158 USD Bot for tracking expenses and income
Bot Development
I created a Telegram bot for tracking expenses and income, specifically for a person who conducts financial literacy courses.
In this bot, it was possible to:
add savings banks to see where the money goes
… record income and expenses
make joint collections, for example for group goals or courses
set spending limits
Initially, integration with banking systems was planned to automatically pull in cash flow, but the client decided to leave the basic version without this.
The bot makes accounting simple and convenient, gives the owner a clear picture of finances, and allows for money control without complicated spreadsheets.

282 USD Telegram bot for room booking
Bot Development
IN THE PHOTO, THE BOT IS RUNNING UNDER A DIFFERENT TOKEN
I created a Telegram bot for room booking so that people can book a space as simply and effortlessly as possible.
The user enters the bot, selects the desired street, then the date and hours, makes the payment immediately - and the room is automatically reserved for them.
… No calls, no correspondence with the administrator, no confusion.
After payment, the booking is saved in the system, and another user cannot physically select the same time - even if they are also in Telegram. Everything updates in real time.
I also added an admin panel directly in this bot.
The administrator can see all bookings, occupied and free hours, manage rooms, locations, and payments - without third-party services and complicated admin panels.
Payment works automatically: after the payment, the system itself adds the booking, records it in the SQL database, and sends notifications to the admin and the client.
The entire bot is built to:
avoid double bookings
eliminate manual work
remove the human factor
In fact, this is a full-fledged booking system that operates 24/7 and takes a lot of routine processes off the business.

338 USD Telegram bot for a cafe
Bot Development
I developed a custom Telegram bot for a café that completely addresses menu management issues without complicated admin panels, third-party services, and technical knowledge.
The main idea of the project is to give the café owner full control over the menu directly in Telegram.
… Key features:
Admin panel directly in Telegram
The owner or administrator can manage the menu through the bot:
add new items
upload photos
set and change prices
edit descriptions
hide or delete products
manage delivery
No programming, no unnecessary connections, no external control panels.
Automatic menu updates
All changes:
are updated instantly
are displayed to customers without restarts
work 24/7 in real-time
Flexible integration options
The solution easily adapts to any business infrastructure:
Integration with the website - the bot automatically pulls the menu from the web resource
Through a separate admin bot - for convenient content management
Through an existing database or menu service - if you already have a menu in another system, the bot retrieves the data and keeps it up to date
The business does not adapt to the bot — the bot adapts to the business.
Result:
Complete autonomy for the owner
Minimum manual work
Quick information updates
Fewer errors
Scalable solution ready for network growth
Conclusion:
This bot is not just a menu.
It is an automation tool that simplifies operational processes and saves time and resources for the business.
In the photo, there is a piece from the bot itself, without a splash screen and the correct name.

226 USD Auto-publishing content in TG from open platforms + from closed ones
Bot DevelopmentI implemented an automatic content autoposting system in Telegram, which collects information from open sources as well as from private thematic chats, and publishes it to the required channel without manual human involvement.
The main task is to obtain relevant content and deliver it to the audience as quickly and reliably as possible.
Key features
… Autoposting from open sources
The system:
automatically retrieves information from open Telegram sources
operates in real-time
does not require manual copying or moderation

forwarding was restricted
content was available only to participants
I set up automatic message forwarding, which allowed:
to receive information without manual actions
to maintain the speed of publications
to ensure a stable flow of content
Processing and preparing content
Before publication, the system can:
clean messages from unnecessary elements
adapt the format for the channel
work with text, media, and links
