What I'm looking for

I am looking for a role that fosters innovation, collaboration, and growth opportunities.

I am a Senior Backend Engineer with 9 years of experience in building scalable systems using Python, Django, and Node.js. My journey has been marked by designing and optimizing APIs that handle millions of monthly requests, significantly reducing database load through indexing and performance tuning. I thrive in collaborative environments, working closely with frontend developers, DevOps, and product teams to deliver reliable features and streamline deployments on AWS.

At Prosper, I led core backend engineering initiatives for the personal loans platform, architecting robust back-end services that directly contributed to $220M in additional annual revenue. I also developed automated ML-driven fund allocation systems, enhancing investment revenue by 30%. My commitment to quality is reflected in my ability to reduce opt-out complaint rates by 90% through effective integrations and automation, ensuring compliance and operational efficiency.

Throughout my career, I have consistently focused on maintainability and cross-functional collaboration. I have mentored junior engineers, led code reviews, and introduced best practices that improved team performance and code quality. I am passionate about leveraging technology to solve complex problems and drive business success.
