About Julian Niklas

I help companies deliver successful integration projects by aligning business goals with technical execution. As a Product Owner and Integration Architect, I translate requirements into actionable delivery plans and ensure that integration solutions actually support business outcomes.

With 6+ years of experience across enterprises and SMEs, I take ownership of requirements, backlogs, and stakeholder communication while also designing and guiding the implementation of API-based integrations with focus on MuleSoft. This includes API design and implementation, ensuring governance, and supporting teams during development and rollout.

Customers work with me when they need someone who can keep delivery moving, ensure technical feasibility, and make sure that business and IT stay aligned — from prioritization and solution design through to successful go-live.
