Vercel, Railway, Heroku, VPS deployment failures

AI-generated apps (Lovable, Bolt.new, Cursor, Replit)

API integration errors (REST, webhooks, Stripe, etc.)


COMMON PROBLEMS I FIX DAILY:

"Module not found" / build errors

API returning 400/401/500 errors

CORS issues, broken auth flows

App works locally but fails on deployment

Lovable/Bolt app that stopped working after editing

What if your web app could load 2× faster and keep users engaged longer? I help businesses turn ideas into fast, reliable, and scalable web applications that users love. With 2 years of hands-on experience and 20+ successfully delivered projects, I specialize in modern stacks like Next.js, Nest.js, TypeScript, PostgreSQL, MongoDB, Supabase, and AWS. My approach is simple: performance, scalability, and clean code. For example, I recently optimized a Next.js application with server-side rendering (SSR) and AWS hosting, cutting page load times by 50%, which significantly boosted user engagement
