Backend developer, mostly Python. I write Telegram bots, payment integrations and automation for web services, plus the backend bits that keep them running.
Most of my work is in private client repos. The public ones here are pieces cut out of real projects with the client-specific parts removed, so each repo is a single piece, not a whole product.
Open to freelance work. Telegram @krs_nik, email rampadian@gmail.com.
