Certified Alfresco & Vaadin Dev | n8n Automation (n8n, BPMN)

I help companies turn messy, slow internal processes into fully automated systems. For 12+ years, I’ve been working with Alfresco and Vaadin, building document management systems and internal tools. Today, I combine that experience with n8n to automate workflows across multiple systems - without overengineering. ✅ What I actually do: - replace manual document handling with automated flows - connect systems that don’t talk to each other - build internal tools your team will actually use - eliminate bottlenecks in approval and operations processes 💪 Typical stack: n8n | Alfresco | Vaadin | Java | NodeJS | SQL | APIs | S3 | LDAP | BPMN 🎯 Clients usually come to me when: - processes are slow, and people are doing repetitive work - document workflows are chaotic or fragile - integrations are missing or poorly implemented - they need a senior engineer who can design the system, not just code Selected results: - automated document approval workflows with external storage (S3) - built internal tools used daily by operations teams - reduced manual work by automating cross-system processes I work directly, go deep into your system, and take responsibility for the result. If you're serious about automation - let’s talk.
