Architect and optimize data storage solutions, including distributed databases (e.g., Citus, PostgreSQL, Snowflake) to meet high availability and scalability requirements. Collaborate with engineering teams to define architecture blueprints, reference implementations, and technical standards. Perform architecture reviews, provide hands-on technical guidance, and ensure adherence to best practices in code quality, testing, observability, and security. Evaluate new technologies, frameworks, and tools; recommend and drive technology adoption aligned with long-term architectural goals. Work closely with DevOps, SRE, and security teams to ensure efficient CI/CD, infrastructure automation, and secure system design. Provide architectural support for customer-facing issues, performance bottlenecks, and production incidents.
