AI Engineer Kaise Bane — Beginner to Job Ready Roadmap

SECTION 01AI Engineer Kya Karta Hai — Role Clarity

AI Engineer ek hybrid role hai — Data Scientist + Software Engineer + MLOps Engineer.

Daily responsibilities:

• Model Development: ML/DL models design, train, aur optimize karna.
• Data Pipelines: Data collect, clean, aur process karna.
• Gen AI Apps: LLM-based applications build karna — RAG, agents, chatbots.
• Deployment: Models ko APIs mein wrap karna, Docker + cloud deploy karna.
• Monitoring: Model drift, performance, aur business KPIs track karna.
• Collaboration: Data scientists, DevOps, product managers ke saath kaam karna.

AI Engineer vs Data Scientist vs ML Engineer:

• Data Scientist: Analysis + modeling, business-focused.
• ML Engineer: Model deployment + scaling, engineering-focused.
• AI Engineer: Broad — models + Gen AI + deployment, end-to-end.
