Cursor 2.0 dropped last week, and unlike most recent AI updates, it's actually changed how I work. Two features in particular: Cursor's new Composer model that's 10-50x faster than any other coding model, and parallel agents that finally make running multiple autonomous builds practical. I'll show you Composer building and...
Claude just launched Skills across all their platforms, and I've spent a week testing the Claude Code implementation specifically. Do Claude Code Skills actually solve problems developers have, or are they better suited for consumer platforms like Claude.ai? I compare Skills to the developer tools we already use...
I demonstrate my workflow for running multiple AI coding agents (Claude Sonnet 4.5 and Cursor's Composer 1) in parallel on the same feature, then comparing their work to choose the best implementation. The focus is on solving the practical challenges of reviewing agent work in git worktrees by using a branch-based approach that makes testing, debugging, and merging much more manageable.
In this video, I show how to build a fully automated PDF invoice system in Rails—from Stripe test data to downloadable invoices—using Cursor 2.0 and their new Composer model.
In this video, I walk through the implementation of a complex member profile feature for our platform, which includes user-generated usernames, experiences, and interests. After testing, I encountered some issues, particularly with the display and functionality of these features, which I addressed with the help of AI. I also made...
Remember what FLOW used to feel like? Hours would disappear. It felt amazing—that perfect flow state where you're crafting software with your hands. Well I'm noticing a new flow emerging when I'm building products using AI. I'm finding that this new rhythm of development has a repeating 3-step cycle.
Claude Code forgetting things? The key is to manage Claude Code's context window—a.k.a. Context Engineering. This video covers how to be more efficient with your context useage, primarily by marking use of Claude Code's new Subagents feature (game-changer!). You'll also uncover a few hidden gem tips I packed into this one.
Claude Code is excellent as an autonomous coding agent. So the obvious next step is to run multiple Claude Code agents in paralell. Simple, right? This video shows you how to use Git Worktrees and my method for automating the workflow for spinning up new worktrees to run multiple Claude Code agents simultaneously.
As professionals, we have to master our tools. My daily driver for coding and building with AI? Cursor (a fork of VS Code). So I'm sharing all most frequently used Cursor keyboard shortcuts, how I've customized them and how you can customize your shortcuts in Cursor (or VS Code).
