At CodeExpedition, I build scalable RESTful APIs, backend services, and LLM-powered applications using Python, Node.js, OpenAI, and Anthropic.

I design RAG pipelines for document ingestion, embeddings, vector retrieval, context enrichment, and LLM responses. I also use LangChain and LlamaIndex to deliver semantic search, knowledge retrieval, and AI automation.

Previously at DevsInc, I helped modernize Rails applications, optimize database performance, improve APIs, and build Python automation tools. I contributed to a 40% productivity boost, a 30% query-performance improvement, and a Rails 5-to-7 migration.

Across web, eCommerce, gaming, and customer-engagement products, I focus on reliable services, clean architecture, secure integrations, and maintainable code. I’ve containerized microservices with Docker, deployed on AWS, and reduced deployment downtime through GitLab CI and GitHub Actions.
