About

I specialize in billing and revenue operations within SaaS environments, with a focus on making complex systems and workflows actually work in practice. My role has evolved from support into owning billing systems, contract workflows, and cross-functional initiatives across Monetization Engineering, Legal, Sales (GTM), and Support teams. I work closely with engineering on pricing and billing logic, ensuring contracts, provisioning, and invoicing behave correctly end-to-end. Some of the areas I focus on: - Billing systems and contract-to-cash workflows - Monetization logic, pricing, and provisioning accuracy - Cross-functional process improvements across GTM, Legal, and Engineering - Identifying and resolving system-level issues that impact revenue I’m particularly interested in roles where I can continue to bridge the gap between systems, operations, and real-world customer impact - especially in fast-scaling SaaS environments.
