For five years Jonathan André Guevara Layme has been building backend services and web applications for a public institution of more than a thousand employees, and the numbers have started speaking for him. Strong in Java and Spring Boot —REST APIs, microservices and hexagonal architecture— and in Angular 17, React and TypeScript on the frontend, he delivers features end to end: from design through deployment and support.
His most talked-about feat is an AI-powered case-law search engine: he vectorized the entire body of rulings and built a chatbot that answers questions about them in plain language, using Ollama, embeddings and RAG. Query time fell from roughly fifteen minutes to under one second. Also his is SIGEF, the flagrancy management system deployed across more than ten courts.

Sources close to the developer confirm he is in his final year of Software Engineering at UTP (class of 2026), that seven of his systems are formally approved by Administrative Resolution, and that one of them was adopted by the Superior Court of Justice of Moquegua. He plays piano in his spare hours.
