Opus – MedusaJS development expert

MedusaJS is an open-source headless e-commerce platform built on Node.js and TypeScript. Because our team works with Node.js, NestJS and React solutions every day, we know the MedusaJS technology inside out and can tailor the platform precisely to your business needs.

Before creating any online store, we work together with the client to map out goals and carry out preliminary work. We then design the store so that the customer journey is simple, inspiring and convenient. Once every detail is in place, our experienced team gets to work on development, ensuring that the final product is high-quality, durable and meets the expectations of both you and your customers.

MedusaJS – a platform that offers everything

MedusaJS is built for modern e-commerce: it supports multiple stores, currencies and languages, different sales channels, B2B price lists and complex order and inventory processes. Because the platform is open source, you pay no licence fee and are not tied to a single vendor.

A headless architecture means that the store’s frontend and backend are separate. This lets you change the store’s design, content management or ERP later without rebuilding the entire store – and the same backend serves your website, mobile app and point-of-sale system at once.

Accessibility (WCAG)
We ensure that digital solutions are in line with the client’s requirements and comply with WCAG (Web Content Accessibility Guidelines) standards. This means that the final solution is accessible to users with diverse needs.
Security (OWASP)
We adhere to the principles of the OWASP security standards to ensure the security of the software. By following OWASP guidelines, we are always aware of the major security vulnerabilities associated with using web applications.
Web hosting
We work with both cloud-based (cloud hosting) and dedicated server-based (dedicated hosting) solutions. We can be your partner in providing exactly the web hosting solution that your business requires.

E-commerce integrations

Content management (CMS)

We connect the store to a content management system, so marketing can manage campaigns, banners and pages without a developer.

Akeneo

Akeneo PIM handles product information only. We set it up by product family and connect it to the ERP and the online store.

AI search

AI-based product search understands the shopper's question, not just keywords, and finds the right product without its exact name.

Warehouse management system

We connect the online store to the warehouse management system, so stock levels, picking and delivery move between the systems automatically.

Maintenance and support: as a long-term partner, we ensure your online store’s continuity

Maintenance and support help ensure the long-term functioning and user-friendliness of the finished online store. We carry out the necessary MedusaJS platform and software updates, manage databases and provide user training. As your company’s long-term software partner, we help ensure the smooth operation, security and continuity of your online store.
