Some information about my projects
AI & Machine Learning
Desktop AI Companion (Electron + React)
Built a local desktop application with a 3D companion character rendered on top of the desktop. The project includes chat with a local LLM (Ollama), voice input/output, VRM avatar support, and an interactive UI.
Stack: Electron, React, Vite, TypeScript, Three.js, React Three Fiber.
… DeepSeek Desktop GUI Agent
Developed a desktop GUI for working with AI models, including session management, model parameter controls, markdown response rendering, and a tool mode for running local tasks. The interface is optimized for long work sessions and fast local model startup.
Stack: Electron, JavaScript, HTML/CSS.
Telegram Auto-Reply Bot (DeepSeek/Ollama)
Built a Telegram auto-reply bot with support for DeepSeek API and local Ollama models. Added personal/group chat modes, short-term conversation memory, customizable response style, and command-based behavior control.
Stack: Python, Telegram Bot API, OpenAI-compatible API, dotenv.
Ollama + ComfyUI Text-to-Video Bridge
Built a local bridge project for generating videos via Wan2.2/ComfyUI directly from AI chat. Implemented a proxy panel, a memory/VRAM safe mode, and a single flow: "chat -> video generation -> result".
Stack: JavaScript (Node.js), local AI services (Ollama, ComfyUI).
Ref: README.
Q-square Android Prototype
Built an Android prototype with a launcher screen and two modes: API settings and a WebView interface for media services. Implemented UI customization (tab bar, element behavior, styles) and local settings storage.
Stack: Kotlin, Android SDK, Gradle.
My portfolio also includes several small test projects for Arduino and ESP32.
One of these projects is an experimental ESP32-S3-based system focused on computer vision and HID emulation. In the test version, a local AI model analyzes the screen image in real time, detects target visual objects, and extracts their coordinates. The data is then sent to ESP32-S3, which can emulate an HID device (for example, a mouse) to demonstrate automated control.
This project was created as a technical experiment to study computer vision, real-time image processing, interaction between a local AI model and a microcontroller, and input device emulation.
Important: this solution is a test prototype and a technical demonstration. It is not intended for violating online service rules, interfering with third-party software, or gaining unfair advantages in games. Final implementation and usage depend on specific project requirements.

11 USD Simple Telegram bot
Python
You have before you a simple Telegram bot for receiving payments and communicating with clients.
The bot already has integration for cryptocurrency payments, as well as the option to connect payments via Smart Global card. It is important to note that Smart Global requires verification, and the setup of this payment method depends on your data and your readiness to go through the necessary connection steps.
… A card payment method is also available for users from Ukraine. This method works through phone number verification: the bot automatically rejects all numbers except for Ukrainian ones with the code +380. This is done to restrict access for users from "other" countries to more personal information, as card data can be considered personal information.
The bot includes feedback functionality for users. If a buyer wants to contact you regarding consultation, payment, or other questions, they can write to you directly through the bot. You will be able to respond to them directly, which is convenient if you plan to work with managers or connect to the main Telegram bot account based on artificial intelligence that will respond to potential clients on your behalf.
The bot also has a basic anti-spam system already set up. If necessary, a ban system for individual users can be additionally implemented.
The final cost of development depends on your wishes, additional features, and the overall complexity of implementing the bot.
