NexusFlow — Distributed Job Orchestration & Automation Engine

NexusFlow | Distributed Job Orchestration Engine

Problem: Applications often need to execute long-running tasks reliably without blocking API requests. Tasks can fail, workers can crash, and duplicate execution can create inconsistent results.

Proposed Solution: Build a distributed job orchestration system that accepts tasks, schedules execution, distributes work to background workers, and provides reliable execution tracking.

Core Features:

• Job submission API with priorities, scheduling, and execution metadata.
• Worker registration, task claiming, heartbeats, and concurrency limits.
• Retry policies, exponential backoff, timeouts, and dead-letter handling.
• Idempotency keys to reduce duplicate side effects.
• Job dependencies and multi-step workflow execution.
• Live job status updates and execution logs.
• Worker health monitoring and failure recovery.
• Docker-based local cluster with automated integration tests.

Technology Stack: MongoDB, Express.js, React.js, Node.js, Redis, BullMQ, WebSockets, Docker, Docker Compose, GitHub Actions.

Engineering Focus: Distributed task processing, queue semantics, concurrency, failure recovery, observability, and API design.
