I developed a command-line application that receives a command set and simulates its execution on a Turing machine. Some mathematical models can be hard to understand. This application aims to help people get a more intuitive understanding of the essence of one of the most important abstract machines in the automata theory. The application uses the Windows API to animate the work of the Turing machine directly in the CLI.

I built a tool that emulates the execution of 8086 assembly instructions. Written in pure JavaScript, this application helped me and many other people visualize the work of the Intel 8086 microprocessor to understand the impact each instruction has on the computer's inner workings. It tracks the state of the memory and registers, which can be dumped for further inspection.

A Chrome extension that adds an ability to select ASCII emoji from a list provided by the extension, which inserted it directly into Twitch.tv chat's input box. The list was scraped from a website since the owner couldn't provide me with an API, so he gave me permission.

A Chrome extension for YouTube which I wrote for myself after noticing that YouTube lacks certain functionality like showing the like/dislike bar in the search results page, hiding it on the watch page, hiding comments based on keywords specified (to hide spoilers, for example), hiding unrelated recommended videos on the watch page based on the result of the analysis of video title.

Built from scratch and using a cutting-edge permission distributed ledger framework, this application allows universities to manage and analyze their staff and students' performance. Lecturers also can track a student's academic progress. On top of that, since this information is public, employers can check if an employee's diploma is valid.

A hobby project of mine, which consists of two security measure devices specifically designed to deter people from stealing from tents when there is no one inside. One of the devices is placed inside a tent, which detects human presence using IR and microwave radar detectors and sends a signal to the second device—a receiver that notifies you if someone has entered your tent. Communication is done using LoRa technology, which allows both devices to communicate at large distances using minimal current.

Created a charade game from scratch. The development included making animations, interacting with Firebase for data storage, integrating third-party services for ads, bug tracking, and data analytics.

Technologies: React Native (Expo), Animated library, i18n, AdMob, Firebase, and Sentry.
