I build and maintain backend automation systems — Python scripts, data pipelines, and Linux server infrastructure — for teams that need reliable, hands-off operations. What I handle: - Python Automation: Scripts for scraping, scheduling, data processing, and third-party API integrations (REST/Websocket) - Linux & Server Administration: Setup, configuration, and troubleshooting of Ubuntu/Debian servers, Nginx/Apache, and Docker-based deployments on AWS EC2 - Data Pipelines: ETL scripts that clean and transform CSV/JSON/XML data into structured formats, with logging and error handling built in - Database Work: PostgreSQL, MongoDB, and SQLite — schema design, deduplication, and automated data loading - API Integration & Event-Driven Orchestration: Building headless REST APIs (Django REST Framework) and securing them with Token Authentication. Designing real-time, event-driven webhooks and asynchronous business logic pipelines using orchestration engines like n8n. I'm a clear communicator, respond fast, and I test everything before I call it done. If you need something built and then actually maintained — not just handed off broken — let's talk.

I am Thailand based software engineer from Russia. I have 10 years of experience in commercial programming, but have been into CS since I remember myself. My main language is PHP, which I am expert in. JS is my second language, but I can use several others to build specific microservices or scripts if it is more efficient. I’m a fast learner and do really love problem solving because I'm good in it and really into joy of it as well. I’ve worked in many different niches, my current one is affiliate marketing, which I am currently an expert in. Also an expert in Facebook API, different CPA Trackers, such as Voluum, RedTrack and Keitaro and other media buying tools. My latest job was building a CPA Tracker in the role of CTO, with a team of 10 people for 3+ years. I’m able to build and manage teams from scratch but I still will work in them as a developer, as this is my passion. I build great designs for both small and huge projects, as small projects sometimes grow big, and I consider further scaling in the design. I’ll be best in building something that nobody has ever done and has any idea how. Or something like an admin panel connected to a resource with huge traffic with several microservices, tied with lots of 3d party APIs. I’m also good at building chat bots, trade bots, crypto currencies stuff like exchanges or payment gates, automations for different processes. I’m a mediocre frontend developer, but can build fast frontend MVPs using jQuery though I’m familiar with modern frontend frameworks. Anyway, I actually can do anything. All my code is covered with tests and well documented (OpenAPI Swagger). I like to use the latest versions of software. My main stack: PHP, Laravel, JavaScript, JQuery Postgres, MySQL, ClickHouse Redis, RabbitMQ, Memcached Linux Jira, Confluence, ClickUp, Slack, Loop Of course I know GIT There are a great list of other technologies and languages I use from time to time, but I can’t say I’m an expert in them. Regarding AI, it’s a very helpful tool in experienced hands, which I use quite a lot, but sometimes it’s faster for me to write the code than the prompt, which should always be carefully checked and tested. No vibecoding, it produces a bad codebase which no one truly understands. I'm opened to interesting complex projects in all areas.
