Build a practical semantic search system with Python and Sentence Transformers. Learn how text becomes embeddings, compare queries with documents, rank results by similarity, and turn the prototype into a reusable search component.

Learn how to use Wireshark to capture and analyze network traffic. Understand packets, protocols, display filters, TCP conversations, DNS requests, HTTP traffic, and a practical troubleshooting workflow.

Learn how to approach coding interview problems step by step, explain your reasoning clearly, choose an efficient solution, test edge cases, and communicate trade-offs without freezing during the interview.

Learn how real data science starts before machine learning. Work with a messy sales dataset in Python, clean missing and inconsistent values, explore patterns with pandas, visualize business trends, and turn raw CSV data into practical recommendations.

Build a real sentiment analysis application with Python and Hugging Face Transformers. Learn how pretrained NLP models work, run inference locally, interpret confidence scores, process multiple reviews, expose the model through an API, and understand when sentiment models can fail.

Already have a Node.js API and wondering whether it can run without a traditional server? Learn how to move a small API endpoint to AWS Lambda, expose it through API Gateway, handle environment variables, structure the handler, and avoid common serverless mistakes.
