Electricity Auction Platform

This project involved a multinational Java and Ext JS-based platform that hosted auction processes primarily used by power plants. My primary role was to write supporting web services for logging system events and storing documents in a database. My secondary role was to optimize a core component and to create Ext JS elements for displaying old document information.

Simulation of a Smart Home
This project involved a Java and JavaFX-based desktop application for creating simulations of a smart home using rule engine EasyRules. The simulation consists of a set of appliances, sensors, set of rules and outer conditions (e.g., outer temperature, humidity, or the chances of a person entering a room). The rules dictate under which sensor states do appliances turn on or off and describe the setup of appliances. The appliances, in turn, affect the state of the virtual room (read by sensors) and create a loop. This project offers interfaces to be implemented for real appliance or sensors to be used in the future.

Project References

This project—built with Java and Spring Boot with Angular front-end —involved filtering large amounts of finished projects, creating project "baskets," and generating a portfolio of references (PDF or Word file) to apply to next similar project. JasperReports was used for generating documents. This web application also has the ability to edit project information and control concurrent editing by switching to a read mode if another user was already editing.
