— Own the implementation of transactional features involving billing, payments, subscriptions, usage-based accounts, and revenue-related data.
— Design and evolve PostgreSQL schemas, data models, and queries while preserving data integrity, backward compatibility, and production stability.
— Analyze database performance and make informed decisions about data storage and access patterns, including when to use PostgreSQL, Redis, or ClickHouse.
— Build and maintain integrations with external platforms such as Stripe, HubSpot, and other business APIs.
— Develop administrative analytics and reporting capabilities that provide visibility into account activity, product usage, and revenue-related operations.
— Design reliable background processing and synchronization workflows with appropriate error handling, retry strategies, and observability.
— Contribute to architectural decisions and establish reusable patterns for transactional workflows, integrations, and admin functionality.
— Improve the maintainability and reliability of a large codebase through sound OOP principles, code reviews, testing, and refactoring.
— Collaborate with the team to evolve the platform’s data architecture and deliver scalable, reliable solutions as the product grows.
