Custom Java Development Services

Whatever Java Allows, We Can Deliver


We employ a large Java development team that constitutes some 70% of our development force and sports a second-to-none command of the full range of Java development tools and techniques. The development experience of the majority of our Java software engineers equals 5-6 years, while several of our developers have Java development experience that exceeds the above figure by a factor of 2 or 3.

Certainly, the best proof of our company's remarkable mastery in Java is our project portfolio. It includes several large-scale, enterprise-level Java projects for US and Western-European Telco heavyweights, as well as an array of projects for Western clients in the Real Estate, eCommerce and other verticals.

Due to our involvement in the above projects, our Java development team has become conversant with using this technology to develop Billing, Ordering, Rating, Invoicing, CRM, Document Management, Time Management and other functionality.

While the bulk of our Java development experience stems from complex Telecom projects, we have also used Java to develop Enterprise software and B2B, B2C and B2E applications. Many of the Java-related tasks, solved by SYTOSS’s Java software engineers, can be rightfully referred to as ultimately challenging in Java development.

In addition to its Java development experience, the SYTOSS team has a great deal of experience in solving non-trivial tasks associated with TIBCO-enabled system integration and the related customization.

Most of our Java projects have involved using modern development practices, including Continuous Integration, Continuous Delivery and One-Button Deployment. Importantly, we have also handled quite a bit of simultaneous Production Development and Production Sustaining, the latter involving numerous on-the-fly development adjustments.

Our project portfolio includes:

Large-Scale Java Projects for Telecommunications, Real Estate, eCommerce and other verticals

We have extensive experience in developing

Enterprise-level projects as well as B2C, B2B, B2E solutions.

We use modern development practices:

Automated testing, Continuous Integration, Continuous Delivery, One-Button Deployment
