Grosu Marian George

I'm a freelance Full Stack & Blockchain Developer based in France and the founder of AlfaNest Labs. Beyond software development, I specialize in end-to-end technical and security audits for complex web platforms. My work goes beyond code review—I evaluate the entire system, including frontend, backend, APIs, authentication, authorization, payment flows, AI integrations, infrastructure, and overall application architecture to identify security, operational, and design risks. I've performed comprehensive assessments for enterprise-grade platforms, including multi-jurisdiction legal technology solutions, reviewing every critical component from user flows and access control to business logic, compliance considerations, and production readiness. On the development side, I build secure web applications, business platforms, APIs, Web3 and custom solutions using TypeScript, Node.js, React, Next.js, Solidity, and EVM-compatible blockchains. Security is part of the development process from day one—not something added at the end. I enjoy working on existing codebases, understanding complex systems, improving architecture, and delivering solutions that are secure, maintainable, and built for long-term growth.
