Optimize Database Storage for Web Access

I need our database layer re-designed so that records load faster and more reliably through the web application. The focus is squarely on improving data accessibility: queries must return results quickly, and common user actions should no longer be blocked by heavy reads or locking issues. Work begins with an audit of the current schema, index usage, and query patterns. From there, produce an optimized structure, add or adjust indexing, and recommend any caching or sharding techniques that match the projected growth of our data set. Wherever possible, keep the solution portable across standard relational engines (PostgreSQL or MySQL are most relevant right now) and cloud hosting environments. Acceptance criteria • Revised schema and index scripts in executable SQL. • A concise architecture diagram outlining data flow from storage to the web front-end, noting any caching tiers or read replicas you introduce. • Migration plan with rollback steps and performance benchmarks that demonstrate measurable gains in response time. Please weave any required tools—such as pgAdmin, MySQL Workbench, Redis, or AWS RDS—naturally into your proposal if they figure into the solution. Clear, well-commented deliverables and brief supporting documentation will let my in-house team deploy the improvements with confidence.
