Hi, I'm Veronika 👋

I'm a Computer Science student at Taras Shevchenko National University of Kyiv.

I like building practical tools across software, automation, business processes and applied computer science. My projects range from business diagnostic systems and AI workflows to Java desktop applications, embedded control systems and UX/UI design.

Projects

Velar Diagnostic App

A Python/Streamlit prototype for structured business diagnostics.

It turns a diagnostic playbook into a workflow for reviewing business problems, collecting evidence, prioritizing findings and generating an audit report.

View project

Monte Carlo π Visualizer

A JavaFX desktop application that visualizes the Monte Carlo method for estimating π.

The project combines probabilistic modelling, object-oriented design, interactive visualization and manual software testing.

View project

8051 Vehicle Lift Control System

An embedded control-system project for a simulated two-floor vehicle lift.

The controller is implemented in MCS-51 Assembly for the Intel 80C51 and includes sensor processing, movement logic and emergency handling.

AI Virtual Administrator

An n8n-based Telegram assistant for a beauty salon with text and voice processing, AI responses and human handoff.

View project

AI Lead Response Automation

An n8n workflow for processing incoming leads, assigning priority and preparing a suggested response for a manager.
