My AI-Built App Is Really Slow
Your app takes forever to load, pages are slow to navigate, or actions (like saving data or loading lists) take several seconds. It was fine at first but got slower as you added more features.
Common Causes
- No pagination — the app loads all data at once instead of in chunks
- Missing database indexes on commonly queried columns
- N+1 query problem — the app makes hundreds of individual database calls instead of one
- Large unoptimized images loading on every page
- Unnecessary re-renders in React causing the UI to lag
- No caching — every page load fetches everything fresh from the database
How to Fix It
- Open browser Network tab and see how many requests are made and how long they take
- Add pagination to any list that could grow beyond 50 items
- Optimize images — compress them and use lazy loading
- Check the database for missing indexes on columns you filter or sort by
- If the API is slow, check how many database queries each endpoint makes
Real developers can help you.

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.**

Get HelpFrequently Asked Questions
The app was fast at first but now it's slow. Why?
Usually because the database has grown and the app wasn't built with pagination or indexing. AI tools rarely optimize for scale.
Can a developer speed up my AI-built app?
Yes. A developer can add pagination, optimize queries, add caching, and compress assets. These are standard performance fixes.
