What I'm looking for

I'm seeking long-term remote opportunities in product-driven startups that value innovation and collaboration.

I'm a Senior Backend Engineer with over 9 years of experience in building scalable backend systems using Python. My journey has taken me through various roles where I've honed my skills in cloud infrastructure and observability. At PayPal/Venmo, I led the migration of Python applications from version 3.5 to 3.9 and successfully rolled out AWS EKS, significantly improving system reliability and performance.

Throughout my career, I've focused on designing and implementing high-performance microservices and serverless architectures. My experience includes developing ETL pipelines for Hadoop clusters and integrating AWS services to enhance data processing workflows. I thrive in product-driven startups and am passionate about creating clean architecture and efficient systems.
