About Me

image of myself

Freelance Software Developer & Technical Author

I am a software developer and a technical author based in India. I love to build robust and scalable MERN applications to solve problems and automate repetitive tasks. When I am not working on a software problem, I prefer to spend my time learning and writing content on technical topics.

I have been active as a freelance technical author for over two years. I have worked with an array of clients in the application performance management and machine learning industries. I prefer creating long-form content as it provides the audience with ample information on the topic as well as performs well in SEO. I have extensive experience in writing long form content as well as web copies with relevant technical and marketing research.

The Developer’s Guide to SOLID Design Principles

Building stable and robust software is one of the primary goals of any software development project. While it is crucial to keep your code error-free for that, the real strength of your application comes from its foundation—the architecture of your code. In this guide, we will take a look at these design principles in detail.

Using aliases in GraphQL

Using aliases in GraphQL

If you’ve used GraphQL for your production application, you may have encountered a scenario where you needed your custom queries to return custom field names. Or, maybe you received two query results in the same server response, causing the field names to clash.

Premature Optimization: Root of All Evil or Rationalization?

Premature Optimization: Root of All Evil or Rationalization?

Premature optimization refers to the process of making a piece of code more efficient when it is too soon to guarantee an optimization. To make it more clear, when prematurely optimizing, you usually spend a lot of time and resources working on parts of your code that will have a negligible impact on the outcome rather than on those things that will heavily affect the final results. Such measures almost always backfire since you miss out on perfecting the metrics that truly affect your business.
