    Consistent Branding


    Lightning Fast Loading Speed


    Search Engine Friendly Pages


    Prominent Call to Action


    Documenting the Code


    Maintaining a Coding Standard


    Meaningful Variable & Function Names


    Say No to Use Functions inside Loops


    Mobile Responsive Application


    Maintaining a Security Standard


    Building Progressive Web Apps

    Keeping the brand essence consistent is one of the fundamental requirements while creating a website. Whether it is for B2C and B2B websites, we keep the predominant icon, color, and verbiage on every page intact. This also applies to images, iconography, typography, and videos. We tell every brand story keeping its actual ‘story’ alive.

    We understand how crucial first impressions are for you. Users don’t want to wait for more than 3 seconds. So, our team ensures your web app loads within that. To make that a reality, we use CDN to load static contents (CSS, JS, and images), and Gzip to compress HTML. Also, we avoid non-passive event listeners, and execute event listeners without time-out settings, and enable caching on databases like Memcached, Redis, or cache the HTML using Varnish.

    Why make a website if it doesn’t show up on Google? Your page must be search engine friendly, to ensure your website comes up in the top results for your business keywords. Here, we make sure the page structure is on par with the Google SEO guidelines and can be enhanced upon to increase Google rankings. As a responsible web application development company, we ensure this happens with every project.

    To engage your users and take them to relevant information, we use effective and distinguishable CTAs. Since we understand the fine line of difference between a subtle and provoking CTAs, we design and implement the CTAs that essentially engage users and convert them into being a new client.

    Web apllication development process

    It is one of the most crucial practices that we follow diligently - maintaining and documenting the codebase. This helps our development team to understand it. Also, it becomes easy to review and edit them in the future. For all the custom web app development projects, we keep the documentation right.

    To maintain a coding standard is one of the defining criteria of a development team. It makes sure the code is manageable by every programmer working on it. In turn, it never stops your development work. We deliver custom web application development services where the codebase is standard, understandable, and clean.

    Web app development variables

    There has to be a naming standard for all the variables and function names. Without this, it gets difficult for other programmers and testing teams to understand the code. So, we have trained our developers to use grammatically sensible, meaningful, and correct names for every function and variable they use. This sits in agreement with the coding standard that we maintain. The result? A clean output.

    If you take the burden of storing the value returned by the function in a separate variable before the loop, then you would be saving enough execution time as in the first case the function will be called and executed every time the loop runs which can increase the time complexity of the program for large loops.

    Mobile responsive web application

    Today, more than 4.68 billion people are using smartphones. So, you cannot ignore the user base. Hence, we ensure the web application we design and develop is mobile-friendly, keeping the UX human-centered. The result? Your users are glued to your app even when they are not using their laptops.

    Web app security measures

    Enterprise or SMBs, none can improve the website’s UX ignoring the privacy and security issues. The web application must have the latest encryption mechanism to keep the corporate as well as user data secured. Hence, by eliminating the security vulnerabilities and safeguarding it from security attacks and keeping the data safe, we design and deploy every application without fail.

    Progressive web app development

    Progressive Web Apps (PWA) are the bridge between native mobile apps and web applications. It is the new generation applications that are developed using technologies like HTML5, JavaScript, and CSS3. However, it performs like a native app with a personalized user experience. Since a lot of enterprises are opting for PWAs, we are taking advantage of creating seamless user experience across all devices with PWAs.
