• Design and manage relational data models (e.g., PostgresSQL) and implement business logic for data-heavy applications.
• Work with Firestore or other NoSQL systems for audit trails and flexible data storage needs.
• Build and maintain Pub/Sub-based event-driven services to support scalable, decoupled microservice communication.
• Participate in the entire software development lifecycle, from requirements analysis and design to deployment and monitoring.
• Maintain and improve code quality through testing, documentation, and code reviews.
• Contribute to sprint planning, story grooming, and technical estimation.
• Collaborate with QA during manual and automated regression testing cycles.
• Support operational readiness through DevOps collaboration and CI/CD process ownership.

Project and Delivery Ownership

• Own complex epics and cross-cutting technical concerns (e.g., observability, audit logging, billing).
• Drive end-to-end delivery of high-impact features, ensuring scalability, security, and maintainability.
