I'm a software engineer focused on creating clean, maintainable and high-performance applications using the .NET ecosystem. I enjoy designing solutions that solve real-world problems, automate repetitive work, and improve developer experience.

Outside of my professional work, I build hobby projects that help me learn new technologies while making day-to-day IT work easier.

Check out the Demo app
A fan made milanote free and self hosted alternative. Most of the code is generated by AI.

Design was created in figma until good enough version, then I manually changed a few things and fixed
what figma AI couldn't fix. Then used Claude AI to refactor some code, implement bigger functions and also
some manual work to fix few things that AI couldn't.

This application is free and self hosted alternative to milanote, Im creating this more like for fun to see
how much work will it take and how hard is it to create such advanced and complex frontend application.

There are not so much functionallities, its simple, you have unlimited projects/boards with really big canvas.
You can freely create blocks and set them like you want, you have to use checklists, notes, customizable kanbans,
images/stickers, links, columns, groups, arrows, many colors and top strip colors.

A simple IT tool for windows machines to scan, analyze and check basic vulnerabilities of the system.

• Many analyzers like performance, OS, security, windows defender and update, disks
• CLI tool
• Auto generating .html report file with summaries, stats etc.

I regularly build small utilities and automation projects that improve everyday development and IT administration workflows.

• Reverse Engineering
• Cybersecurity
• Software Architecture
• High-performance .NET applications
