Build Errors Preventing Deployment
You try to deploy your app but the build fails with errors. The app might work in the AI tool's preview or development mode, but the production build process finds errors that weren't visible before.
Error Messages You Might See
Module not found: Can't resolve
Type error: Property does not exist
Build optimization failed
ERROR in ./src/
Failed to compile
Common Causes
- TypeScript errors that were ignored in development mode
- Missing dependencies — packages referenced in code but not in package.json
- Import paths that work on your OS but fail on the build server (case sensitivity)
- Environment variables needed at build time but not set in the build environment
- Incompatible dependency versions
How to Fix It
- Read the build error log carefully — the actual error is usually near the top or bottom
- Try running the build command locally (npm run build) to reproduce the error
- For TypeScript errors, fix them one at a time — they often cascade
- Check that all imported packages are listed in package.json
- If a dependency version conflict, try deleting node_modules and package-lock.json and running npm install fresh

Caio Rodrigues
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.**

I've been working at a large software company named Kainos for 2 years, and mainly specialise in Platform Engineering. I regularly enjoy working on software products outside of work, and I'm a huge fan of game development using Unity. I personally enjoy Python & C# in my spare time, but I also specialise in multiple different platform-related technologies from my day job.

Get HelpFrequently Asked Questions
The app works in preview but the build fails. Why?
Preview/development mode is more lenient — it ignores some errors that the production build catches. TypeScript strict mode errors and missing dependencies are the usual culprits.
I have dozens of build errors. Is it fixable?
Usually yes. Build errors often cascade — fixing the first few can resolve many of the rest. A developer can systematically fix them and get your app deploying.
