I will optimize your mongodb, postgresql, redis, and backend API performance

Slow APIs costing you users? I investigate and improve backend performance across MongoDB, PostgreSQL, Redis, and your API layer.

What I do: Profile slow endpoints and query plans Add missing indexes and fix inefficient queries Remove repeated DB calls and N+1 patterns Introduce Redis caching where it helps Share before-and-after latency findings from the work

Every package includes source code and clear notes on what changed.

What to send: the slow endpoint(s), sample payloads, DB schema or access, and current latency observations.

Past experience (not a guarantee): reduced average API latency from roughly 500 ms to 50 ms on a production system; built cache-first session reads with MongoDB and Redis.
