Building a mvp / prototype with TypeScript? Let us review it.
Expert code review for mvp / prototype apps built with TypeScript. We fix TypeScript-specific security gaps, optimize performance, and handle deployment. From $19.
Common TypeScript issues we find
Real problems from TypeScript codebases we've reviewed.
Excessive use of 'any' type
AI tools use 'any' to bypass type errors instead of defining proper types, removing all the safety benefits TypeScript provides.
Missing strict mode
tsconfig.json without strict mode enables sloppy type checking that allows null errors and implicit any types.
Type assertions instead of type guards
Using 'as' casts to force types instead of runtime checks, causing crashes when data doesn't match the asserted type.
Incorrect generic implementations
Overly complex or incorrect generic types that confuse rather than help, making the code harder to maintain.
MVP / Prototype challenges to solve
Key mvp / prototype concerns that AI-generated code often misses.
Identifying what actually needs fixing
Not everything needs to be production-grade for an MVP. The challenge is knowing which shortcuts are acceptable (visual polish, advanced features) and which aren't (security, data loss, broken core flows). Our audit prioritizes fixes by impact.
Security minimum
Even an MVP handles user data. You need authentication that works, data isolated per user, no exposed secrets, and HTTPS. You don't need enterprise-grade security, but you need the basics done right.
Deployment
Your app runs locally but deploying it involves environment variables, domain configuration, SSL, and build optimization. First-time deployment is where most AI prototypes hit unexpected issues.
Error handling
When something goes wrong (and it will), your users should see a helpful message — not a white screen or a raw error. Basic error handling is the difference between 'this app is buggy' and 'something went wrong, please try again.'
What we check
Key areas we review for TypeScript mvp / prototype projects.
Core user flow — does signup to core action work reliably?
Authentication — secure login, session handling, password reset
Data security — user data isolation, no exposed secrets
Deployment readiness — env vars, build configuration, domain setup
Not sure if your app passes? Our code audit ($19) checks all of these and more.

Frequently asked questions
Can you review a mvp / prototype built with TypeScript?
Yes. We regularly audit TypeScript mvp / prototype 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 TypeScript mvp / prototype apps?
Common issues include excessive use of 'any' type and missing strict mode on the TypeScript side, combined with mvp / prototype-specific concerns like identifying what actually needs fixing and security minimum. We check for all of these and more.
How do I make my TypeScript mvp / prototype production-ready?
Start with our code audit ($19) to get a prioritized list of issues. For TypeScript mvp / prototype projects, the typical path is: fix security gaps, address mvp / prototype-specific requirements, optimize TypeScript performance, then configure deployment. We provide a fixed quote after the audit.
How long does it take to audit a TypeScript mvp / prototype?
Our code audit delivers a full report within 24 hours. For TypeScript mvp / prototype projects, we check security, architecture, performance, and deployment readiness across all TypeScript-specific patterns. Fixes are scoped separately with a fixed quote.
