I’m a backend and automation developer with 3-4 years of hands-on commercial experience building and operating REST APIs, web and mobile backends, Telegram systems, parsers, browser automation, and AI-powered workflows. I’m comfortable owning the full delivery lifecycle—from architecture and implementation to containerization, deployment, optimization, troubleshooting, and support.

I’ve developed, deployed, and maintained 86 Telegram bots with a combined user base of approximately 600,000 users. I also automated content publishing and distribution across 200+ Telegram channels, while supporting backend applications with user bases of approximately 5,000–50,000 users per application—sometimes running up to 8 services in memory-constrained environments around 4 GB of RAM.

On the engineering side, I design modular FastAPI applications (routers, schemas, services, repositories, integrations, tasks, and database layers) and build REST APIs for websites, iOS/Android applications, internal tools, and Telegram-based products. I work with SQLAlchemy, Pydantic, MySQL, ClickHouse, Redis, and SQLite, and I integrate Celery and RabbitMQ for queues, retries, and controlled workload processing.

I also build automation and AI workflows end to end: ZennoPoster/Selenium/BeautifulSoup-based parsers and browser automation, Telegram Bot API integrations, and local AI generation via bot-based pipelines (and experimentation) that produced thousands of images. I’ve operated production services on self-managed infrastructure without a dedicated DevOps team using Docker, process management, logging, recovery, and resource optimization, and I prefer remote, contract/full-time, async, written-first collaboration with clear requirements and weekly milestones.
