AI Vibe Coding Best Practices, Local Models and Data Privacy

Most of the competition is not teaching you what you will learn here, and unfortunately this pass unnoticed because I don't sell 100+ generic courses and my promotion is low.! They show you one provider (claude, codex), but not how to understand LLM under the hood (choosing and configuring models).! They show you prompts for specific projects unrelated to your interests, instead of explaining how to optimize your agentic coding workflow for any project.You're about to discover a smarter approach to AI-assisted coding directly in VS Code or JetBrain: one that prioritizes engineering discipline, cost efficiency, and future-proof independence over quick fixes and subscription lock-in.You'll learn to read hardware benchmarks, optimize API usage, configure local models, and implement professional workflows that scale from personal projects to enterprise applications.Through a complete real-world project, building an in-browser 3D TicTacToe prototype and performing code maintenance, you'll master the full development lifecycle with AI assistance.The course includes configuration templates, system prompts, and detailed instructions that work across tools—even Cursor, since you can use Cline and Continue inside it.Why This Approach MattersCost: While most developers use or plan to use AI tools, industry research reveals significant concerns: 53% cite platform costs as a barrier (reaching $100 monthly or more, during high-use phases).Privacy: Another 53% view AI as a data-privacy threat, and 46% actively distrust AI accuracy. This course addresses these challenges by teaching you to work with local models and systematic engineering practices.What You'll LearnLearn hardware optimization and model selection for cost-effective developmentSet up local models with LM Studio for unlimited usage and full dat
