FAQ

All you need to know about custom web development services.

The first thing to consider when choosing a potential partner for your web app development is to check their tech stack, past web app projects they’ve been involved in, testimonials and reviews from past clients.

For many business people the key factor of a fruitful cooperation is trust. Search for companies and people who will not promise you things that are too good to be true, and will be honest about certain tech solutions’ constraints, as they are honest about their benefits.

An easy way to vet your web app development company and their credibility is usually a call with one of the team members, so you can ask questions,

In web development, key technologies include JavaScript and TypeScript for dynamic content and scalable applications, React for building reusable user interfaces, and Next.js for server-side rendering to enhance performance and SEO. React Testing with tools like Jest ensures component reliability. Ruby & Ruby on Rails provide a dynamic language and framework for rapid application development. Node.js is essential for server-side scripting, making web applications efficient, while NestJS, leveraging TypeScript, offers a framework for constructing scalable server-side applications. These technologies form the core toolkit for modern web development, covering both client and server-side needs.

SEO is crucial in web development as it ensures websites are discoverable by search engines, improving visibility and traffic. Effective SEO practices, including responsive design, fast loading times, and keyword optimization, enhance user experience and website ranking. Integrating SEO from the development phase helps in structuring content and coding practices that are search engine friendly, leading to better online presence and potentially higher conversion rates. Therefore, incorporating SEO strategies is essential for any website looking to achieve and maintain a competitive edge in the digital marketplace.

Web development and software development are both crucial fields in the tech industry, each with distinct focuses. Web development specializes in creating and maintaining websites and web applications, utilizing technologies like HTML, CSS, JavaScript, and frameworks such as React and Angular. It's primarily concerned with the internet and browser-based solutions. Software development, on the other hand, encompasses a broader scope, including web development but also extending to desktop applications, mobile apps, and system software. It involves programming languages like Python, Java, and C#, and requires a deeper understanding of software design, user interface, and experience across platforms and devices. Both fields require critical thinking and problem-solving skills, but they cater to different digital environments and user needs.

The completion time for a web development project varies significantly, depending on the project's scope, complexity, and specific requirements. Small projects, such as simple websites, can take a few weeks, while more complex applications, like custom web applications, may require several months to over a year. Factors influencing the timeline include the number of features, the level of customization, the technology stack used, and the team's size and expertise. Effective planning, clear communication, and agile development practices can help manage timelines efficiently. Ultimately, understanding the project's scope and setting realistic milestones are key to estimating the completion time accurately.
