About Me
A passionate developer with a strong foundation in full-stack development and competitive programming.
Patrick Arganza
Full-Stack Software Engineer
Proficient in React, Node.js, and Express with hands-on experience building RAG systems, vector databases, and LLM integrations. Skilled in implementing secure payment processing with Stripe and deploying scalable, AI-enhanced applications.
Lately, I've been diving deep into AI automation—building and deploying autonomous agents that handle complex workflows end-to-end. Orchestrating multi-model systems with Claude, Gemini, and specialized LLMs to create agents that reason, plan, and execute tasks. From engineering RAG pipelines with semantic search to designing agentic systems with tool-calling capabilities and persistent memory, I'm exploring how intelligent agents can transform traditional applications into adaptive, self-improving platforms.
