Back to original languageAbout Joan
I am an offensive cybersecurity and custom software development specialist, with over 20 years of experience helping companies protect their systems and build secure and scalable technological solutions.
As a certified ethical hacker (OSCP, OSCP+, CEH, among other international certifications), I detect and fix vulnerabilities before they can become a real risk. Additionally, as a senior developer in Java / Spring Boot, I design and integrate robust, secure, and cloud-ready applications (AWS, GCP).
Services I offer
- Pentesting and ethical hacking (web applications, mobile, and cloud environments)
- Security audits and vulnerability management
- Backend development with Java / Spring Boot
- Secure cloud architecture (AWS and GCP)
- DevSecOps integration in development cycles
- Cyber intelligence and incident response
My goal is for you to have peace of mind and confidence in the technology you use, with solutions that adapt to your business, without unnecessary technical jargon and with measurable results.
