Master's Thesis

I’m working on my master’s thesis: a web app in Django, where users can upload a photo of an animal and get it classified.

Master's Thesis ML server

The FastAPI server for the Django web app with endpoint for image classification. Runs VIT model.

Animal classification app

I have created a simple multiplatform Tkinter app, mostly addressed to the wildlife biologists and ecologists.

PuppyT

I've also tried my skills at game development and created a simple game called PuppyT (for Android devices). It saves players' highscores in a database, using http requests. It was done in Defold game engine (using Lua programming language).

Laravel class registery

Laravel, TDD project I did with colleagues. Also used: Tailwind CSS, Docker, Bitbucket, JIRA.

FastAPI server SAST

SAST report on FastAPI server, running ML model. Done using SonarQube.

Postquantum KEM (cryptography)

I have implemented a simplified Kyber algorithm. It is a postquantum (resilient to quantum computers attacks) encryption method based on lattices. There are two implementations of polynomials multiplication: convolution and FFT.

Articles, Reports

Several reports I have done are available in the Articles section.

CTFs

My account on PicoCTF website. I've also participated in Advent of Code 2024, CISCO SecurityBricks - Packet Capture Analysis CTF.

Comparison and fine-tuning vision DL models

Compared models for animal images classification and fine-tuned them for polish animal species.

Engineering thesis

Analysing data from Reddit's API using ML and DL models.

Regression models

NYC cyclists data. Data cleaning (lot of time went into merging the data), EDA, analysis. Multiple and KNN regression models.

Analysing volcanoes

Data cleaning, EDA, analysis and advanced visualizations.

Simulating stocks

Simulation used Markov chain. Project was done using just Python, Pandas, PyPlot.

Analysing data from API

Main objective was downloading the data from an API and converting it to a dataframe.

Pizza shop ETL

Data warehouse created using SSIS. Data visualization in Power BI.

Analysing Iceland's spatial data

In the PDF, I've only selected the part done by me - that is Iceland. Data source: GEBCO. Data analysis and visualization was done in QGIS and ParaView.

Kriging and SGS

Project where I created kriging and SGS models to simulate air polution in Warsaw during winter time.

Smart room (IoT)

I've set up a ESP8266 NodeMCU microcontroller with temperature sensor that sends temperature and humidity data to MySQL DB via JSON request. The web app written in Python's Flask reads the data and creates visualizations (also using AJAX).

Genetic algorithm

Implemented a genetic algorithm model to solve a travelling salesman problem.

Python projects

Repository containing 3 projects written in Python. The most advanced one is "minesweeper", which uses OOP paradigms.

SHA-512 brute force

Simple Python program to break three lettered strings hashed with SHA-512.

RC4 cipher

RC4 cipher implementation. There are sample input and output files in repository.

Backtracking

Program that solves a problem in which a ship is looking for a port using backtracking.

Sorting algorithms

Compilation of several sorting algorithms.

Microscope application

Application that reads via USB data from a digital microscope. It can show the image in real time, save screenshots, edit them and add notes.

XML parsing

Program that reads a XML file with geospatial data points, lines and surfaces.

Online game

Online 2-player (using sockets) game where you have to pick more mushrooms than your opponent.
