What Web App Development Services Do We Offer?

We are experts in custom web application development for businesses of all sizes. Here are types
of solutions we can build for you:

Custom web application development


For over a decade, our company has provided professional web application development services focusing on building custom web apps from scratch.

We have extensive experience creating:

  • Custom CRMs that optimize company processes, reduce manual work, and allow our clients to quickly reach and exceed their goals.
  • Custom ERP solutions that automate work and synchronize data of multiple departments.
  • Industry-specific web applications for Healthcare, eCommerce, Education, and Real Estate. Our solutions meet the exact needs of businesses, taking into account the peculiarities of narrow specializations.

Mobile web application development

At Greenice, we specialize in cross-platform mobile app development. Progressive Web Apps (PWA) and Hybrids (React Native) are less expensive and much quicker to develop than native iOS and Android apps. We have developed over 40 different apps for Entertainment, Education, Events, and eCommerce purposes. Among our clients, you can find Inc.500 companies as well as top U.S. pharmaceutical companies.

Our solutions are swift and powerful. They are nearly indistinguishable in appearance from native apps. They are able to work under high loads, processing hundreds of concurrent connections, which is especially important for apps that need to update in real-time.

SPA development


Need a dynamic and highly interactive app?

Single-Page Application (SPA) is perfect for news apps, maps, dashboards, event apps, online polls, social media, and other apps whose content must be updated independent of an Internet connection.

We create SPAs that have great speed and performance and work with all browsers and devices. The rapid content loading will improve your mobile users’ experience.

Being cheaper and quicker in development, an SPA is perfect for MVP projects, and when you are ready, they can be modified into native mobile apps by using the same back-end code.

SaaS development

Our team provides a full range of SaaS development services — from research and requirements identification to launch and maintenance.

We are familiar with the peculiarities of SaaS development, so we are able to create secure, customizable, and reliable systems:

  • We apply the latest and the most reliable cloud technologies (like AWS and Google Cloud) that allow us to securely store databases of different SaaS users (organizations or individuals) and deliver timely system updates.
  • We integrate different payment methods to automatically collect SaaS subscription fees.
  • Our broad experience in API development allows us to integrate your SaaS app with different third-party applications.
  • We keep an eye on all the latest data security regulations (like GDPR, HIPAA), making sure your solution is compliant with all of them.

Our team has successfully built and delivered SaaS applications for different business domains and is ready to do an excellent job for you, too.

Legacy Software Modernization


Sometimes it is impossible to add new features or integrations with third-party software if your application uses old technology. We have vast experience in legacy software modernization, helping our clients improve their systems.

With code refactoring and migration to newer frameworks, our clients obtain lots of benefits:

  • Easier and quicker implementation of new features
  • Avoiding incompatibility issues between old and new technologies
  • Significant performance and security improvement
  • Elimination of defects

Don’t worry, your data will be safe and sound, and your app will be usable during development. If you have an application that needs modernization, we can help!

The Development Team Lead will write a detailed plan that describes the technology choice and development stages, sets the priorities and timeframes, and lists responsibilities.

We will use this information to give you accurate time and budget estimates.

We assign a Project Manager who helps you divide features into sprints, supervises the development process, and reports to you on a regular basis.

We work by Agile methodology that gives flexibility to make changes on the go. First, we deliver your MVP to launch as quickly as possible and then we add the advanced features by iterations.

Quality Assurance

During the final steps of development, we bring on a team of QA engineers to make sure the product meets the requirements.

Before we certify the excellence of the product, we go through all possible user scenarios in an effort to eliminate any bugs or inconsistencies.

Deployment and maintenance

When the solution is ready, we deploy the web app online, make it available for your corporate use, or submit your app to the App Store or Google Play Store.

At this stage, we can either finish our partnership or continue to provide maintenance and future upgrades.


The technology stack we use includes, but is not limited to:
