Bolt deployment

Blank Page After Deploy to Vercel/Netlify

Your app works perfectly in development but shows a blank white page after deploying to Vercel or Netlify. No errors in the browser console, just whitespace.

The deployment log shows 'Build succeeded' but the page won't render anything.

Error Messages You Might See

Build output exceeded maximum size Error during Next.js build Cannot find module '@/components' Hydration mismatch between server and client
Build output exceeded maximum sizeError during Next.js buildCannot find module '@/components'Hydration mismatch between server and client

Common Causes

  1. Build fails silently but deploy continues - check build logs carefully
  2. Environment variables missing in deployment platform
  3. Node version incompatibility between local and deployment
  4. CSS/images not bundled properly in build
  5. JavaScript runtime error in root component during hydration

How to Fix It

Check full build logs in Vercel/Netlify deployment: look for warnings and errors

Add environment variables in deployment platform settings that exist in local .env.local

Test production build locally: npm run build && npm run start

Check browser DevTools Network tab - are CSS and JS files loading?

Look for hydration mismatches in console warnings

I specialize in rescuing broken Lovable/Bolt/Cursor builds and taking them to production. 10+ apps shipped including SaaS CRMs, gaming platforms, real estate tools, and Discord bots. Stack: Next.js 16, TypeScript, Tailwind CSS, FastAPI, PostgreSQL, Prisma. I use Claude Code with 50+ custom skills for rapid delivery. Average turnaround: 2-4 weeks from broken prototype to production.

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).

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.** Costea Adrian Costea Adrian Embedded Engineer specilizing in perception systems.
