What I'm looking for

I seek a role building scalable, cloud-native backend and data systems where I can lead technical design, improve data quality, and mentor engineers in a collaborative, product-focused team.

I am a Senior Software Engineer with nine years designing and scaling eCommerce, data-driven, and cloud-based platforms. I focus on building maintainable, high-performance systems using Python, JavaScript, and AWS technologies.

At Square I designed microservices-based APIs and ETL pipelines for multi-channel product and order synchronization, implemented data quality rules, and integrated AI automation to reduce manual reconciliation.

Previously at Block and Yelp I built RESTful APIs, containerized microservices, and data normalization pipelines, improving throughput, search relevance, and moderation efficiency while collaborating closely with product and data science teams.

I bring hands-on experience with AWS, Docker, Kubernetes, Terraform, PostgreSQL, MongoDB, and CI/CD tooling, and I mentor engineers to raise code quality and operational transparency across platforms.
