Project details
You will get expert PostgreSQL performance optimization and clean, reliable database migrations tailored to your environment. I specialize in reducing query latency, fixing bloat and autovacuum issues, stabilizing CPU/IO, and delivering measurable improvements backed by clear before/after metrics. I also handle end‑to‑end migrations from MySQL, SQL Server, or on‑prem PostgreSQL to AWS Aurora PostgreSQL with zero‑data‑loss workflows, schema conversion, and validation. With 8+ years of hands‑on experience in high‑load systems, I deliver solutions that are fast, safe, and production‑ready.
