What I'm looking for

I am looking for a role that challenges me technically and allows for mentorship opportunities while fostering a collaborative and innovative work environment.

As a Staff Software Engineer with over a decade of experience, I have a proven track record of designing and implementing scalable systems that drive efficiency and enhance user experiences. At Seamless.AI, I led the development of a tenant-isolated data ingestion system, integrating millions of records daily while ensuring high availability and security. My work in architecting microservices in Go significantly reduced latency and improved data query performance, showcasing my ability to leverage modern technologies for impactful results.

Previously, as a Senior Software Engineer at Amazon, I designed a recommendation engine that processed millions of user interactions in real-time, contributing to a 60% increase in transaction completion rates. My collaborative approach with cross-functional teams has allowed me to streamline processes and enhance system performance, ensuring compliance with security standards while delivering responsive user interfaces. I am passionate about mentoring junior developers and fostering a culture of continuous improvement and innovation.
