The cost is never fixed when it comes to custom software application development. It is dependent on many contributing factors such as:

• Technology stack
• Project requirements and timeline
• Resources needed and their location

You can find a partner for your web solution by looking at ranking sites like Clutch. They offer a review-based rating system and short profiling so you can quickly find a top web development company.

Foremost, professional web development services should be backed by years of experience (look for companies with expertise in web development for at least 9 years) and knowledge of the wide range of technologies required to create a reliable and durable solution.

When choosing a web development agency, find out which companies they have worked with and study their case studies. A detailed review of your potential partner's website is a great way to evaluate what they can do for you.

Our experience as a web application development service provider shows it takes over 4 months to create a client application and server infrastructure. If the scope is pretty big, it may take longer. But if the web development team uses ready-made modules, we can complete the project in 3.5 months.

Relevant is one of the leading software development companies. Our engineers are fluent in English and use Slack and Google Meet to communicate between themselves and clients. We use Jira and Agile methodologies for project management, so you can easily track progress.

As a custom software development company, we provide maintenance, updates, and support services for all types of applications.

If you have an idea but are unsure of the project requirements and scope, we can discover it and validate your concept. We start with detailed research, identify your target audience and business environment, conduct competitor analysis, determine the initial scope and technical requirements, and create a hypothesis for your concept.

Now that we have a hypothesis, we start prototyping your idea. It will help you test your hypothesis, define your scope, and flesh out your idea.

Finally, depending on the project's scope - if we can freeze all requirements, we use waterfall development, and if the initial scope is clear but needs further improvements and changes - we use the Agile model.

We follow industry-standard security practices for all of our web applications to ensure the best level of security. We adhere to methods to prevent critical security flaws, such as:

• SSL (HTTPS) for security session IDs and cookies.
• Data validation through an HTTP request to prevent attacks such as SQL injection, log injection, Cross-Site Scripting, and HTTP Response Splitting.
• Server-side data validation as it is subjected to being modified.
• Frequent vulnerability scans during production and update.

If the project needs added security, we provide on-demand third-party audits and comply with OWASP for web applications and PCI requirements for eCommerce solutions.

Countless parameters must be considered, so we analyze and drill down through your project at micro-levels to select optimal technology. We think about security, time to market, scalability, maintainability, cost, the application's performance, database structure (relational/non-relational, graph database), ecosystem, and more.
