🎯 Learning Paths

Path 1: Engineer → LLM Production Specialist (3-6 months)

1. LLM fundamentals and token economics — what models cost and why
2. Prompt engineering and prompt testing frameworks
3. Build a RAG pipeline with a vector DB and retrieval tuning
4. Deploy LLM inference with autoscaling and monitoring

Outcome: Ship a reliable LLM-backed feature and own its SLA and cost.

Path 2: Researcher → MLOps Lead (4-8 months)

1. Model training fundamentals and experiment tracking
2. Feature stores and data pipelines for model inputs
3. Continuous evaluation and model promotion pipelines
4. SLOs for model quality and observability

Outcome: Run reproducible model training and safe promotion to production.

Path 3: Product Manager → AI Product Builder (2-4 months)

1. AI capability ideation and user impact mapping
2. Cost/benefit analysis for LLM features (latency vs quality)
3. Risk assessment: safety, compliance, and data privacy
4. Operational metrics and experimentation strategy

Outcome: Define and prioritize AI features with measurable outcomes.

Path 4: Architect → Agentic Systems Designer (4-9 months)

1. Multi-agent design patterns and coordination models
2. State management and long-term memory architectures
3. Observability and human-in-the-loop controls
4. Security, least privilege, and failure modes

Outcome: Design scalable, auditable agentic systems.
