Python Backend
FastAPI, Django/DRF, REST API
/ PYTHON BACKEND DEVELOPER
FastAPI, Django, PostgreSQL, Redis and Celery. I work with external services, background jobs and existing codebases, including failure scenarios.
/ ABOUT
I'm a Python backend developer based in Stavropol. I build server logic, integrate external services, and work with databases and background jobs. I aim to leave understandable, testable code.
I keep building my own projects and I'm open to remote opportunities. My case studies cover both implementation and constraints.

FastAPI, Django/DRF, REST API
Webhooks, APIs, queues
PostgreSQL, SQLAlchemy, Redis
Celery, Telegram, background jobs
/ PROJECTS
Four projects that show how I work: the problem, implementation, engineering decisions and limitations.
TATTOTOYOU
Handles Telegram enquiries, answers common questions and hands difficult cases to the artist.
Webhooks, deduplication, background jobs, Inbox/Outbox and knowledge-base retrieval.
Retail Procurement API
Product catalog, shopping basket, order placement and supplier price-list imports.
Django/DRF, order transactions, PostgreSQL and Celery background jobs.
Code Review Bot
Reviews changed Python lines and posts structured feedback to GitHub Pull Requests.
Signed webhook verification, diff parsing, background jobs and Ruff fallback.
CUDY Home Gateway
Monitors OpenWrt health, records incidents and sends notifications.
Health checks, incident history, restricted actions and guarded update rollback.
/ MORE FROM GITHUB
Complementing the main cases: long-running jobs and a complete small web application.
Upscale Service
Accepts an image, processes it with EDSR and returns a result using the background task identifier.
Flask API, expiring Redis data, Celery worker and an end-to-end processing test.
Limitations: Upload size limits, retries and failure recovery need further work.
UserManager
A small web app with user listing, searching, editing and a REST API.
Flask CRUD, SQLite, JavaScript UI, server-side validation, Docker and pytest.
Limitations: Test coverage and recent CI results were not rerun as part of this review.
/ GAME / HTML5
Buy cars, repair them, make sales and grow your own workshop.
Dedicated browser build in preparation
/ INSIDE THE CASE STUDIES
Three specific topics from real projects. Each link opens an existing case study, not an invented article.
