https :// github . com / OlegChausov / FAST _ scriber
Fast Scriber Fast Scriber is an offline audio transcription tool
focused on predictable user experience, clean architecture, and
minimal JavaScript usage. It supports playback, editing, and
downloading of transcript segments without page reloads. Designed
for journalists, editors, bloggers, writers, and anyone else who needs
reliable transcription. All data is stored locally on your device. Fully
offline. Free use is encouraged. Contributions and improvements are
welcome.
Features
· Transcription of audio/video using one of six available models
(Faster Whisper)
· Asynchronous processing and streaming file uploads
· Segment playback directly within the interface
· In-browser transcript editing without page reloads
· Automatic cleanup of inactive files after 30 days
· Download transcripts in .txt and .docx formats
· Fully offline mode — no cloud dependency
Technology Stack
Component Purpose

FastAPI Backend: routing, API, file handling
Faster Whisper
(OpenAI) Transcription: fast and accurate models (note: last
three models are hardware-intensive)
FFmpeg Audio/video processing: track extraction
SQLite Storage: metadata, trash bin, segments
JavaScript
(minimal) UX: playback and editing without page reloads
AsyncIO Asynchronous request and background task
handling
Uvicorn ASGI server: application launch and stream
management
Architectural Highlights
· Streaming and in-memory processing for enhanced security
and performance
· Self-cleaning trash bin — removes old files without user
intervention
· Explicit routing and controlled flows — no hidden logic, just
predictability
· Modular structure — easy to extend and maintain
· Background processing — upload files and continue working
without waiting

https://github.com/OlegChausov/rembase
Application for managing orders and clients. Designed for small
service centers, repair shops, auto service stations, and home or
field-based technicians. This is a web application intended for use
within a local network. Compatible with Windows, macOS, and Linux.
All data is stored locally to prevent leakage and ensure full control.
Tech stack & architecture:
· Backend: Python with Django framework
· Frontend: Django Template Language, JavaScript, Bootstrap,
Select2, jQuery

· Database: SQLite3 — supports ACID transactions for data
reliability. Stored as a single file, managed via Django ORM,
and kept locally.
Key features:
· Order management: Track order statuses, calculate payment
amounts, and assign completion times
· Client database: Clients can be created dynamically during
order entry; full history of related orders is preserved
· Work records: Includes predefined job types and detailed
records of completed work
· Company profile: Editable section for company details
· Staff management: Assign staff to orders, onboard or dismiss
employees, and maintain history of their work
· Document printing: Generate printable intake and delivery
forms for orders

https://github.com/OlegChausov/Text_Clarifier
Text_Clarifier is an application for reviewing, editing, and evaluating
texts submitted by authors, journalists, and others.
User Features
· User registration, profile editing, and soft deletion
· Login/logout without page reload (HTMX)
· Secure cookie-based session using JWT tokens
· Soft deletion of accounts (ON DELETE SET NULL)
Data Management
· Uploading text content
· Editing texts with appropriate permissions
· Deleting texts with appropriate permissions
· Field-level editing for reviewers/editors based on role
permissions
Admin Panel
· Assigning and changing user roles
· Managing role-based permissions (default setup includes 3
roles with 3–12 permissions each)
Stack and Technologies
· Core framework: FastAPI
· Fully asynchronous backend
· Minimal JavaScript (via unpkg CDN)

· Current database: SQLite (for demo and educational purposes;
started with PostgreSQL and plan to migrate back)
· ORM: SQLAlchemy
· Migrations: Alembic
· Templating: Jinja2
Architecture
· Relational tables: users, texts, roles, permissions,
role_permissions (in Django, this would be auto-generated)
· Permissions stored in the permissions table; new permissions
added as records — no migrations required
· Templates extend each other for layout reuse
· Routers support both GET and POST methods
· Passwords hashed using Passlib
· JWT tokens used for cookie-based authentication

https://github.com/OlegChausov/EventPulse
EventPulse is an application to tracking the appearing events:
concerts in Vilnius and Warshaw and movies in Minsk
Instead of constantly checking websites, users can leave a query for
a future movie or concert. When such an event is found, the app will:
· Display it in the event list
· Send an email notification with a link to buy tickets
· Users can add or remove queries and events, manage them
(stop searching, continue searching, etc.).
Authentication
· Registration and login with password (secure, password hashes
only, not stored in plain text)
· Login via Google account (OAuth0)
· Supports Russian and English languages
Tech Stack
· Python + FastAPI (asynchronous backend)
· BeautifulSoup (web scraping/parsing)

· PostgreSQL (database, can be replaced with another DB)
· HTMX JS (dynamic pages)
· OAuth0 (social login, configurable)
· SMTP Yandex (email notifications, configurable)
· Materialize CSS (UI/UX — clean and stylish design)
Features
· Middleware with JWT tokens for session management
· Private, public, and semipublic routes
· Autorenewal of expiring sessions on user activity
· Language detection from browser if not explicitly chosen
· Passwords stored only as secure hashes
· Fully asynchronous — scraping does not block the app
· Configurable matching level between queries and events
· Safe password hashing and storage
