Apply NLP fundamentals including tokenization, embeddings, and semantic similarity for text generation, summarization, and classification tasks.

Automate workflows using Python and integrate APIs, ensuring structured outputs with JSON.

Proficiency with platforms such as OpenAI, Google Vertex AI, or similar.

Solid Python skills for automation and API integration.
