About

Professional summary

I am an AI Engineer and Full Stack Developer with experience building production web applications, APIs, and AI-powered systems using Python, FastAPI, React, and React Native.

I specialize in developing RAG pipelines, including PDF ingestion, document cleaning, embeddings, semantic search, prompt engineering, and LLM integrations. I also build streamed API experiences and chat interfaces for real-world AI applications.

My background in full-stack development helps me connect AI capabilities with reliable backend services, responsive user interfaces, relational databases, authentication, payment integrations, and third-party APIs.

I value understanding how an application behaves before making changes, identifying root causes, and producing clean, documented, testable solutions. I have experience improving performance through SQL optimization, caching, and rendering improvements.

I am comfortable deploying and maintaining services on Linux servers, containerizing applications with Docker, and automating internal processes and data workflows with Python and external APIs.

I am interested in joining small teams with real ownership and strong engineering practices. I am particularly drawn to opportunities in education, healthcare, fintech, startups, crypto, and financial markets.
