Full-Stack AI Engineer | RAG | LLM | MVP

Most software problems are not really coding problems. They are architecture problems that show up months later as a rewrite, a scaling wall, or a system nobody can maintain after the original developer leaves. I design systems that hold up. I build AI, backend, and infrastructure that stays accurate, scalable, and well documented long after the project ships. You work directly with me. I own the architecture, the code, the deployment, and the documentation. What I Do: - AI & ML: Artificial intelligence and machine learning products. RAG systems, chatbots, and LLM prompt engineering, backed by vector databases for retrieval. - Backend & APIs: Python with Django and FastAPI. GraphQL APIs, and RabbitMQ for async and event-driven work. - Web: React and JavaScript front ends on top of those APIs. - Cloud & DevOps: AWS development including AWS Lambda, Google Cloud Platform, and Azure DevOps. Docker and DevOps pipelines for repeatable deployments. - Big Data: Pipelines and processing for large data sets that feed the AI and analytics work. 10+ Years of Production Python: Since 2015 I have shipped production code that scales. I know which architectural decisions hold up at Series A and which ones cost a full rewrite. Tell me what you are building and what is breaking, and I will design the system that fixes it.
