online tax return platform
Our team’s job was to create an application to make tax settlements easier, available in several versions: a download for computers, a convenient mobile version for mobile phones and tablets, and a version that could be used quickly and easily in any web browser. The priority was to create a cost-effective solution that would remain resilient to traffic through proper optimization. The reliability and availability of PITax.pl are particularly important in the period from March to April, a time of increased use of the service. The client’s requirement was also to implement a business rules engine that would allow easy incorporation of changes resulting from frequent tax law updates into the system.
- Simplicity of use
maximum simplification of the complex tax settlement process.
- Reliability and efficiency
as the majority of the platform’s revenue is generated during the period of increased traffic (March and April), it was crucial to make the application highly reliable, especially during increased use.
- Security at the level of online banking
to guarantee full protection of sensitive information included in the completed documents.
the architecture created was to make the portal work efficiently with the current number of users without the need to use redundant infrastructure (e.g. maintaining additional servers). The capacity of the platform was to be increased gradually — only when it becomes necessary due to the interest in the service. As a result, it was possible to reduce PITax.pl’s operating costs to the bare minimum at each stage of development.
- The solution is based on the Java programming language and its Spring and Hibernate frameworks
These are proven tools with significant technical support, enabling the development of stable and secure web applications (medium and large).
- Avra’s original idea was to implement a business rules engine based on a meta-language automatically converted to Java.
This has made it possible for the PITax.pl team to make changes in the way the amount of tax is calculated without the help of developers. This, in turn, translates into much lower service operating costs and makes it easier to maintain it — it’s enough for an employee to go through a short training module to be able to modify the tax calculation logic.
- Orbeon Forms
a solution designed to quickly and easily create forms on websites. It’s simple enough to enable even non-programmers to make modifications to the forms created. This solution is especially recommended for portals of large businesses and government organizations. Keeping in touch and working with the developers of the tool lets us shape the course of its development and take full advantage of its potential.
- Google Trusted Web Activity
by making use of this framework, an application for Android smartphones and tablets was created in just 2 weeks on the basis of the mobile version of the website.
a proven and one of the most widely used tools in the area of relational database management. It has great technical support, it’s easy to maintain, and comes with a free license.
