Backend Developer for Authentication API Platform

Hello, My name is Ariel Gelberg, a Full-Stack & Backend Developer with strong expertise in Node.js, PHP, and C#, and hands-on experience building secure, scalable REST APIs, authentication systems, and integrations with third-party services. In recent years, I’ve been developing custom SaaS and CRM platforms, focusing on backend architecture, API design, and cloud infrastructure (Docker, Microservices, Redis, and MongoDB). I have solid experience implementing JWT-based authentication, rate-limiting, and security standards aligned with OWASP principles. I’m confident I can contribute to building a robust authentication API platform — from designing backend infrastructure and intelligent routing to delivering monitoring and admin dashboards. I’m currently available for full-time collaboration and can relocate if needed. You can view examples of my production-grade code and API projects here: https://github.com/ariel11212321 Looking forward to discussing how I can help build and scale your authentication platform.
