• Model data in PostgreSQL; design relational schemas, write optimized queries, and review migrations.
• Raise the bar on engineering quality: code reviews, testing strategy (unit/integration), CI/CD hygiene.
• Instrument & operate: add observability, track performance, debug production issues, and drive SLO-oriented reliability.
• Collaborate with design and product to shape roadmaps and sequence milestones.
