Message

At Danesh Gostar Sina, I design and maintain production automation systems that interact with Instagram’s private APIs, focusing on request reliability and session management.

I built a custom HTTP client with TLS fingerprinting to mimic official mobile app behavior, reducing blocked and failed production requests. I also developed reusable controller layers for API calls, response parsing, error classification, and traffic monitoring.

As a freelancer, I architected a Django REST backend for OTP-based phone authentication and user management, including configurable phone-number and IP blocking after failed login attempts.

I also developed a FastAPI backend following Clean Architecture principles, with JWT authentication and protected endpoints. Earlier, as a Software Tester Intern at Nadin Soft, I increased Cypress test coverage by 25% and documented defects in Jira.
