Web App Development & Fixes

Transform AI-generated web applications into professional, scalable products. We fix ChatGPT prototypes, Copilot code, and no-code exports to create web apps that actually work in production.


The Web App Problem

AI can build a working demo in hours, but production web apps need more:

  • Scalability - Handle thousands of concurrent users
  • Security - Protect against attacks and data breaches
  • Performance - Load in under 3 seconds
  • Reliability - 99.9% uptime without crashes
  • Maintainability - Easy to update and extend

We bridge the gap between prototype and production.


What AI Gets Wrong

Security Holes

Common Issues:

  • Hardcoded API keys and secrets
  • No input validation
  • Missing authentication
  • Exposed admin endpoints
  • SQL injection vulnerabilities

Our Fixes:

  • Environment-based configuration
  • Comprehensive input validation
  • JWT or session-based auth
  • Role-based access control
  • Parameterized database queries

Performance Problems

Common Issues:

  • Loads all data at once
  • No caching strategy
  • N+1 database queries
  • Unoptimized images
  • No lazy loading

Our Fixes:

  • Pagination and infinite scroll
  • Redis caching layer
  • Query optimization
  • Image compression and CDN
  • Code splitting and lazy loading

Poor Architecture

Common Issues:

  • Everything in one file
  • Mixed concerns (UI + logic + data)
  • No error handling
  • Hardcoded values everywhere
  • No tests

Our Fixes:

  • Clean folder structure
  • Separation of concerns
  • Comprehensive error handling
  • Configuration management
  • 70%+ test coverage
