Python
Advanced Python expertise: FastAPI, Flask, Django, banking SDKs, automation, reverse engineering with Frida, scraping, cryptography and MongoDB/Redis integration.
Python has been my primary language for over 12 years. I use it across projects ranging from banking SDKs with RSA/AES cryptography to full SaaS platforms with FastAPI, as well as reverse engineering tools and infrastructure automation.
