À propos de moi
I’ve been a Fiverr member since 2012 and recently started offering services actively on the platform, while bringing years of real-world development and infrastructure experience outside Fiverr.
I’m a full-stack developer specializing in scalable, production-ready web applications, SaaS platforms, and CMS solutions using React, Node.js, Laravel, PHP, and PostgreSQL. I also handle server setup, deployment, optimization, and security using NGINX, SSL, and Linux to build fast, secure, and reliable systems for businesses and growing platforms.
