TranslateFlow — instant translation of input fields on any website
Web Programming
TranslateFlow — instant translation of input fields on any website
You write in any language — click "Translate Field" — and the text is already translated in real time.
This is a Chrome extension that works across the entire browser (on all websites without exception).
How it works:
…
You write in any input field (chat, form, comment, Telegram, Gmail, Notion, any website) in your native language.
You click the "Translate Field" button (or use the hotkeys Ctrl + Shift + 3).
In a second, the text in the field is already translated into the desired language (English, German, Polish — whichever you choose).
Automatic language detection + translation of selected text also with one click.
It shows the confidence level of the translation (for example, 85%) and a "Copy" button.
Main features:
Works in real time directly in input fields (no need to copy-paste into Google Translate).
Active on all Chrome websites (including chats, social networks, CRMs, banks, government websites, etc.).
Hotkeys: Ctrl+Shift+3 — translate field / selected text.
Elegant popup with message translation (as shown in the screenshot).
Settings: auto-detection, target language, disable/enable on specific websites.
For whom:
Freelancers and teams communicating with foreign clients.
Ukrainians working with English-speaking services.
Anyone tired of copying text back and forth.

FilmAdvisorBot
Python
FilmAdvisorBot is an intelligent Telegram bot designed to assist film photographers in accurately determining exposure using a smartphone as a digital light meter.
The bot transforms the smartphone into a precise lighting analysis tool. The user photographs the scene with their phone and sends the image to the bot. Using image analysis algorithms, the system determines the optimal exposure parameters — shutter speed, aperture, and exposure compensation — taking into account the specific camera, lens, and type of film the user has.
… Main functionality
Exposure analysis
Scene brightness assessment
Recommendations for shutter speed and aperture
Exposure compensation calculation
Consideration of ISO and film dynamic range
Adaptation to lens and camera characteristics
Film emulation
Grain simulation
Simulation of color profiles for different types of film
Contrast and tonal adjustments
Vignette addition
Result preview
Intelligent recommendations
Advice on film selection according to lighting conditions
Warnings about the risk of blur
Warnings about underexposure and overexposure
Recommendations for challenging shooting conditions
User profile system
Saving camera settings

Access Bot
Bot Development
Access Bot is a Telegram bot designed to automate the process of verifying users before granting access to closed channels related to cryptocurrency topics. The main functionality lies in verifying identity through a unique identifier (UID) and providing access only to those users who have confirmed their registration in the system.
The bot is built with principles of security, flexibility, and complete autonomy in mind. All actions are performed automatically—from UID verification to sending invitations to the channel.
… Functional capabilities:
User verification by UID from a local or remote database.
Automatic invitation of confirmed users to closed Telegram channels.
Administrator panel with full control over the bot:
editing texts of all messages;
viewing user activity statistics;
monitoring action logs.
Protection against unauthorized requests and double authorization.
Flexible notification system for administrators.
Technological foundation:
The bot is developed in Python using the Aiogram library for asynchronous interaction with the Telegram API. User data and verification results are stored in SQLite, ensuring speed and stability of operation.
Result:
Access Bot provides an efficient, secure, and fully automated process for controlling access to private crypto communities. The solution combines the stability of server logic with an intuitive interface and is suitable for any Telegram channels where user verification is required before joining.
