A visual deep-dive into running Celery workers as separate ECS containers — broker topology, task lifecycle, concurrency models, and the Beat scheduler gotcha.
Alex Beattie | Senior AI/LLM Engineer
I build production AI products from 0 to 1: Stella at Ourself Health and KiNDD / NDD Resource Navigator. My work spans scalable Django/Python backends, AWS Bedrock, Strands agents, Langfuse observability/evals, RAG pipelines, cost-aware model routing, GraphQL APIs, Flutter-connected mobile platforms, and the operational details that make AI products dependable after launch.
Start here:
- Production AI routing and evals for a healthcare assistant
- Bedrock, pgvector, and RAG lessons from production
- Streaming LLM architecture patterns for sources, done events, and observability
- KiNDD / NDD Resource Navigator project case study
- Unified Connectors MCP Server project
- Geospatial care-navigation for developmental disability services
- AI assistance for a public-interest healthcare navigator
- AI engineering background and focus areas
