Image Upload Failing or Corrupted in Lovable
When users try to upload images in your Lovable app, the upload either fails entirely, succeeds but the image appears broken or corrupted, or the image uploads but never displays correctly on the page.
Image uploads are a core feature for many apps — profile pictures, product images, gallery uploads. When they break, users can't complete essential tasks and the app feels unreliable.
The issue may appear in different ways: a spinner that never completes, an error message after selecting a file, a broken image icon where the photo should appear, or images that upload fine on desktop but fail on mobile.
Error Messages You Might See
Failed to upload image
Payload too large
Error: new row violates check constraint
The resource could not be loaded
net::ERR_FAILED 413
Common Causes
- File size too large — Mobile phone photos can be 5-15MB, exceeding default upload limits
- Wrong MIME type — HEIC images from iPhones aren't handled, or the server expects specific image formats
- Storage bucket not configured — Supabase storage bucket doesn't exist or has wrong permissions
- Missing image transformation — Images aren't resized before upload, causing timeout on large files
- Base64 encoding issues — The app converts images to base64 for database storage, hitting text column size limits
How to Fix It
- Check Supabase storage configuration — Verify the bucket exists, is set to public (if images need to be displayed), and has correct RLS policies
- Add client-side image compression — Use a library like browser-image-compression to resize images before upload
- Handle HEIC format — Add HEIC to JPEG conversion for iPhone users using heic2any library
- Increase upload size limits — Configure your server and Supabase to accept larger files if needed
- Verify the image URL — Check that the stored URL is correct and accessible by opening it directly in a browser

I am a technologist and product builder dedicated to creating high-impact solutions at the intersection of AI and specialized markets. Currently, I am focused on PropScan (EstateGuard), an AI-driven SaaS platform tailored for the Japanese real estate industry, and exploring the potential of Archify.
As an INFJ-T, I approach development with a "systems-thinking" mindset—balancing technical precision with a deep understanding of user needs. I particularly enjoy the challenge of architecting Vertical AI SaaS and optimizing Small Language Models (SLMs) to solve specific, real-world business problems. Whether I'm in a CTO-level leadership role or hands-on with the code, I thrive on building tools that turn complex data into actionable value.

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.

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
Why do iPhone photos fail to upload?
iPhones save photos in HEIC format by default, which many web apps don't support. You need to either convert HEIC to JPEG before upload or configure your storage to accept HEIC files.
Should I store images in the database or storage?
Always use dedicated storage (like Supabase Storage or S3). Storing images as base64 in the database is slow, expensive, and hits size limits quickly.
