About me

Hi! Thanks for checking out my portfolio. This is mainly intended to show some of my work and serve as a digital copy of my CV.

For some background information, my curiosity for programming started shortly after I received my first computer at the age of 8. In those times, I lived in Poland’s countryside, which made this a very exciting development. My newfound access to the internet inevitably led me to gaming, which then resulted in development of basic programs using Windows Forms (I wouldn’t recommend it).

Following my families’ move to the UK, I pursued Computer Science at the University of Liverpool, where I obtained a BSc and MSc in the subject. This allowed me to begin my career in Software Development.

Currently learning

I’m excited to see emerging technologies and am keen to learn. Currently, I’m working on a few Go projects. I will add links to each of them once they’re hosted somewhere!

Prior Projects

Creating performant static websites using Hugo.io

• To learn more about Go templates, I developed a new website for a family member to replace their ancient wordpress-based site. This reduced their costs from ~£180 per year to £0.

Single-Page Application using Go and HTMX

• Developed and deployed a small single-page web app using Golang to serve an HTMX frontend, aimed at generating tailored interview questions using OpenAI models.

Full-Stack Machine Learning Application using Python (FastAPI), React, JS

• Designed and implemented a full-stack application to extract aspect-based sentiment from Amazon product reviews, utilizing pre-trained BERT and RoBERTa models.

Subreddit Classification using NLP & ML

• A Python machine learning project to predict the best-fitting subreddit for given text inputs, using abstract data models.

Bot Software

• Developed Python-based automation for an anti-bot-protected website using the Playwright library, integrating HTTP proxies, caching, and obfuscating code for efficiency and security.
