Juan Bojaca

I’m a Senior Full Stack Developer with a passion for building scalable, reliable, and forward-looking applications. My experience spans across React.js, Vue.js, and Node.js on the frontend and backend, along with enterprise development using Java (Spring, Spring Boot, Hibernate) and Python (Django). In addition to full stack development, I bring practical expertise in AI and large language models (LLMs), working with frameworks and tools such as Claude, LangChain, LangGraph, and vector search systems to design intelligent, context-aware applications. I’ve applied these technologies to real-world products, integrating conversational AI, retrieval-augmented generation, and custom pipelines. I’m also experienced in blockchain development, building decentralized applications and secure smart contracts. A strong advocate of Test-Driven Development (TDD), I focus on writing clean, maintainable, and high-quality code. I enjoy mentoring teams, solving complex problems, and leveraging emerging technologies to deliver impactful, future-ready solutions.
