Top Read
AI engineer is one of the fastest-growing roles, but the path into it isn’t always clear. This roadmap breaks down exactly what to learn, in what order, and how long it realistically takes to go from your first LLM prompt to building production-ready AI systems.
You’ll cover core skills like Python, LLM APIs, RAG, and agents, along with real timelines and what the job market actually expects in 2026. If you want a focused path into AI engineering without chasing every new trend, this roadmap gives you a clear starting point.
Webinar Recording
Missed our last Project Lab? The recording is now available.
In this session, you’ll build a multi-provider LLM gateway that connects to both TogetherAI and Anthropic through a single, unified interface. Instead of locking your app into one provider, you’ll create a flexible generate() function that handles authentication, request formatting, and response parsing behind the scenes.
You’ll learn how to send direct HTTP requests, normalize different JSON response structures into a consistent output, and implement clean error handling for production-style reliability. If you’re interested in building adaptable, provider-agnostic AI systems, this walkthrough shows you exactly how to structure them.
DQ Resources
The Best ETL Tools in 2026: Learn how ETL works in practice and how to pick tools that fit your data workflows. A clear guide to making better data stack decisions.
400+ Python Practice Exercises (2026): 400+ exercises across topics and difficulty levels to help you build real coding skills step-by-step.
How to Use Lambda Functions in Python: Learn how to write and use lambda functions in real scenarios like sorting, filtering, and working with pandas.
From the Community
Synthesizer Marketplace Tool: Alberto leveraged diverse data skills to create a system that continuously monitors multiple marketplaces, derives fair market prices from real listings, and triggers instant alerts when a synthesizer is listed below its typical value.
Writing Better Project Introductions: Casandra highlights the importance of the introduction in data science projects and outlines the key components it should include to help readers quickly understand the project’s scope and results.
What We're Reading
Excel Habits to Unlearn: Small habits like overusing merged cells or cluttering one sheet can create bigger problems over time. This guide shows what to avoid and how to work more efficiently.
Pakistan Floods: EDA to Risk Clustering (Kaggle): This project analyzes flood data using EDA and machine learning to group regions by risk. A strong example of turning data into actionable insights.
3 Constraints Before You Build Anything: Before building anything, define your constraints. They help you simplify decisions, focus your direction, and avoid overcomplicating your work. A useful mindset shift for any project.
