Looking to develop a robust, scalable, and above all, completely secure web application against digital threats?
As aComputer Engineerspecializing inFull Stack Developmentand **Cybersecurity**, I help companies and startups build high-quality digital products, ensuring security and efficiency from the first line of code. My goal is for you to launch technological solutions without worrying about performance failures or security breaches.
- Secure Full Stack Development:Design, development, and optimization of robust web platforms and APIs using modern technologies such asNode.js, PHP (Laravel), React, Next.jsand relational databases (MySQL, PostgreSQL).
- DevOps and Cloud Infrastructure:Automation of workflows (CI/CD) and container management withDockerandKubernetesto ensure fast, stable, and efficient deployments.
- Cybersecurity Auditing and Pentesting:Preventive vulnerability assessment and penetration testing (usingBurp Suite, MetasploitandNmap) under the international standard CVSS v4.0to secure your systems.
Unlike a traditional developer, I bring a hybrid approach based on three pillars:
- Clean and scalable code:Designed underSOLIDprinciples and optimal architectural patterns.
- Active Cybersecurity:Security hardening and vulnerability analysis integrated from the first line of code.
- DevOps Automation:Continuous integration and deployment (CI/CD) philosophy in every phase of the lifecycle.
