PROJECTS

FSA Assignment Management System — Bachelor Thesis Project
Python · ANTLR4 · Selenium · pytest
Automated grading pipeline for university automata theory assignments. Generates personalised DFA/NFA quiz
questions, downloads submissions from Moodle via Selenium, and evaluates them through structural (graph
isomorphism) and behavioural (test word acceptance) checks. Includes an ANTLR4-based DSL parser for FSA
specifications, AST-level static analysis of student code, and threaded sandboxing to handle infinite loops.

Zbojnícka Chata — Mountain Hut Website | Personal Project
React · React Router · styled-components · Framer Motion · JavaScript · Git
Developed a responsive website for a Slovak mountain hut, featuring a multi-step booking flow with an interactive
date range calendar and guest selector. Built with React 19, React Router v7, and styled-components with a
centralized theme system. Used Framer Motion for animations and Lucide React for iconography. The UI scales
proportionally from a 1920px base design to all viewport sizes via a CSS transform approach.

Discussion Boards — Forum Web Application | Personal Project
Python · Django · PostgreSQL · Django REST Framework · Bootstrap 5 · Docker · GitHub Actions · Ruff
Built a forum application with a Board → Topic → Post hierarchy, custom AbstractUser with email-activation flow, and
queryset-level ownership checks. Optimised database access with select_related/prefetch_related, Count annotations
to avoid N+1 queries, and a race-safe view counter via Django's F() expressions. Post content is Markdown-rendered

and bleach-sanitised against XSS; includes a read-only DRF REST API, full-text search via Q objects, Docker
Compose with PostgreSQL 16, and a GitHub Actions CI pipeline with Ruff and 108 automated tests.
