What I'm looking for

I seek senior engineering roles building scalable backend and data platforms, collaborating cross-functionally, driving migrations, and delivering measurable user impact.

I am a results-driven senior backend engineer with over nine years of experience designing, developing, and deploying scalable, reliable backend systems for large-scale data platforms. I have led cross-functional projects at Google and SAP Ariba, owning designs, migrations, and new service implementations that improved performance and user satisfaction.

Notable achievements include reducing privacy review approval time from over five days to under one day, migrating 100% of traffic to new services with zero user impact, and contributing to a company-wide database migration from Oracle to HANA while receiving the SAP Catalyst Award. I focus on pragmatic architecture, measurable outcomes, and close collaboration with stakeholders to deliver high-impact solutions.
