirements. Trusted Carrier's platform processes 40,000+ documents weekly across 13 countries on infrastructure we built.Full-stack development
Front-end and back-end from a single team. Faster delivery, fewer handoffs, unified architecture. Our full-stack teams work across Node.js, Express, React, Angular, and supporting infrastructure.Web applications with embedded AI
Modern web apps don't just display data. They act on it. We build web applications with AI agents embedded directly into the interface. ZURI runs as a web chat widget qualifying luxury real estate buyers for Vela Zanzibar, handling 400+ daily conversations. Reperks' React-based AI interface processes utility billing documents end to end. Vera, our insurance automation platform, is entirely web-based, covering sales, support, claims, and payments across 9+ insurance lines. DocuFlow delivers intelligent document processing through a browser. All built on our HyperCore agentic framework.Custom websites
Websites tailored to your brand and business goals. WordPress, Strapi, and Webflow depending on your content management needs, performance requirements, and team capabilities. Autoklass’s custom e-commerce platform drove 1 million organic views and 40,000 monthly engagements.APIs and integrations
APIs that connect your web application to payment gateways, CRMs, ERPs, and third-party services. Our Trusted Carrier engagement integrates with BASF and Henkel ERP systems. Our Hamilton Perkins chatbot integrates with e-commerce platforms and inventory systems. We build APIs that work reliably at scale.
