Full-Stack Dev | React, Node & AI Integration (Claude/OpenAI)

Most AI features and web apps demo beautifully — then fall over the moment real users, real data, and real traffic hit them. I build the part that has to actually hold up in production. I'm a full-stack engineer with 4+ years shipping SaaS products — much of it on security and identity platforms for enterprise-scale organizations, where reliability and access control were never optional. I pair that backend discipline with hands-on AI integration: RAG, tool-calling agents, vision, and LLM features wired into real products.
