University Projects — Roman Nečas

Coursework from the Bachelor of Information Technology programme at the Faculty of Information Technology, Brno University of Technology (FIT VUT), 2023–2026.

This repository is a portfolio snapshot — for each course, the version of the project that was submitted and graded. Some projects are team efforts (co-authors credited in the relevant directory); the rest are solo work.

Highlights

If you only have time to look at a few projects, start with these:

• ISA — ICMP Covert Channel (C, OpenSSL) — encrypted file transfer tunneled through ICMP Echo packets.
• IJA — Advance Wars clone (Java 21, JavaFX, 93 JUnit tests) — turn-based strategy game with two AI opponents and a replay system. Team lead.
• IIS — Winery Management System (Laravel 12, Tailwind 4, Docker) — full-stack web app with 20+ migrations and role-based access control.
• IMP — ESP32 Heart-Rate Monitor (C, ESP-IDF, FreeRTOS) — photoplethysmography with a Kalman filter, sampled at 500 Hz.
• IPK — L4 Port Scanner (C, raw sockets) — TCP/UDP scanner for IPv4 and IPv6, benchmarked against Nmap.
• INP — 8-bit CPU in VHDL — synthesisable CPU that executes a BrainFuck-like instruction set.

Year 3 (2025 / 2026)

Winter semester

ISA — Network Applications and Management File transfer through an ICMP covert channel. A C client/server that hides arbitrary files inside ICMP/ICMPv6 Echo-Request/Reply payloads, encrypts them with AES before transmission, and reassembles them on the listening side. Includes a custom on-top-of-ICMP framing protocol, a manpage, and a PDF design document.

IIS — Information Systems Winery management web application. Grape varieties, vineyard rows, harvests, wine production, purchases, events, and customer reservations. Laravel 12, Tailwind CSS 4, Vite; role-based access control via Laravel Policies; Dockerised for dev and prod.

IMP — Microprocessor and Embedded Systems ESP32 heart-rate monitor using an optical PulseSensor and an I²C OLED display. 500 Hz ADC sampling on a hardware timer, Kalman-filtered signal, threshold-crossing beat detection. Written in C on ESP-IDF v5.5.1 with FreeRTOS.

IMS — Modelling and Simulation Ski resort discrete-event simulation in C++/SIMLIB. Analyses lift capacity, queue lengths, and throughput under varying skier arrival rates. Team of 2.

IZV — Data Acquisition, Processing and Visualization Three Python assignments covering web scraping, statistical analysis of a real-world dataset, and visualization.

Summer semester

IJA — Java Programming Language Advance Wars clone in Java 21 / JavaFX. Grid-based tactical combat with terrain costs, multiple unit types, economy, two AI opponents (random and heuristic), and a step-through replay. Architecture uses MVC (engine cleanly separated from GUI), Command pattern with full undo/redo, Factory, and Observer. Dijkstra pathfinding. 93 JUnit 5 tests across 15 test classes.

ITS — Software Testing and dynamic analysis Test design exercises: BDD/Gherkin scenarios, test case documentation, and coverage reports.

Year 2 (2024 / 2025)

Winter semester

INP — Computer System Design

• Project 1: 8-bit CPU in VHDL that interprets a BrainFuck-like instruction set (synthesisable, simulated in ModelSim).
• Project 2: Vigenère cipher implemented in MIPS64 assembly.

ISS — Signals and Systems Digital signal processing assignment in Python (Jupyter notebook): spectral analysis, filtering, and frequency-domain manipulation of audio signals.

ITU — User Interface Design UI/UX project — mockup, clickable prototype, and a final documentation PDF.

IAL — Algorithms Classic data structures in C across two homework sets: linked lists, stacks, queues, binary trees (both recursive and iterative traversal), and hash tables.

Summer semester

IPK — Computer Communication and Networks

• Project 1 (OMEGA): L4 port scanner in C supporting TCP and UDP scanning over IPv4 and IPv6; evaluated against Nmap.
• Project 2 (IPK25-CHAT): Chat client implementing the IPK25-CHAT application protocol with both TCP and UDP transport variants, authentication, and channel semantics.

IPP — Principles of object-oriented programming Two-part compiler project for the SOL25 language.

• Part 1: Python 3.11 parser using the Lark library; produces an XML AST after lexical, syntactic, and static semantic analysis.
• Part 2: PHP 8 interpreter for SOL25, built object-oriented with clean Model / Expression / Statement / Values namespaces.

IDS — Database Systems Library management database in Oracle SQL. Four-part team project (ER model → relational schema → DML and queries → triggers, procedures, materialized view, analytical queries). Team of 2.

IBS — Information System Security Security assignments covering authentication, access control, and common vulnerability classes.

IZU — Fundamentals of Artificial Intelligence Four assignments on classical AI: uninformed and informed search, heuristics, and game-tree algorithms.

ITY — Typography and Publishing Five LaTeX typesetting assignments of progressively increasing complexity — from basic documents to mathematical papers and bibliographies.

Year 1 (2023 / 2024)

Winter semester

Keyfilter — C project implementing interactive prefix-based filtering over a keyword list.

Maze — C project implementing right-hand / left-hand rule maze solving on a triangular-cell maze.

IEL — Electronics for Information Technology DC / AC circuit analysis project with Dia schematics and a written report.

Summer semester

IJC — Programming in C

• Project 1: Sieve of Eratosthenes built on a custom bitset data structure, plus a no-comment preprocessor that strips C-style comments.
• Project 2: Generic hash-table library with string interning, used to implement tail and wordcount clones.

IOS — Operating Systems

• Project 1: Bash shell scripting for log processing and filesystem traversal.
• Project 2: Process synchronization in C using POSIX shared memory and semaphores.

INC — Digital Design Digital logic assignment (schematic / VHDL level).

Notes

• All projects were developed for FIT VUT courses and graded by the respective instructors. They are published here as a portfolio snapshot; the faculty's academic integrity rules apply to anyone considering reuse.
• Team projects list co-authors inside the relevant project directory (e.g., IDS/xnecasr00_xpribik00/).
• Binary build artefacts and third-party dependencies are generally excluded; follow each project's build instructions to rebuild from source.
