Acerca de este Servicio

Looking for a modern, high-performance website that actually works the way it should?

I build full-stack web applications and business websites using React, Next.js, and FastAPI (Python) a modern, reliable stack that scales well beyond a simple template site.

What sets me apart: I also work as a security researcher (HackerOne, Intigriti), so every site I build is developed with secure coding practices baked in from the start proper input validation, safe authentication, and no common vulnerabilities left behind for someone else to find later.

What you get:

Clean, responsive design that works on all devices

Fast-loading, well-structured code (not bloated page-builder output)

Custom backend functionality when you need it databases, APIs, admin dashboards, user accounts

Clear communication throughout the project

Code that's secure by default, not as an afterthought

Whether you need a simple landing page or a full web application with a database and user logins, I'll build it properly the first time.

Message me before ordering if your project has custom requirements happy to scope it out together.

Cybersecurity researcher & full-stack web developer with hands-on experience finding real vulnerabilities on live platforms through HackerOne and Intigriti. I specialize in web application security testing IDOR, authentication/authorization flaws, GraphQL security issues, and OAuth/config misconfigurations combined with the ability to actually build and fix the applications I test. As a developer, I build modern full-stack applications (React/Next.js frontends, FastAPI/Python backends, PostgreSQL, Docker) so I don't just report bugs, I understand how to properly remediate them too.
