CV
🐍 7 years in Python development — from Flask and Django to FastAPI and cloud architectures on GCP and AWS.
I've built 4 unique bots (Telegram + Discord). Each one has its own custom business logic — not off-the-shelf templates.
📊 Key highlights:
• @free_secret_santa_bot — comfy bot for Secret Santa events that has 30 000+ active participants globally 🌍
• @hobby_monster_bot — Telegram bot for events in a board game club in Lviv 🇺🇦, with table booking via WebApp and custom Django admin site (only Ukrainian)
• @inrium_bot — event management bot for a tabletop RPG community INRIUM in Ukraine 🇺🇦 (only Ukrainian)
• Discord events bot for INRIUM — publishes and processes game events
Server with bot & Channel where bot publish events and processes them, synced with Telegram bot
🎯 What I can help with:
• Telegram and Discord bots of any complexity (including WebApp)
• Backend APIs (FastAPI, Flask, Django) + third-party/API integrations
• Process automation and automation test coverage
• CI/CD pipelines and cloud infrastructure (AWS, GCP, Terraform), Linux, Docker
• Full-cycle delivery: Backend + Frontend + Deployment
🛠️ Tech stack:
Python, Django, FastAPI, Flask, telebot, aiogram, PostgreSQL, JavaScript, React, Docker, GCP, AWS, Terraform, SQLAlchemy, pytest

4454 USD INRIUM Bot (Telegram + Discord)
Bot Development
Bot for the INRIUM role-playing community with event processing and synchronization between Telegram and Discord
Here you can:
• Join an event in the Telegram channel or in the Discord thread
… • Add reminders to the calendar
As an INRI master, you can also:
• Create a set for role-playing, with all details considered
• Recruit participants, and only then add the date and time
• Manage your existing events
• Approve participants
• Remove and add players independently
Available event details:
• Date, time, event location
• Game type, setting, genre
• Cost (+donation)
• Character level
• Restrictions/warnings
• Additional tags
As an INRIUM admin, you can also:
• Enable and disable moderation
• Approve participant events (when moderation is enabled)
• Customize text for special events and Newbie events and links for donation events
• Ban and unban players
• Add tags for systems, genres, and warnings
In Discord (discord.com/invite/inrium), the bot publishes events with the option to join. All events are synchronized between the Telegram channel and the Discord thread.
The bot also automatically approves events of active players (a master has 3+ approved events with participants).
The bot is created on a volunteer basis, with further collaboration on a commercial basis, so the project price is calculated only based on the number of hours I spent on development.
Stack: Python, telebot, Django, PostgreSQL, GCP

2784 USD Telegram bot Secret Santa
Bot Development
A convenient bot for Secret Santa events, with over 30,000 active participants from around the world.
Here you can create an event, manage existing events, and anonymously message your Secret Santa.
• The bot will help you organize the event; you just need to share it in the chat with participants or individually with each one.
… • When all participants gather, you will close registration, and the bot will randomly shuffle people to determine who gives a gift to whom.
• Participants will be able to anonymously message their match to clarify the gift, address, etc.
The bot supports all types of messages and reactions, as well as two languages simultaneously.
With over 30k users and the limited Telegram interface, there have been fewer than 100 support requests in all 5 years of operation.
The project was created on my own initiative (for a friends' chat) and has always been free for users (with an option to donate), so the project's price is calculated only based on the number of hours I spent on development.
