I'm Cristian Perez, a Full-Stack Developer, AI Engineer, and Data Analyst based in the Dominican Republic with 6+ years of experience building modern digital products — from polished user interfaces to intelligent, AI-powered systems.
I specialize in creating scalable, user-focused applications across the full stack using React, Next.js, Angular, TypeScript, Node.js, NestJS, and GraphQL. In recent years, I've expanded deep into AI engineering — building intelligent applications, automation pipelines, custom chat agents, and LLM-powered tools using frameworks like LangChain, OpenAI API, Anthropic Claude, and the Model Context Protocol (MCP).
I also bring a strong foundation in data analysis, using Python, Pandas, Matplotlib, and Tableau to uncover insights and support smarter business decisions.
What makes me different:
- ⚡ Strong frontend engineering with deep backend capabilities
- 🤖 Real AI product experience — not just prompting, but building
- 📊 Data-driven thinking baked into every solution
- 🎯 Clean code, maintainable architecture, and genuine business value
