SUMMARY
Software Developer | Intelligent Systems Student
Experienced in Python and C, specializing in backend architecture and system design. Proven
track record of building complete web ecosystems from scratch and developing low-level modular
engines. Certified in Docker and SQL, with a strong focus on scalability, containerization, and the
integration of intelligent algorithms into modern software workflows.
EDUCATION
B.S., Intelligent Systems (in progress) 2024– 2027
Technical University of Košice

PROJECTS
2025
Microblog Web Application| Python, Flask, Docker, SQL
• Implemented user authentication (registration, login, password reset via email).
• Designed relational database models for users, posts, followers, and relationships .
• Built follow/unfollow system with personalized user feed. Implemented full-text search
functionality.
• Created RESTful routes with Blueprints and modular project structure.
• Containerized the application using Docker.
Public Transport Delay Analysis System | Python, Data Processing, CSV 2025
• Engineered a data analysis tool to process monthly train schedules and delay records from CSV
files, calculating average delays per line and per city.
• Implemented custom algorithms to parse complex timetable structures, calculate arrival times
based on travel duration and stops, and generate chronologically sorted city departure timetables.
• Successfully identified the least reliable train lines and most delay-prone cities by analyzing large
datasets with Python's core data structures (lists, tuples, dictionaries).
Company-Project Management Simulation (OOP Design)| Python, OOP 2025
• Designed and implemented a comprehensive object-oriented model simulating a software
company's operations, including employees (Managers, Developers, Testers), clients (Orders), and
projects.
• Developed multiple project selection strategies (e.g., Greedy, Random, Cheapest Employee) by
implementing a flexible Scheduler hierarchy, showcasing polymorphism and inheritance.
• Modeled complex business logic such as employee workload calculation, project profitability
analysis (income vs. wages), and resource availability checks, demonstrating advanced class
composition and interaction.
Information Spread Simulation (Random Walk) | Python, OOP, Simulation 2025
• Built a discrete-time simulation engine to model how news articles spread through a population,
utilizing Random Walk principles to analyze content reach and decay.
• Created an object-oriented model with News, Person, and Population classes, implementing
features like content categories, reader interest profiles, "surprise" decay rates, and friendship
networks.
• Simulated the dynamics of information propagation, tracking reader counts over time and filtering
obsolete content, which provided insights into optimal content structuring for maximum
engagement.
