Experience

Physical-based Cloth Simulation

As a part of my master's thesis, I developed an environment for simulating cloth using systems of particles and springs, implemented using Java. It uses a custom solver for differential equations and a custom implementation of collision detection and resolution to introduce interactivity. The visualization is made possible using JOGL.

Tracking

Tracking is a simple web application for tracking working hours, with multi-user support and the ability to distinguish between different user roles. The back end is based on a combination of PHP, Laravel, and MongoDB. On the other hand, the front-end is built using HTML, CSS, and JavaScript; fueled with Bootstrap and React.

Phunctional

https://github.com/Hgazibara/phunctional

I authored a small library for playing with coding projects. Creating it made it easier to apply functional programming in PHP. The library itself was inspired by Python's functional programming abilities.

Esoterics

https://github.com/Hgazibara/esoterics

The project is an ever-growing collection of Python interpreters for various esoteric programming languages. It started as a fun side project but grew into an interesting learning ground.
