GPT simulator for preparation for oral interview in English (B2)
AI & Machine Learning
Developed a custom training system based on GPT for preparation for an oral interview in English (B2 level).
The goal was to transform a regular chatbot into a structured training tool with clear learning logic that simulates the real process of preparing for an exam or interview.
… The system has the following functionality:
• step-by-step training (2 sentences at a time to reduce overload)
• several modes of operation:
• training (controlled format)
• topic repetition (recall)
• full review of the topic
• interview simulation
• management through commands (like a mini-interface)
• progress display (topics and steps)
• pronunciation training with feedback
• evaluation of answers in the format of a real interview
• adaptation to the user's field (full personalization to your interests and area of activity)
The system helps:
• reduce the fear of speaking English
• develop an active vocabulary
• learn to logically construct answers
• prepare for a real oral exam
The project demonstrates how GPT can be used not as a chat but as a full-fledged educational tool with logic, structure, and user control.

A system has been developed for the automatic collection, merging, and deduplication of publicly tagged cryptocurrency wallets from centralized exchanges (CEX) in the Ethereum, Arbitrum, Optimism, Base, zkSync, and Polygon networks. The system retrieves data from official APIs and open blockchain explorers, forming a clean, structured database of addresses for further analytics.
Results:
• Over 2.4 million rows of data collected from open sources.
… • After filtering and removing duplicates — 1.42 million unique addresses from centralized exchanges.
• Data is exported in .csv and .xlsx formats for further use in analytical systems.
Technologies:
Python (asyncio, aiohttp), Dune API, CSV/Excel aggregation, AWK, Pandas, automatic recovery from API limits, logging, and processing large volumes of data.
Implementation features:
• Automated data collection from multiple sources.
• Parallel processing of large volumes (2+ million rows).
• Algorithmic deduplication and normalization of tags (Deposit, Custody, SmartWallet).
• Readiness for integration with analytical or graph systems.

TG Inbox — centralized processing system for Telegram messages
Python
Project: development of a CRM system for managing incoming messages from dozens of Telegram accounts in a single web interface.
Technologies: Python (FastAPI, SQLAlchemy, Telethon), PostgreSQL, HTML/JS, Tailwind, Telegram Bot API, Linux.
⸻
…
Project Goal
To automate the work of recruiters and operators by consolidating all Telegram messages into one system. To ensure quick responses, control the status of dialogues, and notify the team about new messages.
⸻
Main Functionality
1. Inbox (central panel)
• Display of dialogues in real-time.
• Automatic statuses.
• Filters by recruiter, Telegram account, status, or time.
2. Access system
• User roles: admin, recruiter, viewer.
• Recruiters see only their dialogues.
• If an account is unassigned, its dialogues are accessible to all recruiters in the category.
• The administrator has full access.
3. Message template module
• Creation, editing, and deletion of templates.
• Integration with Inbox — the ability to quickly insert a template when responding.
• Support for personal and global templates.
4. Telegram notifications
• An integrated Telegram bot sends messages to the group for each new incoming request.
• The message text and username are transmitted automatically.
5. Workers and multithreading
• Separate asynchronous worker for each Telegram account.
• Queue manager (Outbox Dispatcher) for sending without blocking.
• Automatic media saving and session status monitoring.
⸻
Result
A fully automated system has been created that:
• Collects all Telegram messages in a single interface;

334 USD Automated data collection through multi-level OSINT parsing
Databases & SQL
As part of its own OSINT toolkit, a script has been implemented that automatically processes a database of over 6000 organizations and searches for each one:
• email,
• phone,
• official website,
… • full name of the head,
• public utility/company.
To achieve the result, several sequential parsing stages were used:
1. Clarity-Project.info — automatic extraction of email, phone, and full name of the manager from the Unified State Register of Enterprises and Organizations (EDRPOU).
2. DuckDuckGo Search + Google Search — forming a query like Name + email + phone, with parsing snippets from the first 10 results.
3. Proxy rotation (http/socks5) to bypass anti-bot protection.
4. Automatic saving of results to a .csv file after each successful request, with progress logging (for example: [959/1004] name (identifier) → Email: | Phone: ).
5. Final processing in Excel: merging address, email, and phone into one column using the formula =TEXTJOIN(", "; TRUE; F2:H2).
Technologies:
• Python (requests, BeautifulSoup, fake_useragent)
• Proxy rotation
• Google & DuckDuckGo search scraping
• CSV/Excel processing (pandas, openpyxl)
Result:
A table with hundreds of accurate contacts of organizations, supplemented with incomplete data, significantly increasing the coverage of the database for further purposes (email distribution, calling, etc.).

89 USD OF Tweaker — Earnings “All-Time” Lite
Javascript and Typescript
This is a lightweight user script that automates the display of income statistics in the section OF → Earnings → All Time. The script replaces the data in the table, allowing users to input their own gross values for each category (subscriptions, tips, posts, referrals, etc.), automatically calculates net income (−20%), and synchronously updates the interface.
All configuration is stored in localStorage, and changes are applied without reloading the page. The interface is integrated into a custom tab of the OF Tweaker panel with fields for editing and an "Apply" button.
… Main functionality
• Automatic processing of the "All Time" block in OF statistics.
• Input of custom amounts for categories (Subscribes, Tips, Messages, Posts, Referrals, Calls).
• Automatic calculation of net profit (−20% from gross).
• Instant DOM update without reloading the page.
• Parameter storage in localStorage (data is saved after updates).
• Integrated All-Time tab in the Tweaker panel.
• Safe DOM operations, compatibility with other addons (safe mode).
Key technical solutions
• MutationObserver for tracking dynamic changes in the DOM.
• Debounce for optimizing updates.
• State system via localStorage with auto-synchronization.
• Fully safe integration into the OF Tweaker ecosystem without modifying the chart.
Result
The script significantly simplifies manual data configuration in the statistics section, allowing OF creators to see their own financial models without interfering with server data or API. The interface is intuitive, does not affect page stability, and supports real-time updates.

Final design of the book cover "The Chosen Ones: Keepers of Light" (print + Kindle)
Unfortunately, the collaboration experience turned out to be unsuccessful.
The project was supposed to be completed in 7 days, although I believe it is a 2-3 day job, but during this time I did not receive a quality result.
Clear instructions were ignored: the quote is missing, the author's text contains errors, the logo was not placed, the photograph was inserted unprocessed, simply terrible, the cover style is outdated and does not match the content of the book. I did not feel any designer atmosphere, everything was done with AI and very poorly.
The cover of my book, into which I poured my soul, should be the face that immediately makes you fall in love, not run away screaming.
I provided all necessary materials in advance, but none of the important elements were properly executed.
The project had to be completed without payment.
I hope the freelancer will take these comments into account in the future.

THE FREELANCER DELAYED THE DEADLINES AND DID NOT COMPLETE THE WORK PROPERLY.
The project was closed. Because there is no time to explain and sort things out.
Promised to finish earlier than 5 days. It turned out that after 5 days, he hadn't even completed half of the task. After 8 days, he only completed the first part.
The task was to process photos of 5 people. I sent 5 photos of people that needed to be processed. For some reason, the freelancer decided to replace one of my photos with another person.
2) The task was to find other filters and process them in the same way. 5 people.
The theme was family photos, wedding, romance.
The freelancer just took one photo of some guy and that was it. He didn't do 5 people, didn't do family photos, didn't do romantic photos. Did nothing.
I am not satisfied with the work. I do not recommend. The person is irresponsible towards work and deadlines.
