Technology Stack To Build A HR Tech Company

People and technology are two of the most important aspects of any organization. Many of the difficulties that one faces in HR may be addressed with technology and performance management, including monitoring employee engagement and job satisfaction, performance management and recruitment.

Long-term remote working has become more common as a result of COVID-19. To defeat this problem, we need to use technology and all of the tools at our disposal.

HR software is designed to assist employers and employees in making their lives simpler in the workplace. HR software streamlines every aspect of operating a firm, from recruiting top personnel to managing their salary and benefits to creating individualized career paths.

Use Of Technology To Transform HR

In the present age of Software-as-a-service (SaaS), new tools for HR professionals have become readily available and the current software is always progressive. While this is exciting and valuable, navigating through the vast array of alternatives accessible to HR professionals may be intimidating.

For practically every type of application you create, the technology stack is one of the major concerns. When choosing a technological stack for your HR software, you must evaluate projected bandwidth consumption, web app type, business goals, and possible extensibility.

When it comes to HR software development, the process of selecting a technology stack is no different, and it is vital for its future commercial success. Applications in that segment have unique requirements that can only be satisfied with the right mix of technological components.

However, not all HR apps demand the same level of attention when it comes to their tech stacks. Simple apps that cater to a limited user base and have only a few features will most likely do well with whichever stack best suits their needs.

Selecting A Technology Stack

So, the first question that arises is what type of technology stack would be appropriate for a complex multi-user HR application? Before we answer this question, we have to look at the most significant features of those apps and compare them to the technology that can match those requirements.

When we look at prominent HR tech apps, we can observe that most of them seem to have the same set of capabilities and characteristics, which include:

👉 Scalability to meet the needs of a growing workforce.
👉 High accessibility to employees, which is especially true for multinational companies with worldwide systems
👉 Low latency and the capacity to handle a large amount of traffic.
👉 Capability to gather data from a variety of sources.
👉 Integration with a variety of external systems or applications.
👉 Availability of a wide range of features

Tech Stacks: Everything You Need To Know

The kinds of programming languages and frameworks that may be appropriate for your Human Resources software are available. The tech stack you choose should be based on your specific requirements.

A lot of factors must be considered when deciding on a technological stack for web development—each component therein, and all of them combined, directly translate into the efficiency, productivity, and usability of an app.

Keep in mind that a tech stack is made up of the app’s infrastructure, whereas an app is technically made up of the backend and the frontend.

The infrastructure of the app should include:

  • A database is used to store all the data of the app
  • A caching system is used to reduce database load and assist the database in processing traffic spikes.
  • A web server is used to process requests from browsers and return data.


The purpose of a database is to locate, classify, present, and sort data in an application in response to user requests given via a Web browser. A database can also perform numerous computations to further assist user queries. Many online services, such as e-commerce websites or discussion forums, rely heavily on databases. The following types of databases exist:

    • Relational databases like MySQL, IBM DB2, Microsoft SQL Server, etc.
    • Non-relational databases like Redis, Couchbase, Apache HBase, etc.

Caching System

By serving formerly used and accessible data, the caching system lowers server latency and relieves the database of heavy demands during periods of high traffic. Web apps that don’t use a caching system are frequently slow and give poor site performance.

Memcache, Redis, Riak and Hazelcast are the most commonly used caching systems.

Web Server

A web server accepts, processes, and transmits user requests in the form of an HTML message.

The well-known website servers on the Web are Apache, IIS, and Nginx.


The frontend, also known as the client-side, is everything that a user can view. Through the physical presentation layer, the frontend enables interaction with a Web application. It includes the following:


Frameworks, which contain standardized code packages to speed up development and provide useful components, are used to build the HTML and CSS portion of the frontend. Bootstrap, Foundation, Stylus, Semantic UI, and UI Kit are popular HTML and CSS frameworks.

Frontend frameworks, such as Vue, Angular and React, are used to create the JavaScript element of the frontend, which is similar to HTML and CSS. Web developers may leverage JavaScript frameworks and libraries to make apps more interactive and improve the user experience.

The availability of information, developers, and creative solutions, as well as your business needs, all influence the frontend technology you choose. Interactivity is generally required in HR apps to increase usability and user experience. Lightweight JS technologies like Vue or React are ideal in this situation. Both offer a large number of libraries to pick from, each with a different set of UI characteristics that will make the app more user-friendly, interactive, and useful.

Another advantage of adopting solutions like React Native is the possibility to share up to 80% of the codebase, reducing software development time and expenses. Phoenix HTML with partials in React or Vue will suffice if interactive elements are used even limitedly. You don’t have to construct the frontend and backend separately with this design; you may always add more interactions as the project progresses.


The backend, also known as the server-side, is in charge of any communication between the client-side, the server-side and other components of the backend. Typically, the backend consists of server-side software and background processes.


The server-side software in a Web application architecture specifies how the server, application, database, and other components interact and function together.

The code for a web app can be built from scratch or with the help of a backend framework, which makes the development process fast. A variety of frameworks are built on top of each programming language.

Backend processes

A lot of the time, the business logic produced behind the scenes is substantial and takes a long time to process. Because current resources are essentially reserved for some other task, an application may slow down or even be halted. When the user is prepared to accept such drawbacks, such as when a large file needs to be uploaded, it’s not that awful. Yet what if someone wants to send 1000 emails from the interface with a single click of a button, but the server processing takes minutes? This is the ideal application for background processes.

This is the ideal application for background processes. It’s usual practice to delegate some of the time-consuming functionality to external workers in order to improve the user experience and the application’s performance. All the components discussed above, together, are called a technology stack.

What If You Choose The Wrong Tech Stack?

Although there is no such thing as a “wrong” technology stack, and your HR software will operate with any of them, the possibilities of each configuration have a significant influence on the development process and the business effectiveness of your app.
From a business standpoint, picking an ineffective tech stack might stifle growth, but picking the appropriate tools gives you huge benefits from the competition.

So, how do you do it? Picking the incorrect technology for a comprehensive HR app might either hamper future continuation or flexibility or be an expensive error to solve with the appropriate stack.

Scaling complicated apps to handle an ever-increasing number of users, for example, is far more difficult and costly when using verbose programming languages and a highly reliant codebase. Traffic surges and several concurrent processes may also prevent an app from providing uninterrupted services to its users, indicating a compelling need for horizontal or vertical scalability of infrastructure.

High downtime and system instability caused by bugs and crashes are further drawbacks of selecting an incorrect tech stack.To avoid these problems, pick technologies that are simple to maintain and scale, i.etechnologies that are also highly productive, requiring minimal resources to offer high speeds.

A reputable software development firm will be able to offer you the essential suggestions after analyzing your business demands. Typically, they will do discovery workshops to determine the best technical solutions and to connect your vision with their knowledge.
