62% faster app overall
8s → 0.8s report load time
Placeholder case study — replace with a real engagement before launch.
The problem
A SaaS product was growing nicely, but its database was struggling. Dashboards took up to 8 seconds to load, some reports timed out entirely, and the team feared a costly full rewrite. Customers were starting to notice the lag.
The approach
Rather than rebuild, we fixed the root causes:
- Profiled the slowest queries with execution-plan analysis.
- Added and reshaped indexes to match real access patterns.
- Refactored a handful of N+1 and full-table-scan queries.
- Introduced Redis caching for hot, read-heavy endpoints.
- Right-sized the AWS RDS instance and tuned its configuration.
The stack
PostgreSQL on AWS RDS, with Redis for caching.
The result
Heavy reports dropped from 8 seconds to around 0.8 seconds, and the application felt about 62% faster overall — all without a rewrite. The team avoided a major re-platforming project and got their roadmap back.
