Hi! I’m Sebastian Vargas, although in the professional world many know me as Johan. I’m a Systems Engineer with 5 years of experience in software development, specializing in creating efficient and tailored solutions. My passion for technology has led me to master a diverse set of tools, ranging from application development to process analysis and optimization across different industries.I have worked with technologies such as Angular, React, Ionic, JavaScript, Python, SpringBoot, LangChain, PHP, Node.js, RxJS, SQL, and NoSQL, as well as frameworks and design styles like Bootstrap, Tailwind, Material Design, PrimeNG, and MDB.One of my most significant achievements was improving the performance of a pension system by creating cross-functional modules and reusable utilities. These solutions not only optimized the efficiency and scalability of the original system but were also replicated in other projects, making a positive impact across the organization. Additionally, I optimized service consumption with reactive programming, preventing memory leaks, which contributed to enhanced system stability and performance.Recently, I have been delving into topics related to neurotechnology, data science, and artificial intelligence, particularly in the creation of AI agents. I have explored advanced techniques like RAG (retrieval-augmented generation) and embeddings, applying them to enhance search and generate more accurate responses in language models and recommendation systems.My approach has always been to deliver innovative and efficient solutions that not only meet established objectives but exceed them.I am open to new collaboration opportunities and exchanging ideas on emerging technologies, data science, and software development.
