I'm a data analyst with engineering background, currently studying cybersecurity. I specialize in Python, SQL, ML. My portfolio includes analytical, ML and apps development projects.
Engineering thesis
Analysing data from Reddit's API using ML and DL models.
Azure server administration
I've set up a MS Azure server, created basic firewall with iptables and made this server a proxy with TOR and Pi-hole. Later on I've created a reporting tool, that generated statistics regarding attempts to break into the server.
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.
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.
Website for students 2
Web application for me and my students. It's a faster substitute to Librus class register. Implemented cookie/session autherization, data is stored in MySQL
NGO website
Project I did with my brother. Here also we didn't use any frameworks. One thing that's different to other projects is the use of AJAX, so that it's a SPA.
Laravel class registery
Laravel, TDD project I did with colleagues. Also used: Tailwind CSS, Docker, Bitbucket, JIRA.
Website for students
Simple web application for my students, so they can train multiplication, browse classes' notes or contact me. It uses simple html, css, php, MySql (PDO).
Azure server administration
I've set up a MS Azure server, created basic firewall with iptables and made this server a proxy with TOR and Pi-hole. Later on I've created a reporting tool, that generated statistics regarding attempts to break into the server.
Flutter project
Created an app in Flutter, with Firebase backend. Using JIRA and Bitbucket
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).
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).
CTFs
My account on PicoCTF website. I've also participated in Advent of Code 2024, CISCO SecurityBricks - Packet Capture Analysis CTF.
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.
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.
Worked in a group on a shopping mall chatbot. Used Llama LLM with Python. I was researching methods for face-swapping, using Stable Diffusion.
Created a couple of guides on how to install, for instance, WordPress, Hugo, Next.js, on user’s VPS. Did migrations between databases. Helped clients with installations, setting up domains, etc.
I was helping in various tasks around the facility. I was getting to know different departments and how they operate.

Average grade: 4.54
Report of memory snapshot analysis, using Volatility.
A presentation on how do cheats and anti-cheats work in online games.
A presentation on Industroyer malware.
My engineering thesis. Developed a couple of AI models to detect depressive state, based on text.

High school mathematics.
I was teaching 7th grade physics and 3D printing/design (kids aged 6-12).
Mathematics tutoring. Preparing students for the exams.
Taught students aged 10-18 cybersecurity and programming: Python, C# (Unity), C++, Scratch, web development.
