About
Hi, I’m Rajatir Ole, a full-stack (MERN) developer with 5.2 years of experience designing, developing, and deploying scalable SaaS and enterprise applications. I specialize in building cloud-native solutions on AWS, leveraging services such as Lambda, S3, RDS, and CloudFormation, and I have strong experience with microservice-based architectures, REST and GraphQL APIs, and efficient front-end development with React.js.
I thrive in Agile environments and enjoy tackling complex problems with modern tooling. I’m actively exploring Generative AI applications, including Python, FastAPI, Retrieval-Augmented Generation, and embeddings to build AI-powered features with LLM integration and semantic search, while maintaining a focus on security, scalability, and maintainability.
