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

Jacek Rozanski
Senior PHP/Symfony developer and DevOps engineer with 20+ years of professional experience, running opcode.pl (web development agency, est. 2004).
Day job: I'm the sole backend developer at merketing company where I own and maintain 11 PHP/Symfony microservices on AWS (ECS Fargate, RDS, S3, CloudFront), handle the full CI/CD pipeline (Bitbucket Pipelines, Docker), and manage monitoring with Sentry and CloudWatch. These services handle high request volumes in production every month.
What I bring to AI-built apps:
- I audit and fix security issues (OWASP methodology), performance bottlenecks, and architectural problems in codebases generated by Cursor, Claude Code, Lovable, Bolt, and v0
- I refactor AI-generated prototypes into production-grade applications with proper error handling, testing, and clean architecture (SOLID, DDD, hexagonal architecture)
- I set up the infrastructure AI tools don't touch: AWS hosting, CI/CD pipelines, automated deployments, database optimization, monitoring, and alerting
- I integrate external services: payment providers, email systems, partner APIs, SSO/auth
Tech stack: PHP 8.x, Symfony, React, Next.js, PostgreSQL, MySQL, Docker, AWS (ECS, RDS, S3, SQS/SNS, CloudFront), Terraform, Supabase. I also use AI tools daily (Claude Code, Cursor) in my own workflow, so I understand both the strengths and the gaps in AI-generated code.
Based in Poland (CET timezone). Available for async work and calls during EU/US business hours.

I build and fix web apps across Next.js, Node.js, and DBs.
Comfortable jumping into messy code, broken APIs, and mysterious bugs.
If your project works in theory but not in reality, I help close that gap.

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.

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.
