Building a internal tool with SQL? Let us review it.
Expert code review for internal tools built with SQL. We fix SQL-specific security gaps, optimize performance, and handle deployment. From $19.
Common SQL issues we find
Real problems from SQL codebases we've reviewed.
SQL injection from string concatenation
Building queries by concatenating user input directly into SQL strings instead of using parameterized queries, enabling full database compromise.
Missing indexes on queried columns
Queries filter and join on columns without indexes, causing full table scans that slow exponentially as data grows.
SELECT * in production queries
Fetching all columns when only a few are needed, wasting bandwidth, memory, and preventing covering index optimizations.
N+1 query patterns
Executing one query per row in a loop instead of a single JOIN or batch query, multiplying database round trips by the number of records.
Internal Tool challenges to solve
Key internal tool concerns that AI-generated code often misses.
Access control
Who can see what? Internal tools need role-based access — finance sees revenue data, support sees customer data, engineering sees system metrics. AI tools build the dashboard but rarely implement granular permissions.
Data sensitivity
Internal tools often connect directly to production databases. A bug that deletes records or a missing auth check that exposes customer PII can have serious legal and business consequences.
Network security
Internal tools should be behind a VPN or protected network, not on the public internet. AI tools deploy to public URLs by default. Proper network configuration prevents external access.
Audit logging
When someone modifies data through an internal tool, you need to know who did what and when. This is essential for debugging, compliance, and accountability.
What we check
Key areas we review for SQL internal tool projects.
Access control — role-based permissions enforced server-side
Database security — read-only where possible, protected write operations
Network configuration — not publicly accessible, VPN or auth gateway
Audit logging — who did what, when

Frequently asked questions
Can you review a internal tool built with SQL?
Yes. We regularly audit SQL internal tool projects and understand the specific patterns and pitfalls of this combination. Our review covers security, performance, and deployment readiness.
What issues do you find in SQL internal tools?
Common issues include sql injection from string concatenation and missing indexes on queried columns on the SQL side, combined with internal tool-specific concerns like access control and data sensitivity. We check for all of these and more.
How do I make my SQL internal tool production-ready?
Start with our code audit ($19) to get a prioritized list of issues. For SQL internal tool projects, the typical path is: fix security gaps, address internal tool-specific requirements, optimize SQL performance, then configure deployment. We provide a fixed quote after the audit.
How long does it take to audit a SQL internal tool?
Our code audit delivers a full report within 24 hours. For SQL internal tool projects, we check security, architecture, performance, and deployment readiness across all SQL-specific patterns. Fixes are scoped separately with a fixed quote.
