Product & Platform Architecture Revenue Recognition & Accounting Automation Subscription Billing & Consumption Revenue Performance, Scalability & Observability Collaboration & Leadership

As one of the early engineers and now a Principal Software Engineer in the Zuora Revenue (RevPro) team, I have played a pivotal role in building, scaling, and modernizing the world’s leading Revenue Recognition and Automation platform — empowering enterprises to comply with ASC 606 / IFRS 15 while supporting complex subscription and consumption-based billing models.

• Led the re-architecture of RevPro from a PL/SQL-centric monolith to a cloud-native, microservices-based platform using Java, Spring Boot, and Temporal.io.
• Designed the Revenue Event Framework (REF) and Workflow Orchestration Layer, enabling distributed, fault-tolerant, and auditable processing of revenue events.
• Implemented multi-tenant SaaS architecture with strong data isolation, shared infrastructure, and dynamic configuration management.
• Engineered core integration pipelines for seamless synchronization between Zuora Billing, CPQ systems, and external ERPs.
• Built the Revenue Recognition Engine automating key processes under ASC 606 / IFRS 15 — including performance obligation identification, SSP (Standalone Selling Price) allocation, variable consideration, and contract modification handling.
• Developed configurable rules-based frameworks for event-driven recognition, revenue allocation, and schedule generation aligned with customer billing and delivery milestones.
• Designed audit-compliant reconciliation workflows linking billing transactions, contract lines, and journal entries with complete traceability.
• Implemented real-time recalculation logic for dynamic revenue contracts impacted by amendments, renewals, or usage events.
• Partnered with billing product teams to design bi-directional integration between Zuora Billing and Zuora Revenue, ensuring synchronization of subscriptions, amendments, renewals, and cancellations.
• Built the Usage & Consumption Revenue Module, supporting:
  High-volume metered usage ingestion and aggregation pipelines.
  Tiered, overage, and pay-as-you-go pricing models.
  Automated usage-based accrual and deferral logic integrated into the recognition engine.
• Enabled hybrid monetization models combining recurring, one-time, and consumption-based revenue streams.
• Delivered a 3x improvement in batch and workflow throughput by implementing shared JDBC connection pooling, Redis caching, and MongoDB for high-performance data processing.
• Deployed Temporal.io to coordinate asynchronous workflows such as event ingestion, allocation, and posting — ensuring transaction-level reliability and traceability.
• Integrated Prometheus and Grafana dashboards for system health, revenue batch metrics, and exception analytics, improving operational visibility and reducing support overhead.
• Partnered closely with Product Management, Finance SMEs, and Architecture Council to translate complex accounting policies into scalable, configurable product logic.
• Provided technical leadership and mentorship to engineers across microservice development, database optimization, and workflow orchestration.
• Drove engineering best practices including domain-driven design, observability-first development, and continuous integration/deployment.

• Led Oracle E-Business Suite (R12, 11i) implementations for enterprise healthcare and government clients.
• Developed and customized PL/SQL interfaces, XML Gateway maps, and BI Publisher reports.
• Designed and executed data migration routines, workflow extensions, and financial process automation.
• Mentored offshore teams and ensured delivery of key financial integrations under tight timelines.
