I am a backend-focused software engineer with deep expertise in Python-based systems, specializing in large-scale data collection, automation, and high-reliability backend services.

My work revolves around building systems that operate in real-world constraints:
anti-bot protections, unstable networks, large data volumes, long-running jobs, and production environments where failure is not an option.

I care deeply about clean architecture, maintainability, and performance under pressure.
