Software Developer

Building software across web, systems, and low-level engineering.

I’m Szymdows - a developer creating projects ranging from web applications to shells, emulators, kernels, and experimental engines.

Featured Work

Projects

A selection of projects across systems programming, low-level software, developer tooling, and web-related experimentation.

Emulation / Systems

SzymdowsVM-CPU-VM

A Python-based x86 CPU-style emulator built to explore instruction execution, assembly handling, and low-level architecture concepts.

Python x86 Concepts Assembly Emulation

View on GitHub

Built with: Python

Overview: This project is an x86 CPU-style emulator focused on instruction execution and assembly-related behavior, built to explore how lower-level systems can be interpreted and run.

What makes it interesting: It reflects systems thinking, execution flow design, and an understanding of how CPU-like behavior can be modeled in software.

Developer Tooling

SzShell

A shell written in C++ that aims to make it possible to run bash-style code and commands on Windows, helping reduce friction between Linux/macOS shell workflows and Windows environments.

C++ CMake Shell Tooling

View on GitHub

Built with: Mainly C++, with a small amount of CMake

Overview: SzShell is a work-in-progress shell that allows bash-style commands and code to be used on Windows, helping bridge an annoying workflow gap between Windows and Linux/macOS.

Current state: It is still in progress, but it does work and already demonstrates practical command-handling and shell behavior.

Web Engine / Experimental

PyWebCore

An experimental web engine built in Python that can load simple web pages, including Google, while handling unsupported content and exceptions gracefully.

Python Web Engine Parsing Rendering Concepts

View on GitHub

Built with: Python

Overview: PyWebCore is an experimental web engine created to explore page loading, parsing, rendering-like behavior, and graceful handling of unsupported content.

Current state: It can already load simple web pages, including Google, and handles things it does not understand in a stable and thoughtful way.

Kernel / Low-Level

SzymOS-kernel

A kernel written in C with some Assembly that boots using GRUB and writes directly to the screen, built as a low-level systems and OS development project. GRUB is used only for booting.

C Assembly Kernel GRUB Boot

View on GitHub

Built with: C and some Assembly

Overview: SzymOS-kernel is a low-level kernel project that boots through GRUB and writes directly to the screen, serving as an exploration of kernel and OS development.

Important note: GRUB is only used to boot the kernel. The kernel itself is your own code, not a GRUB-based system.

About

What I Build

I work across web development, systems programming, low-level software, developer tooling, and experimental projects.

Szymdows

I’m a software developer interested in both high-level and low-level programming. My work ranges from web technologies to shells, emulators, kernel development, and experimental engines.

I enjoy building software that explores how systems work internally, while also creating practical tools and web-based projects with clean structure and strong functionality.

My main languages include HTML, CSS, JavaScript, Python, C++, C, and Assembly.

Approach

I like building things that are technically interesting, useful, and deeply connected to how software works under the hood.
