What I'm looking for

I am looking for opportunities that foster innovation, collaboration, and growth in a dynamic tech environment.

I am a seasoned Software Engineer with a strong specialization in Golang, cloud technologies, and scalable backend systems. With a proven track record in developing high-performance solutions for large-scale platforms, particularly in the fintech and ride-hailing sectors, I thrive in multicultural environments and excel at implementing secure, compliant software systems. My experience includes developing high-sensitive services for a crypto exchange that handles over 2 million dollars worth of transactions daily.

Throughout my career, I have contributed to significant projects such as the development of a Block Reader service for blockchain transactions and a sophisticated OTP selection system that enhances user experience through various notification channels. My expertise extends to security and compliance, where I have spearheaded the development of high-concurrency authentication and authorization systems for Iran’s largest ride-hailing platform, managing over 50 million users and 50,000+ requests per second.

In addition to my technical skills, I have actively contributed to open-source projects, enhancing cloud-native messaging systems and developing secure OAuth 2.0 services. My journey has deepened my understanding of distributed systems and the challenges of achieving consensus in blockchain environments, making me well-equipped to tackle complex engineering challenges.
