AI Product Development | Nucleus Institute

Accelerated Product Development | search https: nucleus institute .com I design and build production-ready AI products : on 3, 6, 9, and 12-month contracts. If you're a product developer who needs someone to own the engineering end-to-end, not just write code, but make the right calls; that's what I do. With 10+ years of experience, I've moved fast on hard problems: custom LLM applications, intelligent automation, fullstack AI products across web and mobile, and the infrastructure to run them reliably in production. What I build: Fullstack AI web & mobile apps • Custom LLM integrations • Intelligent automation systems • Data pipelines & model deployment infrastructure AI & ML: LangChain / LangGraph / LangSmith • OpenAI, Claude, Gemini • Hugging Face (fine-tuning, deployment) • TensorFlow, PyTorch • Stable Diffusion, LoRA/QLoRA • Recommendation & generative AI systems Stack: Python, TypeScript, SQL • Google Vertex AI, AWS SageMaker • Nvidia NIMs, Groq • Advanced data processing & feature engineering I don't hand off prototypes. I build things that hold up architected to scale, easy to maintain, and optimized for real-world performance, not just benchmarks. I've also mentored 1,000+ students in engineering, which means I communicate clearly, flag issues early, and never leave you guessing on where things stand. If you're building something serious and need a contractor who moves with urgency, let's talk.
