backend-performance

Reduce API latency in NestJS or Fastify by auditing async I/O operations, optimizing connection pooling, and improving payload serialization. The post-implementation review workflow targets these areas specifically to increase throughput and improve overall service reliability.

Auditing PostgreSQL query performance in a Node 20+ application involves reviewing connection pooling configurations and query execution plans within a PostgreSQL-first stack. The audit workflow provides deterministic guidance to fix slow queries and instrument observability gaps across your TypeScript codebase.

Backend performance tuning works with Express and a PostgreSQL-first stack by applying a structured audit to code authored with Node 20+. It evaluates caching strategies, connection pooling, and observability to produce actionable improvements for reducing latency and increasing throughput.

Run a backend performance audit on your TypeScript service during post-implementation reviews when latency, throughput, or observability gaps become apparent. It enforces a deterministic workflow to guide fixes and instrumentation across Node.js backends using PostgreSQL.

Node.js backends experience throughput drops under heavy load due to unoptimized connection pooling, inefficient async I/O handling, or missing caching layers. A structured performance audit identifies these specific bottlenecks and provides an instrumentation plan to improve reliability.
