FASS – Fully Automated Scheduling System based on universal polynomial time complexity the algorithm used to solve the Time Table problem for any instance.
Prototypes of solutions to the well-known hardest problems in mathematics and computer science such as Traveling salesman problems, Automated project planning, 3-SAT, etc.
MASS – Medical Administrative Software System designed to represent data that accurately captures the state of the patient at all times. It allows for an entire patient history to be viewed without the need to track down the patient’s previous medical record volume and assists in ensuring data is accurate, appropriate, and legible and makes it much more effective when extracting medical data for the examination of possible trends and long term changes in the patient (Groovy-Grails + Activiti)
Web applications using Java technologies and Database integration of Oracle, MS SQL, MySQL, MariaDB, etc.
Business Process Management systems based on jBPM and Activiti implementations with the possibility execution of business processes described in BPMN 2.0 (Business Process Model and Notation).
Reporting systems – based on JasperReports library the most popular open source reporting engine.
