Slow Page Load Times in Base44 Application
Pages in your Base44 application take a long time to load, sometimes several seconds or more. Users see loading spinners for extended periods, and the app feels sluggish compared to native websites. This is causing user drop-off and complaints.
Performance issues tend to worsen over time as more data accumulates in the database and more components are added to pages. What started as a fast app during development becomes increasingly slow in production.
The slowness may affect all pages uniformly or be concentrated on specific pages that display a lot of data, have many components, or make multiple API calls.
Error Messages You Might See
Common Causes
- Pages load all data from a large table without pagination or lazy loading
- Multiple API calls are made sequentially instead of in parallel when the page loads
- Large images are not compressed or resized, adding megabytes to the page load
- Too many components on a single page, each making their own data queries
- No caching is configured, so every page visit fetches fresh data from the database
How to Fix It
Start by identifying which pages are slowest using the browser's Network tab in developer tools. Look for the largest requests and the longest-running queries.
If data tables load all records, implement pagination or limit the initial query to a reasonable number (25-50 records). This alone can dramatically improve load times.
Compress and resize images before uploading them to Base44. Use the browser's Lighthouse tool to get specific performance recommendations. For apps requiring significant performance optimization, a developer can restructure data loading, implement caching, and optimize queries.

15+ years shipping production infrastructure for startups. Former CTO at qed.builders (acquired by The Sandbox).
Cursor ambassador and agentic tooling builder.
I've scaled systems, automated deployments, and built observability tools for AI coding workflows. I specialize in taking vibe-coded apps from broken prototype to production-ready: fixing Supabase auth/RLS, Stripe integrations, deployment pipelines, and cleaning up AI-generated spaghetti.
I build tools in this space (agentprobe, claudebin, micode) and understand both sides: how AI generates code and why it breaks.

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.

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)

Jacek Rozanski
Senior PHP/Symfony developer and DevOps engineer with 20+ years of professional experience, running opcode.pl (web development agency, est. 2004).
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). Available for async work and calls during EU/US business hours.

Get HelpFrequently Asked Questions
Why is my Base44 app so slow?
Common causes include loading too much data without pagination, uncompressed images, and too many components making individual data queries. Use the browser's Network tab to identify the bottleneck.
How do I speed up data loading in Base44?
Implement pagination to load only 25-50 records at a time instead of the entire table. This is the single most impactful optimization for data-heavy pages.
Does Base44 support caching?
Check Base44's documentation for caching options. At minimum, you can optimize by reducing redundant data fetches and loading data once for components that share the same data source.
