I’m Alexander Suhhin, a Senior Fullstack Engineer with 20+ years of experience building secure, high-performance backend systems and cloud-native platforms. I design robust authentication flows, real-time APIs, and modular front ends, with hands-on work in Node.js, TypeScript, GraphQL, AWS, and AI integrations.
