Modal Dialog Accessibility Issues - Focus Trap Not Working
Modal dialogs aren't accessible. Users can tab to elements behind the modal, keyboard focus isn't trapped, or screen readers don't announce the modal.
Accessibility testing tools flag issues with focus management and ARIA attributes.
Error Messages You Might See
Focus escapes modal to background
Screen reader doesn't announce modal
No way to close without mouse
Keyboard navigation broken in modal
Common Causes
- No focus trap - focus can escape to background content
- Missing dialog role or aria-modal attribute
- ESC key doesn't close modal
- No aria-labelledby or aria-describedby
- Background content not marked inert
How to Fix It
Use accessible modal library: react-modal, headless-ui, or radix-ui Dialog
Or implement: focus-trap package for managing focus
Add attributes: role='dialog' aria-modal='true' aria-labelledby='title'
Close on ESC: window.addEventListener('keydown', e => e.key === 'Escape' && closeModal())
Mark background inert:
{content}

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 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.

Caio Rodrigues
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.**
You don't need to be technical. Just describe what's wrong and a verified developer will handle the rest.

How do I trap focus in modal?
Use focus-trap library or: track focus, when focus reaches last element, move to first (and vice versa)
