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.
Sage Fulcher
Hey I'm Sage! Im a Boston area software engineer who grew up in South Florida. Ive worked at a ton of cool places like a telehealth kidney care startup that took part in a billion dollar merger (Cricket health/Interwell health), a boutique design agency where I got to work on a ton of exciting startups including a photography education app, a collegiate Esports league and more (Philosophie), a data analytics as a service startup in Cambridge (MA) as well as at Phillips and MIT Lincoln Lab where I designed and developed novel network security visualizations and analytics. I've been writing code and furiously devoted to using computers to make people’s lives easier for about 17 years. My degree is in making computers make pretty lights and sounds. Outside of work I love hip hop, the Celtics, professional wrestling, magic the gathering, photography, drumming, and guitars (both making and playing them)

I’m a product-focused engineer and tech leader who builds scalable systems and turns ideas into production-ready platforms.
Over the past years, I’ve worked across startups and fast-moving teams, leading backend architecture, improving system reliability, and shipping products used by thousands of users. My strength is not just writing code — but connecting product vision, technical execution, and business impact.
Alvin Voo
I’ve watched the tech landscape evolve over the last decade—from the structured days of Java Server Pages to the current "wild west" of Agentic-driven development. While AI can "vibe" a frontend into existence, I specialize in the architecture that keeps it from collapsing.
My expertise lies in the critical backend infrastructure: the parts that must be fast, secure, and scalable. I thrive on high-pressure environments, such as when I had only three weeks to architect and launch an Ethereum redemption system with minimal prior crypto knowledge, turning it into a major revenue stream.
What I bring to your project:
Forensic Debugging: I don't just "patch" bugs; I use tools like Datadog and Explain Analyzers to map out bottlenecks and resolve root causes—like significantly reducing memory usage by optimizing complex DB joins.
Full-Stack Context: Deep experience in Node.js and React, ensuring backends play perfectly with mobile and web teams.
Sanity in the Age of AI: I bridge the gap between "best practices" and modern speed, ensuring your project isn't just built fast, but built to last.

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.
