Hi everyone,
I’m excited to join the DEV community.
I’m currently learning and building around web development, AI tools, SaaS ideas, and software security. My main interest is helping beginners and non-technical founders understand how to build apps faster, but also make sure they are safe before launch.
I’m also working on a project called VibeSafe, focused on making app security easier to understand in simple language.
I’m here to learn, share my journey, ask questions, and connect with other builders, developers, and founders.
A few things I’m interested in:
- AI-built apps
- Web app security
- SaaS tools
- No-code and low-code apps
- Beginner-friendly development tips
- Startup and product-building lessons
I’m looking forward to learning from this community and sharing useful things along the way.
What is one beginner-friendly security tip you think every new app builder should know?

Welcome! Great to have you here.
For your question: never trust user input — even if it comes from a form, API, or file upload. Always validate, sanitize, and use parameterized queries to prevent SQL injection.
If you're building AI-powered apps, also watch for prompt injection — users can trick your LLM into revealing system instructions or data.
For beginners, I'd also recommend OpenSparrow — a self-hosted PHP/PostgreSQL platform that generates CRUD apps from JSON config. It's built with security in mind: parameterized queries, session hardening, CSP, and audit logging out of the box.
Good luck with VibeSafe!
