💡 Summary
I am a senior majoring in Computer Science with a strong focus on front-end
development. I have a solid theoretical foundation and practical skills in building web
applications using React, Next.js, TypeScript, and Three.js. I actively use AI tools
(Claude, ChatGPT, Gemini) to optimize code writing and debugging. I understand the
principles of client-server architecture and working with REST APIs, and I have
experience with automated testing. I have a successful track record in a leadership role
in retail, where I gained skills in team management, conflict resolution, and handling
complex customer requests. I am ready to learn quickly, take on responsibility, and build
high-quality products.

💻 Pet Projects
Student PNU Web | [HTML5, CSS3, Vanilla JS]

• GitHub: https://github.com/IvanDutsak/student-pnu-web.github.io
• Description: [A standalone client-side web platform for KNU students, powered by
static JSON data without the need for a server-side component (backend). The app
provides quick access to the schedule, allows users to track changes in detail (which
classes have been added or canceled) via a special interface, includes a GPA
calculator, and lets students monitor the classes they have selected and added to
their profile.]
• What I did: [Designed a fully responsive interface with a modern light and dark theme
system, using only HTML, CSS, and Vanilla JS. Implemented complex client-side
logic for quick search and filtering of routes, comparison of schedule changes, and
configured local storage of selected data in the browser (LocalStorage) for offline
use.]

Robota Stats | [HTML5, TailwindCSS, Vanilla JS, PWA]

• GitHub: https://github.com/IvanDutsak/Robota-Stats
• Description: [An interactive web calculator and performance analytics tool for order
pickers, implemented as a PWA (Progressive Web App). The app allows users to
track hours worked, dynamically calculate pay based on different pay scales, and
monitor performance metrics for bonus calculations.]
• What I did: [I developed a modern, responsive app using TailwindCSS and
configured it as a PWA with a Service Worker, enabling users to install it on their
smartphones and use it fully offline. I wrote the payroll calculation business logic, a
metrics analytics system, and a robust state-saving mechanism in Vanilla JS.]

Cryptographic Simulator | [HTML5, CSS3, Vanilla JS]

• GitHub: https://github.com/IvanDutsak/Cryptographic-simulator
• Description: [A comprehensive interactive online learning platform for cryptography
that combines a 15-lesson theoretical course, practical online simulators, and a fully
functional cipher. The project runs entirely locally, allowing users to study and test
seven classic encryption algorithms.]
• What I did: [I built the course structure and responsive interface from scratch,
implementing lesson progress tracking via LocalStorage. I personally programmed
the logic of encryption algorithms (Caesar, Skitala, Playfer, etc.) in JavaScript, and
also developed interactive simulators with instant validation of user-entered data.]
