Projects

QR Everything - WIP

Create REST API for generating QR codes. Idea is to use it as backend service for PWA application that will allow users to create their custom QR codes for media walls, TVs and other screens.

Technologies used are Java 14, Quarkus framework, PostgreSQL database, reactive hibernate and reactive reasteasy libraries, Testcontainers and JUnit5 for testing.
This project uses Github workflows for builds and Circleci for code quality and static code analysis.

Github repo

Chatbot - Master`s thesis

Full stack application for scheduling of office hours on University. Application integrates with Facebook Messanger to communicate with students, uses Wit.ai engine to parse inputs from chat and understands intent. Back office application is used to register professors into the system, schedule office hours and approve or deny request for meeting.

Technologies used are Java 8 with Spring Boot 1.5, PostgreSQL database with Spring-data overlay, Angular 6 and couple of more things.
