BMaiKR - Workflow Marketplace & Multi-Tenant Execution Engine
Project Overview
The Challenge
Businesses need a centralized way to discover, purchase, and immediately deploy complex automation workflows (via n8n and customized APIs) without needing to understand the underlying code. The challenge was architecting a marketplace that securely handles multi-tenant data, user provisioning, and real-time execution routing.
The Approach
This required an advanced system design mapping user authentication directly to infrastructure provisioning.
The Request Pipeline:
User request → API authentication → workflow provisioning → isolated n8n execution → ledger sync, with every step logged for auditability.
Performance Outcomes
Results & Impact
Outcome
The BMaiKR Workflow Marketplace is now capable of executing thousands of asynchronous background workflows securely while keeping creator and buyer ledgers perfectly synced.
"Building an execution platform requires shifting from standard CRUD operations to event-driven architectures. Handling API failures, dead-letter queues (DLQ), and secure state management is what separates a prototype from a production-grade SaaS product."
Engineering Notes
System Architecture
Built a sovereign EU cloud infrastructure for deploying private AI models and n8n automation workflows, strictly bypassing US-based LLM APIs to maintain absolute GDPR compliance.
Technical Hurdles
Integrating disparate low-code/no-code platforms while ensuring strict data privacy required custom API middleware and isolated Docker containers for the AI engine.
