About

In the realm of app development, the path to success often begins with crafting a Minimum Viable Product (MVP) – a streamlined version of your app that focuses on delivering core functionalities to early adopters. But how do you determine which features should make the cut for your MVP?

As a developer constantly striving to streamline workflows, accelerate delivery, and improve user experience, integrating AI into my development process wasn’t just exciting — it was transformative. This is a case study of how I integrated ChatGPT into my development toolkit and product workflows, and how it continues to impact my coding, debugging, architecture decisions, and even communication with non-technical stakeholders.

How I Use ChatGPT as a Developer

Here’s how I practically use ChatGPT every day:

1. Code Generation & Scaffolding

Instead of manually writing repetitive code, I now use prompts like:

Generate a RESTful Express.js API with JWT auth for a user management system.

ChatGPT gives me a working scaffold — routes, middleware, and sometimes even a .env suggestion.

2. Debugging Help

When I encounter a stubborn bug, I copy-paste the error log and affected code into ChatGPT.

It often spots what I’ve overlooked:

  • A mismatched bracket

  • An async/await misuse

  • A missed return statement

This has significantly reduced debugging time.

3. Code Reviews and Refactoring

I paste in my function or component and ask:

Can this be optimized or made more readable?

ChatGPT highlights improvements like:

  • Avoiding nested loops

  • Breaking large functions into smaller ones

  • Replacing var with let or const

4. Learning New Tech

When I moved from Vue 2 to Vue 3 + Composition API, I used ChatGPT as my trainer.

It explained differences, rewrote examples, and provided migration tips.

Now, I’m learning Angular with it too.

5. Writing Documentation and Comments

Instead of wasting mental energy, I ask ChatGPT:

Add JSdoc comments to this function
Write usage documentation for this API endpoint.
