What I'm looking for

I seek roles building scalable backend and fintech platforms, with focus on system design, automation, cross-functional leadership, and measurable business impact.

I am a Staff Software Engineer with deep experience building scalable backend systems, microservices, and fintech platforms for global customers. I have led end-to-end projects including Debt-as-a-Service and a DeFi lending platform, integrating APIs and automation to accelerate client onboarding.

At Sivo I drove platform architecture, built dashboards and workflow automations, and helped onboard 100+ fintech clients across North America, Europe, Asia, and Latin America. Previously at Amazon and Airbnb I migrated monoliths to microservices, improved reliability and performance, and delivered secure, compliant telehealth and property-management solutions.

I prioritize pragmatic engineering, operational efficiency, and mentoring teams to adopt best practices; I enjoy solving complex distributed-systems problems and delivering measurable business impact.
