WHY ME:
Active penetration tester I know how attackers think
️ Real production experience with modern stacks
Clean, documented, maintainable code
Clear communication throughout the project

PREMIUM PACKAGE INCLUDES:
A full OWASP Top 10 audit with CVSS-scored findings report the same methodology I use professionally for enterprise clients.
WHAT I NEED FROM YOU:
- Clear project requirements or feature list

Veelgestelde vragen
What information do you need to start the project?
A clear description of your project, any design references or wireframes, your preferred tech stack (or I can recommend one), and any existing code or assets. The more detail upfront, the smoother the build.
What technologies and frameworks do you work with?
Frontend: React, Next.js, TypeScript. Backend: Node.js, Django, FastAPI. Databases: PostgreSQL, MongoDB, MySQL. I also work with REST/GraphQL APIs, OAuth, JWT, Stripe, and most major third-party integrations.
Do you provide source code and ownership?
Yes — you receive full source code and complete ownership of everything I build. Code is delivered clean, well-commented, and ready for further development by you or your team.
What does the security audit in the Premium package include?
A full OWASP Top 10 review, secure HTTP headers configuration, dependency vulnerability scanning, authentication and authorization analysis, and a professional findings report with CVSS scoring and prioritized remediation. Same methodology I use for enterprise clients.
Can you work on existing projects, or only new builds?
Both. I can build from scratch, add features to existing projects, fix bugs, refactor code, or perform security reviews on your current codebase. Just share what you have and I'll assess scope.
What if I need changes after delivery?
Each package includes a set number of revisions. Beyond that, additional revisions are $30 each. For longer-term peace of mind, the "30 Days Bug Support" extra covers any bugs found within 30 days after delivery.
Will my application be responsive and production-ready?
Yes. All projects are built mobile-first, tested across devices and modern browsers, and deployed with production-grade configuration. Security headers and basic hardening are applied by default, even on the Basic package.
What's the difference between you and other Fiverr developers?
I'm an active penetration tester in addition to a full-stack engineer. Most developers learn security as a checklist; I find vulnerabilities for a living. That mindset is built into every line of code I deliver — your application launches harder to attack from day one.
