Reduced processing time from two hours to under three minutes to process a 2GB file that had pricing of various products within a supermarket using Spring Batch framework. Worked with more than 50 pairs in a pair-programming program and acquired skills from different developers. Automated builds using Jenkins and GoCD and introduced continuous integration and continuous delivery to the team.

Fixed several issues in various parts of the application. Launched a small business store for a travel booking platform with custom styling and built-in Vue with the back end in PHP and Go. Led a team of approximately 15 and managed the complete end-to-end delivery.


We have different projects, different problems, and different architectures, so knowing multiple programming languages, enables you to be more productive and efficient. From a business perspective, we should first think about solving an actual business problem and only then pick the methods and ways to cover actual needs. However, integrating a wide variety of languages into a single application may entail added complexity.

Being able to learn a new language or framework is crucial and achievable with documentation and community support. If you choose to work in tech, you enter the learning never stops zone where every day is a new opportunity to improve and acquire more skills. By ignoring this key principle you risk becoming outdated. Keeping up with the latest advancements is a challenge on its own and if you don’t have a life-long learning mentality you will not enjoy it. It’s easy to get settled in the comfort zone with your current language or framework, this is understandable, it’s our human nature to stick to familiar.

While the programming language is one of the oldest, it is still very relevant when it comes to modern development, more particularly mainframe development. ITNEXT is a platform for IT developers & software engineers to share knowledge, connect, collaborate, learn and experience next-gen technologies. Unless you are preparing to enter big tech company or mission critical software producers, for most programming tasks, you only need to deal with the collections, not the underlying data structures. This is because every programming language provide collections that are implemented in most possible efficient manner for general purposes.

The goal is to improve ourselves, not to be focused only on one technology stack, to be able to use the best tools for the job, and to be able to think differently and see the bigger picture. Rust and Go both offer language features geared toward microservices-based development, but their relative capabilities make them… For example, we are trying to follow a 12-factor app strategy. Our applications do not aware of the underlying tech about logging. All our microservices print their logs to stdout, and we collect them with fluentbit/fluentd in kubernetes.

Keeping the team informed

However, this is not practical in the world of web development. Not only do you have to keep up with what’s current and evolving, but you also have to stay on top of the latest industry trends. Highly flexible or extensible file formats have greater scope for polyglotting, and therefore more tightly constrained interpretation offers some mitigation against attacks using polyglot techniques. This creates a window of opportunity for polyglot PDF files to smuggle non-PDF content in the header of the file. These days sticking to a single technology/programming language/tool is not enough for a developer. There are so many things to consider, especially in the microservices world.

Developed a matrimonial product that would help bridge prospective profiles and grew it from 1 to 200 paying customers every month . In the previous episode, Marek and I discussed the history and use-cases behind virtual machines, containers, and bare metal deployments. We briefly discussed orchestration, but ran out of time when it came to getting into the exciting topics. You have experience with large-scale distributed systems and micro services architecture. Like to collaborate with other engineering teams in coming up with and implementing product features. Shifting to the DevOps model can be complicated and challenging.


There are so many other parts to consider while developing an application. Like eventual consistency, event sourcing, circuit breaker, retries, distributed locks, saga, state machines, etc. We need to follow clean code practices to write clean, understandable, readable code. You only need to tweak the data structures if you have need for high-performance needs , custom device constraints (less memory/processing power), or both. When you want to tweak “Hello World” into “olleH World”, being familiar with C++ version will take you off like a jetliner. But being a java programmer, you will be fumbling the docs to see if there is any reverse() to suit your custom needs.

  • The goal is to improve ourselves, not to be focused only on one technology stack, to be able to use the best tools for the job, and to be able to think differently and see the bigger picture.
  • Then, they learn everything they can about that language and, hopefully, continue their journey coding software using what they’ve learned.
  • Use what gets the job done, remember, unlike what some people might say, there is no problem with doing OOP or imperative code.
  • Set your team up for success by learning which areas to …

Resource consumption may increase in terms of training, testing and maintenance. Polyglot programming may also make code difficult to deploy How to Hire an App Developer for Your Business if operations is not familiar with the same languages used in development. Most programming languages are quite similar at their core.

Learn about the latest trends in web, mobile, and game development and how you can quickly get ahead in becoming an incredible developer. Historically, all programming languages after Assembly, including C++, have been termed as high level languages. Anything that abstracts the programmer from writing machine code is a high level language. A generation of programmers believed that hero developers are polyglot programmers — a breed who has mastery over multiple, even unrelated programming languages. As the saying goes don’t keep all your eggs in a single basket. There are considerable effort and some disadvantages to being a polyglot developer.

The times when we could focus on one programming language are long gone. Even in one project we may face a backend written in Java, an Android app in Kotlin, an iOS app written in Swift, and maybe a Web client in JavaScript. Most programming language share a lot of common concepts, yet they differ regarding implementation. In the past, the common view was that having a uniform ecosystem is better than the overhead of a variety of frameworks.

Yet, it wrote its iOS News Feed screen using Objective C and C++ to gain the ultimate performance + customization advantage. In 1990s, for example, rise of Java almost obliterated the need for memory management. This resulted in low-performance web applets that reined due to a parallel rise in hardware capabilities and internet bandwidth.

Use a good IDE/Editor/Plugins to take care of language syntax and style for you. A programmer shouldn’t be worrying about inserting semicolons and commas or adding the right amount of tabs or spaces. Connect to a PostgreSQL Database Server It’s 2020, these things should be the least of your concerns, let the IDEs or tools like prettier & linters take care of those. For the last time, it friggin doesn’t matter if you use tab or space.

So in the IT industry when someone says s/he is a polyglot developer they mean they can work with a handful of languages at least and they don’t have any particular strong preference for a single language. It seems that today, more than before, developers are less likely to stay with a specific programming language, and, instead, choose to move between them based on the tasks they need to accomplish. A polyglot developer can work with multiple languages with ease.

Other DSLs such as SQL , XML and CSS are often built into enterprise applications as well. One developer may be proficient in multiple languages, or a team with varying language skills may work together to perform Top 10 JavaScript Online Courses for Beginners in 2022 Best of Lot polyglot programming.
