Year after, joined as Senior Software Engineer, and currently an Assistant Lead Software Engineer after last promotion. So I feel I should share my learnings (so far) from my career. Maybe freshers or juniors can benefit from it. ...

Critical Thinking (Photo Credit: eSchool News) Some people think developing “critical thinking” capability is really critical. By following proper approaches and practices, it is easy to develop. In this article, we try to explore what “critical thinking” really means and how we can develop it. What does “Critical Thinking” mean? Critical thinking is the ability to: analyze information objectively, evaluate evidence logically, identify assumptions and biases, and make reasoned decisions instead of reacting emotionally or blindly accepting information. In modern work and life, critical thinking matters more than memorization. It involves actively questioning assumptions, recognizing biases, and synthesizing information rather than accepting claims at face value. ...

Resume/CV Writing (Photo Credit: Naukri.com) A software engineering CV/Resume is not just a document listing technologies and job history.

This means they were skilled at writing code and running it with a single click of the IDE’s run button. But they didn’t know how the code was built on the server side. They should know beyond the IDE, as the server has no IDE or run buttons at all. So Rasel decided to assist them in understanding the build tools, how they work, and their importance. ...

But real-world projects are not always as straightforward and simple as they appear. During development, we constantly require multiple dependencies or services to function, such as a database, cache, message broker, and so on. Rasel realized we needed something to solve this problem. Rasel was looking for a solution that was capable of handling multiple container bootstrapping. And guess what? Rasel discovered that Docker Compose is the solution. That’s why, Rasel decided to learn Docker Compose and Docker Swarm in detail. ...
