Database Transaction Not Rolled Back on Error
When an operation fails partway through, previous changes aren't rolled back. Database is left in inconsistent state with partial changes. For example: charge credit card but fail to record order = customer charged but no order created.
Transaction management exists but doesn't properly rollback on all error types.
Error Messages You Might See
Partial data persisted after error
Inconsistent database state after failed operation
Transaction didn't rollback on exception
Common Causes
- Exception thrown but not marked for rollback (@Transactional with wrong rollbackFor)
- Catching exception and suppressing it, transaction commits anyway
- Method not annotated with @Transactional, each query auto-commits
- Nested transaction not properly configured
- try-catch without re-throwing prevents rollback
How to Fix It
Use @Transactional(rollbackFor = Exception.class) on method. Don't catch exceptions you can't handle. If catching, log and re-throw. Use @Transactional at service layer. Test transactions by forcing failure mid-operation. Verify nothing persisted on failure. Check transaction logs to confirm rollbacks.

15+ years shipping production infrastructure for startups. Former CTO at qed.builders (acquired by The Sandbox).
Cursor ambassador and agentic tooling builder.
I've scaled systems, automated deployments, and built observability tools for AI coding workflows. I specialize in taking vibe-coded apps from broken prototype to production-ready: fixing Supabase auth/RLS, Stripe integrations, deployment pipelines, and cleaning up AI-generated spaghetti.
I build tools in this space (agentprobe, claudebin, micode) and understand both sides: how AI generates code and why it breaks.

I'm a full-stack developer focused on building practical and scalable web applications. My main experience is with **React, TypeScript, and modern frontend architectures**, where I prioritize clean code, component reusability, and maintainable project structures.
I have strong experience working with **dynamic forms, state management (Redux / React Hook Form), and complex data-driven interfaces**. I enjoy solving real-world problems by turning ideas into reliable software that companies can actually use in their daily operations.
Beyond coding, I care about **software quality and architecture**, following best practices for componentization, code organization, and performance optimization.
I'm also comfortable working across the stack when needed, integrating APIs, handling business logic, and helping transform prototypes into production-ready systems.
My goal is always to deliver solutions that are **simple, efficient, and genuinely useful for the people using them.**

Get HelpFrequently Asked Questions
How to ensure rollback on all errors?
@Transactional(rollbackFor = Exception.class). By default only rollbacks on unchecked exceptions. Checked exceptions don't trigger rollback unless specified.
Should exceptions be caught in transactional method?
No. Let them propagate so Spring framework can rollback. If must catch, re-throw after logging.
How to test transactions?
Insert data, force error mid-operation, verify nothing persisted. Check database: SELECT COUNT(*) should not increase.
