Building Full Stack Apps With Cursor Composer
Workshop
Mike Mikula
Mike Mikula
In this workshop I’ll cover a repeatable process on how to spin up full stack apps in Cursor.  Expect to understand techniques such as using GPT to create product requirements, database schemas, roadmaps and using those in notes to generate checklists to guide app development.  We will dive further in on how to fix hallucinations/ errors that occur, useful prompts to make your app look and feel modern, approaches to get every layer wired up and more!  By the end expect to be able to run your own AI generated full stack app on your machine!

How to 9,2x Your Development Speed with Cline
Workshop
Nik Pash

The way we write code is fundamentally changing. Instead of getting stuck in nested loops and implementation details, imagine focusing purely on architecture and creative problem-solving while your AI pair programmer handles the execution. In this hands-on workshop, I'll show you how to leverage Cline (an autonomous coding agent that recently hit 1M VS Code downloads) to dramatically accelerate your development workflow through a practice we call "vibe coding" - where humans focus on high-level thinking and AI handles the implementation.You'll discover:The fundamental principles of "vibe coding" and how it differs from traditional developmentHow to architect solutions at a high level and have AI implement them accuratelyLive demo: Building a production-grade caching system in Go that saved us $500/weekTechniques for using AI to understand complex codebases in minutes instead of hoursBest practices for prompting AI agents to get exactly the code you wantCommon pitfalls to avoid when working with AI coding assistantsStrategies for using AI to accelerate learning and reduce dependency on senior engineersHow to effectively combine human creativity with AI implementation capabilitiesWhether you're a junior developer looking to accelerate your learning or a senior engineer wanting to optimize your workflow, you'll leave this workshop with practical experience in AI-assisted development that you can immediately apply to your projects. Through live coding demos and hands-on exercises, you'll learn how to leverage Cline to write better code faster while focusing on what matters - solving real problems.

In this workshop, we’ll explore how to manage application configurations directly in your Git repository and integrate them into the TypeScript type system. The goal is to make your code aware of the actual configuration at compile-time, reducing the need for runtime validation and unit tests.You'll discover:How to create lossless types for static dataTechniques to eliminate unnecessary code paths and reduce runtime validationHow to leverage utility types to extract specific information from configurationsKey TypeScript operators and how to handle common pitfalls when working with generic typesBest practices for improving type safety and developer experienceBy the end of this workshop, you'll have a solid understanding of how to implement Config as Code in your TypeScript projects, enhancing maintainability, type safety, and autocomplete support. This workshop is ideal for TypeScript developers looking to optimize their code and streamline configuration management.
