Joseph Freeman

I am a senior full-stack engineer with five years building high-performance web and backend systems and three years leading AI/ML initiatives in NLP, semantic search, AI agents, and RAG architectures.

I design and deploy production-grade solutions — from real-time RAG pipelines with LangChain and Pinecone to conversational agents using Claude-3.5 and GPT — optimizing systems for cost and performance.

My engineering work spans FastAPI backends in Python, modular Next.js/React frontends with real-time audio/video and ElevenLabs TTS, Redis caching and pub/sub integrations, and CI/CD with GitLab pipelines and Docker.

I focus on measurable business impact through scalable architectures, robust data pipelines (scraping, cleaning, chunking, embedding), and pragmatic leadership that reduces costs and improves deployment consistency.
