• Design relational schemas, write optimized SQL queries, and work with PostgreSQL performance tuning (indexes, partitions, query planning).
• Implement caching strategies, rate limiting, distributed locks, and session storage using Redis.
• Build data validation pipelines and compliance-driven data flows ensuring data correctness and auditability.

5. Security, Reliability & Observability

• Implement authentication, authorization, encryption, and secure API practices.
• Build monitoring, alerting, metrics, and tracing systems using modern observability tools.
• Diagnose production issues, identify bottlenecks, and drive long-term fixes and improvements.

6. Code Quality & Technical Leadership

• Conduct detailed code reviews and ensure engineering best practices across the team.
• Participate in technical roadmap planning, architectural discussions, and system design decisions.
• Mentor junior and mid-level engineers; drive a culture of technical excellence and ownership.
