Practice an applied AI system design interview with me playing the interviewer. We'll choose a scenario relevant to your target role, such as a RAG application, an AI assistant, or an agent that uses tools. One 90-minute live session — $225 total, one-time. First 60 minutes: Clarify requirements, sketch the architecture, and explain your decisions. I'll press on data flow, retrieval, model selection, evaluation, latency, cost, permissions, failure handling, and monitoring. We'll focus on the tradeoffs that matter for the scenario. Final 30 minutes: Feedback on your architecture, reasoning, and communication, followed by preparation priorities. You'll leave with your design notes and specific areas to improve. Before we meet, send your target role, interview date and stage, experience level, and any shareable description of the interview format. Purchase this offering, then message me with a few times that work before your interview. We'll confirm a time in Leland messages. I've worked in AI since 2015. I'm an NVIDIA DLI Certified Instructor, and my AI research includes collaborations with researchers from Stanford, Johns Hopkins, and the University of Pennsylvania.

I help candidates prepare for AI and ML roles with technical, behavioral, and hiring-manager mock interviews. Technical sessions cover Python, NumPy and pandas, ML fundamentals, RAG and retrieval evaluation, agent tool calling and evaluation, and AI system design. For behavioral and hiring-manager rounds, we'll practice role fit, project deep dives, impact, teamwork, and stakeholder communication using examples from your real experience. I've worked in AI since 2015 and am an NVIDIA DLI Certified Instructor for Building Agentic AI Applications with LLMs and a University Ambassador. I have a Ph.D. in Computer Science and experience as a Data Scientist at the University of Pennsylvania. My AI research has included joint collaborations with researchers from Stanford, Johns Hopkins, and the University of Pennsylvania, including multimodal machine learning for human wellbeing and audio-visual prediction and explanation. At Utah Valley University, I teach applied AI and develop learning resources on LLMs, generative AI, model evaluation, and responsible AI. I lead technical work on DataGovAI, a multi-agent RAG project for government records-retention compliance with the Utah Office of Data Privacy. I have also delivered NVIDIA DLI workshops at UVU and the University of Utah. Selected app case studies • AI-ClassSims: Co-PI and technical contributor on multi-agent classroom simulation for teacher preparation. • CareWise: Developer and technical lead on a citation-grounded caregiver-information research prototype. • Willow: Built a no-login demo and chat-stability fixes for a streamed LLM reflection-companion prototype.
