Backend and Full-Stack Developer focused on secure architecture and production delivery. I build systems end-to-end: backend design, APIs, database layer, real-time features, deployment, and containerization.

• Backend: Node.js, REST API, WebSocket, JWT/session flows
• Frontend: TypeScript, React, Next.js
• Databases: PostgreSQL, MySQL, MongoDB
• Security: secure coding, threat modeling, attack surface reduction
• AI: LLM API integration, workflow automation, assistant logic
• Infrastructure: Docker, Linux, Git, containerized deployment

• Part-time and freelance roles
• Full-Stack development (React / Next.js + Node.js backend)
• AI integration and automation tasks (LLM-powered product features)
• Security-focused engineering work (secure APIs, auth hardening, threat-aware architecture)
