Accelerate your business with custom software

Custom software development for companies of any size

Enterprise software development

The main business of big enterprises is often quite far from technology and custom programming services. In addition, it can relate to several industries, which makes it hard to find ready solutions that can be used without any customizations. That’s why we start every engagement with enterprise clients by understanding their business and defining their specific needs to solve them with custom software development solutions.

We work hard to precisely match technologies to your needs. You’ll clearly see the correlation between resources spent on IT and the impact on your core business. We’ll advise you on the best tech stack or platform to optimize and streamline the custom software development process. Our technological guidance for enterprises is your ticket to hassle-free digital transformation, which inevitably is overtaking the enterprise sector.

Midsize businesses and products

After your software product has paid off and is loved by loyal users, your next step is to ensure round-the-clock performance. Adding new features may lead to product complexity, while a growing user base can overload the system. We’re all in to support you at this stage. Our custom software programming and infrastructure management practices will keep your product up and running and overcome bottlenecks.

Using our custom software application development services, you can focus on your market and users while we cover all the engineering, testing, and maintenance work.

At Intellias, we work with custom programming projects of any size, scale, and complexity. We pick the cooperation model that’s most suitable depending on a client’s previous experience and needs as well as the project’s complexity: dedicated development team, managed delivery, or product development. Each of these models covers a different set of needs and entails a different way in which our experts engage in developing custom-built software — performing exclusively engineering tasks; managing a full range of engineering projects, supervised teams, or programs; or developing a holistic product from the initial idea stage through bringing it to the market.
Intellias will establish a successful framework for remote communication between your in-house team and your remote Intellias team at the start of your custom application development project.
