System Administrator, Python, Go and PHP developer

I'm experienced PHP, Python and Go backend dev with good knowledge of Linux administration, multiprotocol VPN networks configuration and task automatization. I do a lot of automated scraping/extracting misc. content from many different sites (for me it's kind of like a puzzle that I really enjoy) and I do like to reverse-engineer things (android apps but not only) almost as much as reading RFCs (it's all there;). I work fast and I'm always open to negotiation
