Getting Started

Your entry point depends on your existing experience — engineers with Python and API backgrounds move significantly faster than those starting from scratch.

If You’re New to AI (0–6 months experience)

1. Master Python — Advanced proficiency is non-negotiable
2. Learn LLM APIs — Build 3–5 projects using OpenAI/Anthropic APIs
3. Understand RAG — Implement a basic document Q&A system
4. Study the Roadmap — Follow the beginner stage guidance

If You Have Software Engineering Experience

1. Audit Your Python Skills — Ensure advanced proficiency
2. Learn LangChain — This is the industry standard framework
3. Build a Portfolio Project — Choose one from the Projects page
4. Study System Design — GenAI interviews heavily test architecture knowledge

How long does it take to become a GenAI engineer?

Becoming a GenAI engineer takes 3–6 months with existing Python and API experience, or 12–18 months starting from scratch. Senior-level skills (RAG at scale, agentic systems, system design) typically require 2–3 years of production experience. See the Career Roadmap for a stage-by-stage breakdown with exact milestones.
