Experience - Database Architect
  • Designed a hybrid OLTP/analytics architecture on AWS (Aurora PostgreSQL + Redshift) for a 24/7 ecommerce platform, improving p95 checkout query latency from 420ms to 180ms while supporting 35K peak TPS.
  • Led a migration from Oracle 12c to PostgreSQL 14 for 18TB across 120 schemas using AWS DMS and Flyway, cutting annual licensing costs by $1.1M and holding downtime to 22 minutes.
  • Implemented partitioning, indexing standards, and read-replica routing for a 9-node PostgreSQL cluster, reducing storage bloat by 38% and stabilizing nightly ETL runtimes under 2 hours.
  • Established data governance and reliability practices (logical replication, PITR backups, KMS encryption, and Datadog monitoring) achieving 99.95% database availability and passing two SOC 2 audits.

Interviewer
[question] Walk me through how you approach designing a database for a new service that expects rapid growth.
You
[answer] I start by clarifying access patterns and SLAs, then model the core entities and choose a primary store (usually PostgreSQL) with clear boundaries for OLTP vs analytics; from there I define keys, constraints, partitioning strategy, and a baseline index set, and I validate it with representative load tests before locking in replication, backup (PITR), and monitoring requirements.
Interviewer
[follow up] We have a slow query that spikes CPU during peak traffic; what is your troubleshooting sequence and what changes do you typically make first?
You
[answer] I capture the query and parameters, check pg_stat_statements for frequency and total time, review EXPLAIN (ANALYZE, BUFFERS) to see scan type and I/O, and then address the biggest lever first: missing/incorrect indexes, overly wide SELECTs, and stale stats or poor join order; if needed I add partial or composite indexes, adjust partition pruning, and confirm improvements with A/B load tests and SLO-based dashboards.

Why practice first?

Interviews are high-pressure

Even strong candidates underperform without reps. Practice reduces stress and sharpens delivery.

Rehearsal builds muscle memory

You get comfortable telling your story, quantifying impact, and handling curveball follow-ups.

Feedback accelerates improvement

Immediate, actionable notes help you close gaps before the real interview.
