SaaS Code Audit & Production Rescue

When an audit is the right next step

Your demo works, but you cannot explain who can access each customer’s data, whether billing survives retries, or how to recover a failed deployment. You may have paying users, a stalled handover or an AI-generated MVP that has become difficult to change. Start with an evidence-based production readiness audit before committing to a rewrite.

1. Audit: understand the product and prove the risks

We agree the critical journeys and review boundaries first. I inspect architecture, dependencies, authentication, authorization, data access, payment processing and deployment configuration. Findings include reproduction steps, affected code, business impact and a prioritized remediation plan. The handover distinguishes verified defects, design trade-offs and areas that could not be tested.

What the review covers

For a Next.js code audit: server/client boundaries, route protection, input validation, caching of user-specific data, error handling and deployment behavior. For a Supabase security audit: tenant boundaries, row-level security, privileged server access and storage policies. Payment review covers duplicate and out-of-order events, reconciliation, refunds and entitlement changes. AI app code audits also examine tool permissions, untrusted inputs, evaluation coverage and human escalation.

2. Remediation: fix the highest-impact problems

After the review, we agree a separate implementation scope. I follow the existing architecture, address root causes, add regression checks for the affected behavior and prepare a staged release with rollback steps. You receive reviewable changes and evidence of what passed. A working foundation is retained wherever possible; a rewrite needs a specific technical reason.

3. Ongoing engineering: keep production maintainable

After release, ongoing work can cover monitoring, incident follow-up, dependency maintenance and the next product milestones. We agree ownership, availability and priorities explicitly. This is a continuation option, not a requirement to receive your audit findings or code.

Lovable, Cursor and Replit app rescue

The tool that generated the code is context, not a diagnosis. I inspect the actual repository and connected services. Rescue may mean tightening authorization, replacing a fragile integration or making deployment reproducible. Moving off a builder and changing the application architecture are separate decisions; see when to move off Lovable.

Production experience behind the review

My existing work includes VenueX AI as Lead Engineer, Database Vault as founder and full-stack engineer, and Dryva for booking, tracking and payments. These case studies demonstrate implementation experience; they are not claims that those clients commissioned this audit service.

Scope, access and deliverables

Send the stack, repository size, stage of the product, launch deadline and the journeys you are most worried about. Share architecture notes or a sanitized example initially; do not send passwords or production customer data in an inquiry. Review access and a safe test environment are agreed after scoping. The proposal identifies the systems included, exclusions, deliverables, schedule and fee before work starts.

Start with the uncertainty you need resolved

Request an audit and describe what would prevent you from launching confidently. Need a new product instead? See Next.js SaaS development. Need a focused agent review? See AI agent testing.
