At OnStak, I led development of AI-driven full-stack applications, including a conversational chatbot using LangChain and Pinecone to provide context-aware responses. I also integrated Shopify and WooCommerce so chatbots could handle customer inquiries, product details, and order interactions.

Previously, I developed Node.js applications and APIs at TechExpert and GoalBytes, working across backend services, databases, and React interfaces. At Highrise Technologies, I supported web application development and identity and access management.
