Custom B2B SaaS software development for transport, logistics and operations

Cargoffer offers consortium partners its product engineering capability for building custom B2B SaaS applications in the transport, logistics and operations domain. Our team ships and operates multiple production SaaS products used daily by more than 5,000 transport professionals across Europe, including a Transport Management System, a freight marketplace, an electronic consignment notes platform, an OCR service for logistics documents, and the TRANSCEND route optimisation platform.

We contribute expertise in:

• End-to-end product engineering: from domain modelling and API design to frontend, backend, infrastructure and operations, with a track record of taking products from zero to production-scale.

• Frontend engineering for B2B SaaS: React, Vue, Astro and TypeScript, with a focus on SEO-first public surfaces, accessible and mobile-first dashboards, and component libraries that scale to dozens of internal tools.

• Backend engineering: TypeScript/Node, Python (FastAPI) and Go, with experience operating MongoDB, PostgreSQL and event-driven architectures at European scale.

• API-first design and documentation: OpenAPI 3.1 specs as the contract between frontend, backend and external integrators, interactive documentation portals, and SDK generation.

• DevOps and infrastructure: containerised deployments, manual deploy pipelines with versioned environments (dev / release / main / demo / edu), observability practices, and a strong preference for reproducible builds and minimal-magic operations.

• Document and data extraction: production OCR pipelines for logistics documents, including schema validation, confidence scoring and human-in-the-loop review flows.

• Multilingual product surfaces: ES, EN, PT, FR, DE, IT, with locale-aware UI, data formats and compliance considerations.

We are open to contributing this engineering capacity to Horizon Europe 2026-2027 consortia that require custom software work — whether as a Work Package lead (delivering a specific product or service within the project) or as a technical partner providing capacity to academic or public-sector coordinators. We are particularly strong when the project outcome is a usable, production-grade software artefact rather than a research prototype.
