Modals and Popups Cut Off on Small Mobile Screens
Modals, popups, and dialog boxes in your Base44 app are unusable on mobile devices. The modal content extends beyond the screen with no way to scroll, action buttons at the bottom are hidden below the viewport, and users can't complete the action the modal was designed for.
Modals are used for critical interactions in Base44 apps: editing records, confirming deletions, viewing details, and filling out forms. When they're broken on mobile, users are stuck and can't complete core workflows.
The issue is especially bad on smaller phones (iPhone SE, older Android devices) and when the device keyboard opens inside a modal form, shrinking the visible area to almost nothing.
Error Messages You Might See
Submit button not visible on mobile modal
Cannot scroll modal content on phone
Modal form fields hidden behind keyboard
Modal extends beyond screen boundaries
Common Causes
- Fixed height exceeding viewport — Modals have a fixed height (e.g., 600px) that exceeds small phone screens (667px or less)
- No internal scrolling — Modal content doesn't scroll, so content below the fold is permanently hidden
- Centered positioning ignores viewport — CSS centering with transform places the modal partially off-screen on short viewports
- Keyboard pushes modal up — When the keyboard opens for form inputs, the modal shifts up and the top is cut off
- Padding consuming too much space — Large padding inside the modal wastes valuable screen real estate on mobile
How to Fix It
- Use max-height: 90vh with overflow-y: auto — Limit modal height to 90% of viewport and make the content scrollable
- Make modals full-screen on mobile — Below 768px, switch modals to full-screen sheets that cover the entire viewport with proper scrolling
- Stick action buttons to the bottom — Use position: sticky; bottom: 0 on the button row so it's always visible regardless of scroll position
- Reduce padding on mobile — Use smaller internal padding (12px instead of 24px) on screens below 640px
- Handle keyboard appearance — Use the Visual Viewport API to adjust modal position when the keyboard opens

Solo dev shipping production apps with AI-assisted development. I specialize in rescuing broken Lovable/Bolt/Cursor builds and taking them to production. 10+ apps shipped including SaaS CRMs, gaming platforms, real estate tools, and Discord bots. Stack: Next.js 16, TypeScript, Tailwind CSS, FastAPI, PostgreSQL, Prisma. I use Claude Code with 50+ custom skills for rapid delivery. Average turnaround: 2-4 weeks from broken prototype to production.

Full-stack professional senior engineer (15+years). Extensive experience in software development, qa, and IP networking.
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.

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 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.

Get HelpFrequently Asked Questions
Why can't I see the buttons at the bottom of my Base44 modal on mobile?
The modal height exceeds the phone's screen height and the content isn't scrollable. Add max-height: 90vh and overflow-y: auto to the modal, or make buttons sticky at the bottom of the modal.
Should I use modals at all on mobile?
For simple confirmations, modals are fine. For forms with multiple fields, consider navigating to a full-page form on mobile instead of using a modal. This gives users more space and avoids keyboard issues.
