MLOps Engineer - LLM & Python Microservices Pipelines
I design and operate AI pipelines in production: multi-LLM orchestration, inter-provider routing, embeddings and vector search, multimodal OCR, agentic agents. Obsession: 24/7 reliability and cost per request.
Stack & Topics:
- LLM Ops: multi-model orchestration via aggregator gateway, 4-provider chain with automatic fallback, cost tracking per call
- Agentic Pipelines: tool use, grounding by evidence, JSON repair, parallel multi-judge juries
- Vector & RAG: open-source embeddings, pgvector halfvec for dedup and semantic search, knowledge graphs
- Python Backend: FastAPI, Valkey/Redis (queues + pub/sub), PostgreSQL, SQLite
- Infra: Docker, EU cloud, private VPN, real-time monitoring, atomic Lua rate limiting, HMAC auth
- Modalities: multimodal OCR, audio transcription with fallback
Projects in prod:
MODOX - 16 Python microservices communicating via Valkey, 9 LLM models distributed across 10 providers with automatic fallback, agentic agent with tool use and datagouv grounding for company classification.
Lucien APP + Lucien_BOT - AI tool and autonomous agentic recruiter: 17 skills, 4 specialized sub-agents, LinkedIn integrations + job aggregator + public ATS, dual backend PostgreSQL + SQLite, knowledge graph, real-time dashboard, integrated GDPR.
Observatoire Rodrigue - multi-agent editorial pipeline: ~22 articles/week, 4-pass writing + jury of 3 parallel judges, 11 orchestrated sub-phases with controlled budget per article.
ClearMind Proxy - HMAC FastAPI gateway between mobile apps and LLM providers, 2-layer rate limiting.
Currik - CV builder with multimodal OCR in production.
Work approach:
- 30 min scoping before quoting
- Cost/latency/uptime tracking from day 1
- Fallback chains rather than naive retry
- Concrete milestones, daily check-ins
- Available for short (audit, benchmark) or long missions.
