What I'm looking for

I am looking for opportunities to innovate in AI, collaborate with talented teams, and drive impactful projects.

I am a results-driven AI Developer with a decade of experience in architecting intelligent systems. My expertise lies in large language models (LLMs), NLP pipelines, prompt engineering, and retrieval-augmented generation (RAG). I have a proven track record of leveraging OpenAI APIs, LangChain, and vector databases like Pinecone to create scalable AI-powered applications that enhance productivity and decision-making for enterprise and SaaS clients.

In my current role as a Senior AI Developer at Pivotking LLC, I architected an enterprise-grade AI assistant platform utilizing GPT-4, LangChain, and Pinecone. I designed modular FastAPI microservices for document management and built LangChain-based agent workflows for various data sources. My strategic technical leadership has driven successful design sprints and architecture reviews, ensuring high-quality AI solutions.

Previously, I led the development of a proprietary RAG framework at ShipMonk, integrating advanced AI technologies for internal compliance use cases. My experience spans from building reusable Python pipelines to automating data workflows, all aimed at optimizing AI performance and user experience. I am passionate about pushing the boundaries of AI technology and continuously improving my skills in this dynamic field.
