Carbon accounting platform developed with React JS
Our eco app is a web platform that helps companies to track the amount of greenhouse gasses and mitigate the negative effect on the environment. This solution brings value to businesses that operate in the EU and have to comply with local regulations. Besides, eco-friendly companies have better chances of securing investments and bank loans as well
as creating a positive public image. The platform provides a convenient way to record and store all the data and generates reports that a company can share with regulators or investors. The web app applies the standards relevant to the company's country of operation, which makes the reporting process easier for the company and saves money on hiring eco specialists. Our React JS development company defined the platform's features, designed, and developed the MVP.

SEO friendly
React JS gives opportunities for enhanced Search Engine Optimization of websites and web apps because it supports Server-Side Rendering. SSR is a technology that renders app pages on the server side. This way search engines index the content quicker, which ensures better search ranking and ultimately brings more people to the web app.
Enhanced performance with virtual DOM
DOM stands for Document Object Model and it's a set of practices that structure web pages and their content. The addition of 'virtual' refers to a JavaScript object which copies the real DOM. With virtual DOM, we can save some page content to a user's browser and store it there instead of the server. This way, the browser refreshes and uploads the pages quicker and the overall app load speed increases.
Scalability opportunities
React JS has some design characteristics that help scale React JS apps easier. For example, the functional programming approach that helps store and reuse individual elements or pieces of code. React JS is also great for scaling existing apps if their stack is compatible thanks to integration abilities in its design.

Design & Development
Our design team has result-oriented experts who create engaging digital products. Implementing the latest UI trends, they don't forget about UX and users' comfort. Once the design finishes, it's time to code it. The design team works closely with the developers to transfer the designs into code effortlessly. Then the developers make it a digital reality.
React JS Consulting
Offering React JS development services, our experts don’t write code right from the start. First, we take time to analyze the future product requirements and business goals. We study the details that our clients share to come up with a logical strategy for the development process. We make the client's vision fit the budget and deadlines.
Server-Side Rendering
With React JS, we can make a server-side rendered web application. This helps to achieve better SEO rates and prioritize the app in search engines. Ideal for marketing needs, the server-side rendering feature brings value for users too. It enables the web app to load faster, regardless of the user's poor internet connection. Two birds with one React JS!
Custom Web Solutions
Template-based web solutions bring less or no value to users, with limited functions and copy-paste looks. No product can fit into a template if it offers unique and innovative features or if the product stands out from its competitors. We offer custom, made-from-scratch web solutions for businesses that aspire to win their clients' attention.
and Maintenance
TAfter the web app's launch, the work isn't over. Our team will make sure that the product works flawlessly and fix new bugs when they appear. With the post-release support and maintenance, our clients know where to fix things in case something doesn't go as planned.
React JS Migration
When technologies get old and lose developers' support, it's time to move to something popular and regularly updated. With React JS, your web app will perform better and have fewer bugs. Supported by Meta and a vast developer community, this frontend solution is a solid choice for a long run. Consider side benefits of implementing the SSR feature for SEO-optimization when choosing where to migrate.


  • Is React JS a web or a mobile coding language?

    React JS is a JavaScript library to develop web apps and sites. It's easy to be confused with React Native, which is a mobile technology. They have similar names because they 'descend' from the same programming language, JavaScript. React Native is a newer technology for developing hybrid mobile applications that work with one code base on iOS and Android platforms.

  • Do you work with other technologies rather than React JS?

    As a full-cycle development agency, we work with other technologies required to build a fully functioning product. Our standard stack for web development is React JS for frontend and Node JS for backend. We have expertise in other programming languages, libraries, and frameworks.

  • How does your agency work in terms
    of process management and payment terms?

    We assign a team to your project with a Project Manager, who is the main point of your communication with us. The Manager keeps you updated regarding the entire development process, showing results and giving details on the progress, plans, and so on. We work on Time & Material contracts, which suit best the agile development that we practice.

  • Do you offer support and maintenance
    for existing products?

    Yes, we take products on the post-release support and maintenance. We can help you scale the product and add new features. In this case, we'd ask you to share the code base to examine and offer development options based on our examination.

  • What is the typical timeframe for React JS app development?

    The timeframe depends on the app type and features it has. As our main expertise is MVP development, we can give you the statistics collected in the previous years. Usually, it takes 3 months to define, design, and develop an MVP. After this, the product is ready to launch. To get a more precise timeframe estimation, please contact us and we'll be happy to give you one.

    with you?
