What I'm looking for

I am looking for a challenging role in a dynamic environment that fosters innovation and collaboration, where I can leverage my skills to build efficient backend solutions and lead teams towards success.

I am a Senior Python Engineer with over 7 years of experience in designing and optimizing scalable backend systems, APIs, and databases. My expertise lies in Python, Django, FastAPI, Flask, PostgreSQL, and AWS, with a strong focus on performance optimization, scalability, and automation. I have a proven track record of leading teams and enhancing system efficiency for high-traffic applications that process over 50,000 daily transactions.

At BuuPass, I achieved a remarkable 10x performance improvement by optimizing SQL queries and implementing asynchronous processing. I also reduced third-party API failure rates by 30% through improved error handling and alerts. My role involved leading a team of developers to maintain and upgrade the Bus Management System, which processes over 10,000 daily ticket sales. I am passionate about building robust, efficient, and secure backend solutions that drive business success.
