Where Bottlenecks Impact Your Customers & Revenue

Real-world friction, checkout hesitation, and performance barriers that directly reduce conversions and customer retention.

01

Checkout & Application Freezes During Traffic Surges

Unindexed queries scanning millions of rows, pegging database CPU at 100% and causing application-wide timeouts.

02

Deadlocks & Transaction Failures Costing Sales

Poorly isolated concurrent write operations locking database tables, causing customer orders or updates to fail.

03

Overpaying for Massive Database Instances

Throwing expensive hardware at slow queries instead of fixing underlying database indexes and connection pooling.

04

Slow Internal Reporting Hurting Business Decision-Making

Heavy analytical queries locking transactional tables, preventing customer-facing operations from completing on time.

How We Fix It: The 14-Day Performance Sprint

A structured, milestone-driven engineering roadmap delivered directly into your staging repository with zero downtime.

PHASE 01 // DAYS 1–3

Slow Query Profiling

Enabling pg_stat_statements / slow query log to identify queries consuming 80% of execution time.

PHASE 02 // DAYS 4–7

EXPLAIN Execution Plan Review

Deep EXPLAIN (ANALYZE, BUFFERS) inspection; designing targeted composite and covering indexes.

PHASE 03 // DAYS 8–10

Non-Blocking Index Migration

Creating indexes concurrently (CREATE INDEX CONCURRENTLY) with zero table locking or downtime.

PHASE 04 // DAYS 11–12

Memory Buffer Optimization

Memory buffer configuration tuning (shared_buffers, work_mem) based on server hardware specs.

PHASE 05 // DAYS 13–14

Stress Testing & Alerting

Load testing under peak transaction volume and delivering automated slow-query regression alerts.
