Years of Experience in Generative AI Classes
4
Teaching Experience in detail in Generative AI Classes
I have four years of teaching experience, with a strong recent focus on Generative AI and Large Language Model applications. I teach learners through a practical, project-based approach, beginning with the fundamentals of transformers, tokenisation, embeddings, prompt engineering, and foundation models. My Generative AI training covers building applications using OpenAI APIs, Hugging Face models, LangChain, vector databases, and Retrieval-Augmented Generation (RAG). I guide students in developing real-world projects such as document question-answering systems, AI chatbots, text summarisation applications, natural-language-to-SQL assistants, voice-enabled AI assistants, and enterprise knowledge-search solutions. I also teach students how to prepare documents, create embeddings, perform semantic search, design effective prompts, manage conversation history, evaluate RAG responses, reduce hallucinations, and deploy applications using FastAPI, Streamlit, Gradio, Docker, and cloud platforms. My teaching style focuses on explaining complex Generative AI concepts in simple language, followed by live coding, debugging, assignments, and end-to-end projects. I support students from different technical backgrounds and help them gain the practical skills required to build reliable Generative AI applications independently.

Teaching Experience in detail in Full Stack Agentic AI
I have four years of teaching experience in Artificial Intelligence, Python, Machine Learning, Generative AI, and Agentic AI. My Full Stack Agentic AI training focuses on building complete, real-world AI applications from frontend to deployment. I teach students how to develop AI agents using Python, Large Language Models, prompt engineering, tool calling, memory, RAG, vector databases, LangChain, LangGraph, and multi-agent workflows. The training also covers backend development using FastAPI, database and API integration, and frontend development using Streamlit or Gradio. Students learn how to connect AI agents with documents, databases, external APIs, and business tools. I also cover evaluation, hallucination reduction, guardrails, logging, Docker, cloud deployment, and basic LLMOps concepts. My teaching approach is practical and project-oriented. Students complete hands-on assignments and end-to-end projects such as RAG chatbots, SQL agents, customer-support agents, document-analysis systems, and voice-enabled AI assistants. I explain every concept in simple language and connect it with real industry use cases.

Hi Priya,
I suggest you try a Data Science career as it is the trending domain.
Data Scientists, Data Analysts and Business Analysts are needed in every organization and each domain. So many positions are getting outdated because of automation happening in every field due to the emergence of Data Science and AI.
You must be aware of Data Explosion that is happening, and the fields related to Data are much in demand despite the pandemic situation. In Human History, 2018 to 2020 have been remarkable years where 400% of the increase in digital traces have been observed. New tools and technologies related to Big Data Systems, Cloud Computing, Data Science & Artificial Intelligence have emerged, helping data storage facilities, making data available at a fraction of costs; analytical tools like Python, R, Hadoop, Tableau, Power BI providing analytical platforms.
I suggest you consider this field because the future is all Data, and many jobs will be lost, and many will be created due to Data emergence.

Hi Bharti,
You have made the right decision to move to the Data Science domain at the right time, but you should be well aware of what you need first. If you want to go as a data scientist, learn Statistics, Python or R for Data Science, Machine Learning, Tableau and Hadoop.
If you want to choose Artificial intelligence, learn Python, Tensor flow Keras, Natural Language Processing, Advanced Computer vision with Advanced Machine Learning and Deep Learning.
If you want to go as a data/business analyst, you need to learn, Tableau or Power BI, Stats, SQL.
Good Luck!
