Lenny Rachitsky, with instructor Colin Matthews, offers a practical primer for product managers who want stronger technical fluency. It walks through application architecture (client, server, database), how APIs work with GET and POST requests and hands-on practice, the software development lifecycle including Git branching, testing layers, and CI/CD deployment, and closes with questions PMs can ask when writing PRDs. The post is partly promotional for Colin's paid course.
Subscriber post — summary only01Key takeaways
- Most software is built from a client, a server, and a database, and APIs are the server's front door.
- REST APIs are the most common pattern, and GET and POST requests cover most reading and submitting of data.
- Git branches let engineers work in isolation, with pull requests and reviews before merging into main.
- Unit, integration, end-to-end, and user acceptance tests each catch different kinds of problems before release.
- Knowing CI/CD and the deployment path helps PMs reduce implementation risk and communicate better with engineers.
