What to Think About Before Using ChatGPT Professionally

Before we fully embrace the revolutionary capabilities of ChatGPT in a professional context, it’s essential to take a moment to consider that it can be a double-edged sword, understanding its nuances, limitations, and ethical implications is paramount.

A lot of ethical and security topics have been emerging since its origin, a lot of controversy has been lying around this tool. With a great power comes great responsibility, and ChatGPT is no exception. 

One remarkable occurrence was within Samsung, which caught some software engineers pasting proprietary code in the search of some answers.

This is one of the many dangers underneath such an amazing tool, and which we will be addressing in the following article, so stay tuned!   

9 ChatGPT Practical Applications for Developers


In the world of software development, staying ahead means embracing innovation. ChatGPT goes beyond conventional AI, offering developers a spectrum of practical applications.

In this section, we’ll uncover how it can elevate coding, debugging, idea generation, and more, redefining how developers interact with technology and each other.

Welcome to the realm of hands-on AI integration, where ChatGPT becomes a developer’s valued companion in the pursuit of excellence.

1. Code Assistance and Generations

You’re working on an assignment which requires you to come up with a complex sorting algorithm to organize a given dataset.

Before: You’d spend some hours researching and implementing some samples which would eventually allow you to narrow down the most appropriate one.

With ChatGPT: You’d describe the desired sorting behavior. The model would then provide you with a sample code snippet using sorting algorithms and suggesting which one should you peek at.

2. Debugging Support

You encountered a baffling bug that’s evading your usual debugging techniques.

Before:  Reach out to an available coworker that might give you a hand by supplying another perspective.

With ChatGPT: You’d describe the issue. The model would then offer insights into potential reasons, such as incorrect memory access, missing considerations, guiding you towards a solution.

3. Idea Brainstorming

You’re brainstorming features for a new mobile app.

Before: Invest some time over research, try out apps you’re currently using, reach out to other developers to get their opinion.

With ChatGPT:  Describe your vision, the app’s purpose and current functionalities. The model will offer suggestions and improvements, it should help refine your ideas and explore different angles.

4. Learning and Skill Enhancement

You’ve been working with Java, but now you’re eager to learn Python.

Before: Research for some useful courses and books which will introduce you to the language. Invest the time by going through those.

With ChatGPT: Describe what you intend to learn, which level you consider to be in, which path to follow. The model will offer you examples of resources which you might use, show you practical examples, and also suggest potential projects to accelerate your learning process.

5. Code Reviews and Suggestions

You’re reviewing a codebase, and you come across a complex section of code that seems unclear or poorly optimized.

Before: Brainstorm with the codebase’s owner about possible changes, try out several approaches. This would consume a significant amount of time on experiments.

With ChatGPT: Paste your code, be careful to change any business private details, and ask how you could optimize such snippet. You’d instantly get recommendations about alternative implementations or best practices.

6. Architecture and Design Discussion

You’re designing a software architecture.

Before: Traditional discussions with limited access to expertise and scheduling constraints.

With ChatGPT: You could start a discussion any time, without schedule constraints, regarding several aspects of your view and still validate your reasoning.

7. Summarise Documentation

You have to implement a complex API into your project. You receive a comprehensive, but lengthy, API documentation manual. As you start reading it, you realize that it’s filled with technical jargon and lengthy explanations. 

Before: You spend hours sifting through the documentation, trying to extract the key information that you need to integrate the API into your project effectively. It’s not only time-consuming but also mentally exhausting. 

With ChatGPT: You request the model to “summarize the key features and usage of the API”. In a matter of seconds, you get prompted with a concise and clear summary of the documentation, highlighting the essential functions, parameters, and usage guidelines. 

8. Automated Code Refactoring

You’re working on a legacy software project with a massive codebase that has accumulated technical debt over the years. Your task is to refactor a particular module to improve its performance and maintainability.

Before: You manually review the code with the goal of identifying the components with redundancy, complexity, deprecated practices. You manually refactor each piece considering the optimisations and maintainability requirements.   

With ChatGPT: You paste the code, hiding its business details, and ask ChatGPT to “refactor by improving performance, readability, and flexibility”. It will analyze the code, identify which areas need improvements, and it generates some refactoring suggestions. You can always suggest working on it again until you’re satisfied with the quality.

9. Code Generation for Prototyping

You were asked to create a quick prototype for a new feature in your application.

Before: You’ve manually written code from scratch, configuring libraries, and defining the project’s structure on the way. After a while, you get there, however with the cost of time, especially when you needed to try out your different ideas.

With ChatGPT:  You have a clear vision for your prototype but want to speed up the initial development phase. So you request the model to “Generate a prototype for feature X” based upon your requirements. Within minutes, you have a working prototype that you can start testing and refining immediately.

The Practical Engineer’s Toolkit


In such a fast-paced software engineering landscape, this tool emerges as an invaluable tool, which empowers our efficiency and creativity. 

From code assistance and debugging support to generated documentation and quick prototype generation, ChatGPT adds a powerful layer to the practical engineer’s toolkit. It will continue to reshape our approach to software development, offering new possibilities and innovations every day. 

It’s essential to be mindful of its capabilities, and, just like any powerful tool, it comes with hidden dangers. In next article regarding ChatGPT, we will explore the ethical considerations, potential biases, and security concerns associated with integrating AI like ChatGPT into our workflows, ensuring that we navigate this technology responsibly and effectively.
