I build reliable scraping, data-extraction and API automation tools for websites and business workflows. My experience includes Python, C#/.NET, PostgreSQL, REST APIs, browser automation, structured data pipelines and production systems that collect and normalize marketplace data such as Bazoš listings. I can design a new collector or repair an existing one, add deduplication and validation, improve speed and resilience, connect downstream databases and services, and provide reproducible tests and operating documentation.
