The Data Engineering Handbook

AI Engineering Lab is a free, self-paced 24-week AI engineering course developed by Zorost Intelligence AI Lab. It takes learners from Python and machine learning through deep learning, LLM internals, prompt and context engineering, retrieval-augmented generation with vector search, quantization, LoRA and DPO fine-tuning, evaluation harnesses, coding-agent harnesses, AI agents, MCP, and cloud and Databricks platforms including Azure AI Foundry, Google Vertex AI, AWS Bedrock, and Databricks. The curriculum uses one continuous fictional freight-company case study. Each week pairs a concept with a runnable Python, SQL, or PySpark artifact; from Week 3 onward, the work includes a metric and an error note. The repository contains 43 runnable notebooks, publishes the full curriculum online, requires no signup or paid API key, and states that the first eight weeks require no GPU. It is MIT licensed.

AI Engineering from Scratch is a free, open-source curriculum developed by rohitg00 for learning to build and ship AI systems end to end. Its 20-phase sequence covers development tooling, mathematical and machine-learning foundations, deep learning, NLP, computer vision, generative AI, LLM applications, agent engineering, Model Context Protocol (MCP), agent skills, reinforcement learning, and related topics, with implementations in Python, TypeScript, Rust, and Julia. The repository describes 511 lessons and approximately 329 hours of material; each lesson produces a reusable artifact such as a prompt, skill, agent, or MCP server. Learners are instructed to read the lesson documentation, type and run the code from the repository root, record command evidence and outputs, and make a small change before continuing. It provides routes for complete foundations, mathematics and machine learning, production LLM applications, agent engineering, MCP, agent skills, and Claude certification preparation. The repository is distributed under the MIT license and is accompanied by a website containing the same lesson content.

Databricks is a unified platform for data, analytics, and AI. It supports ETL, data warehousing, governance, and AI workflows through a data-centric platform. The videos describe its use for security detection, organizational ontologies, agents, and internal enterprise AI workflows.

digoal/blog is a repository-hosted technical blog and learning resource maintained by digoal. It covers PostgreSQL, Greenplum, databases, open source, AI, business, finance, and related topics through categorized articles, video courses, tutorials, source-code study series, operational guidance, and reading notes. The repository is actively updated with new posts and learning collections, including database internals, vector and hybrid search, AI agents and memory, PostgreSQL extensions, investment, and philosophy.

Data Agent Kit is an editor extension for working with data operations. It supports viewing data jobs, executing saved queries, monitoring data-flow and Spark jobs, running notebooks, and accessing data services.
