Hello, I'm Rolano.👋I'm a DeveloperDeveloperwith 4+ years of experience.I enjoy building apps.
About Me
After completing my Bachelor's in Electronics and Computer Engineering from Vellore Institute of Technology, I pursued a Master's in Computer Science and Engineering at the University of North Texas. My favorite aspect of development is solving complex problems and building intuitive, user-centric experiences that make a real impact.
My core technologies include React.js, Next.js, Node.js, Spring Boot, and PostgreSQL, with expertise in TypeScript, Tailwind CSS, and FastAPI. I'm currently working extensively with AI/ML technologies including OpenAI GPT-4, LangChain, RAG (Retrieval-Augmented Generation), Pinecone vector databases, and Supabase. I'm also experienced with cloud platforms like AWS and Azure, and always enthusiastic about learning cutting-edge technologies.
Outside of coding, I'm passionate about fitness and working out, which helps me stay focused and energized. I enjoy traveling, exploring new places, and trying diverse cuisines. Music is a big part of my life, and I love video games and movies as a way to unwind and spark creativity.
