[Offer] Web Scraping | Backend Developer | Automation Engineer
I build scalable scraping systems, automation pipelines, and backend architectures designed to extract, process, and organize large volumes of data efficiently.
My main focus is web scraping and intelligent automation, developing systems capable of interacting with complex platforms, bypassing limitations, processing structured data, and integrating workflows across multiple services.
Beyond extraction itself, I create complete backend ecosystems around the data — APIs, dashboards, filtering systems, scoring engines, automation flows, and integrations designed for real production environments.
I focus on performance, maintainability, modular architecture, and long-term scalability.
