Automated UI tests with TestCafe (REALTECH)

Testcafe is an open-source Node.js tool designed for automated end-to-end web testing. For the purpose of Smart Change Integration test, I have created not only the tests (running on 3 different ITSM instances), but also an automated workflow sending the test results from Github to Azure Node app that saves the results to a database, sends a Teams notification with topline and creates Jira issues assigning them to the responsible developers (notifying them also with an email). On top of it, app's url displays a Dashboard with graphical representation of the last and historical results along with lists of errors and tests that frequently fail.

OpenAI implementation

Backend implementation of an AI chatbot for my portfolio, built with Node.js and Express to handle communication with the OpenAI API. The chatbot processes user queries using curated materials such as my portfolio and CV, ensuring context-relevant responses. The backend manages request routing, error handling, and data parsing while maintaining efficient interaction with the frontend, which displays chatbot responses in real time. The queries and answers are stored in a database (Cloud Firestore), using a TF-IDF & cosine similarity (to prevent doubling queries) and will be used for model fine-tunning.

Vanilla JavaScript Menu

A simple menu, usually taken from some existing library, but I have built it from scratch using only vanilla JavaScript, HTML and CSS:

• opens when clicking on the element
• switches between the submenus
• second click on the currently opened item closes the menu
• "Esc" and a click outside the menu closes the entire menu
• responsive - from 500px changes to hamburger with the same functionality for submenus
• menu items and menus can be added or removed in HTML only (with proper classes) without the need to adjust JavaScript
