contact usWe are official partners of Babel Street as a Rosette API system integrator. The company is the developer of one of the most advanced text analytics platforms available worldwide. The platform supports over 50 languages. In addition, we also undertake software development tasks for them, with more than half of the team working on the development of their new product currently under construction coming from our company. Furthermore, we are involved in software development tasks for them, participating in the development and testing of several of their products.
QA from the very beginning
Software testing is a way to assess the quality of the software and to reduce the risk of software failure in operation. A common misperception of testing is that it only consists of running tests, i.e., executing the software and checking the results - but it means much more!
Professional support from day 1
We start Quality Assurance activity in the specification writing phase by reviewing and giving feedback to the editor of the functional specification. Our Senior developers, Testers and Software Architects provide their input in terms of planning and their suggestions.
We prefer to jump in even earlier stages with experienced Business Analysts who can help the client define business ideas in the form of a software solution. Thus the expensive dead ends are avoidable.

The objectives of testing may include
- To prevent defects by evaluating work products such as requirements, user stories, design, and code.
- To verify whether all specified requirements have been fulfilled.
- To check whether the test object is complete and validate if it works as the users and other stakeholders expect.
- To build confidence in the level of quality of the test object.
- To find defects and failures by reducing the level of risk of inadequate software quality.
- To provide sufficient information to stakeholders to allow them to make informed decisions, especially regarding
the level of quality of the test object.
- To comply with contractual, legal, or regulatory requirements or standards like Web Content Accessibility Guidelines or EN 301 549, and to verify the test object’s compliance with such requirements or standards.
Quick iterations
We primarily follow an Agile software development methodology, typically with two-week Sprints, which enables the formulation and achievement of efficient sprint goals, as well as adds flexibility to change management. We support rapid testing cycles of the current version of the software with continuous integration methods.
Several of our staff members have Scrum Master qualification (Professional Scrum Master – PSM I).
The continuous release of software versions enables rapid testing cycles.
As a result, the client is able to try out the system in its current state from the very beginning of the development.

Full transparency
Cloud based task management and the reporting tool (Jira) provides a full view of the hours spent on tasks in the given development cycle. It solves the joint editing of the Backlog, as well. The test cases and the results of their runs are also transparent to our customers (we use TestLink software). This enables them to feel like we are part of the internal team throughout the software development process.
Future-proof solutions
Our experienced test engineers automate the test run (with our own, state-of-the-art, Cypress-based solution) for the test cases of stable functions. This way, it is possible to implement new functions under stable operation of previous functionality. Several members of the QA team are ISTQB Certified Testers.
Professional indemnity insurance
The safety of our projects are guaranteed by our expertise and outstanding quality assurance method. Since 2020 it is also supplemented by a professional indemnity insurance of £1 million.
Long term maintainability
In our development processes, we use modern, standard solutions that give our customers the freedom to further extend the software.
Improvability
We are experts at preparing improvable software. The key to facilitating the integration of future changes is that we pay careful attention to software architecture and quality from the outset of the project.
This allows adding new features to the software in every phase easily and sustainably.

Flexibility
Our experienced architects plan the system in a modular structure and, by using a code review mechanism, keep the functionality in the appropriate software layers (generally following the MVC model). In case of restructuring becomes necessary, we achieve it through code and modul refactoring.
This way, changes only required at the relevant modules of the software, and even connecting new ones can be easily accomplished.

Code quality
Code analysis is automatically run both on the Frontend and Backend codebases. The result is then used to improve code quality in daily development. We keep Unit test coverage of common components on high level.
Getting code quality right from the very beginning means quicker, easier changes in the future and lower overall costs.

Extensive experience
We have been expert providers of enterprise Java solutions (Java Enterprise Edition) since 2002. We have many decades of combined experience in Java and Typescript based development. A team of nearly 50 System Architects, Developers and Testers is at our customers’ disposal to solve business and IT challenges. Should the development of a complete solution require specialized knowledge, our extensive network allows us to readily engage additional experts. This guarantees that the developed solution is implemented with the utmost expertise in every aspect.
Up-to-date technologies
By keeping track of the advancements and latest achievements in the utilized technologies, as well as employing the most modern work methods, our team is capable of delivering solutions of varying complexities and up-to-date standards.
Continuous professional development is key to our success.
We organize regional professional meetups and our staff share new knowledge through in-house presentations, which are followed up through technology conference series and professional articles.
Comprehensive service
Precognox offers full-cycle development services. We build reliable, scalable and secure software applications that meet the most sophisticated requirements so that our clients can concentrate on their own business.
In case the development of the complete solution requires some unique knowledge, thanks to our wide network of contacts, we are able to involve additional specialists at any time. In this manner, it is guaranteed that the developed solution will be implemented by the highest level of expertise.
