Specialties:
Healthcare AI: I am an expert in healthcare AI, with a unique background that blends clinical understanding from my MD, deep technical expertise from my AI PhD, and business experience. I have completed 100+ engagements across medical specialties including radiology, plastic surgery, orthopedic surgery, dermatology, cardiology, mental health, family medicine, dentistry, physical therapy, women’s health, pediatrics, nutrition, and neurology. I have created datasets and custom models for diverse forms of biomedical data including x-rays, CTs, MRIs, clinical photographs, patient videos, medical audio, medical notes, EHR data, insurance claims, omics data, and more.
Computer Vision: I create custom AI models for 2D images, 3D images, and videos on proprietary datasets. I am excited about projects from multiple industries including healthcare, manufacturing, automotive, and agriculture. I have extensive experience with classification, object detection, segmentation, and keypoint detection, to identify and localize abnormalities or features of interest. I developed the first machine learning model in the world to predict multiple abnormalities simultaneously from a CT scan. For a dermatology practice, I built the first CV model to predict Fitzpatrick skin type, pigmentation, redness, and wrinkle severity (mean accuracy 85%)—now a core model at Kesty AI.
Artificial Intelligence R&D: I have led multiple AI research projects across industry and academia. I have developed novel AI methods, including HiResCAM, a convolutional neural network explanation method with mathematical guarantees. I have published original research across multiple areas of AI, including computer vision, natural language processing, explainable AI, expert systems, and applied AI. My research papers have been cited over 1,000 times. My healthcare AI blog Glass Box has over 700,000 readers from 185 countries.
Natural Language Processing (NLP): I have a deep understanding of large language models (LLMs) like Claude, Gemini, ChatGPT, and Llama. I have leveraged Transformers and other NLP techniques for numerous applications, including customized chatbots, medical note generation, and structured information extraction.
Advising Entrepreneurs: Before focusing on AI consulting, I spent seven years as the founder of a health AI startup. I led my previous company from concept to deployed B2B SaaS product serving medical practices. Our AI history-taking assistant and AI scribe saved clinicians 2+ hours daily. I managed engineering teams of 5-10 (60+ contributors), secured two U.S. patents, and raised competitive grant funding. I enjoy working with entrepreneurs and discussing pitch decks, fundraising, customer discovery, designing an MVP, and evaluating the ROI of an AI product.

AI Engineer | Agents, LLM Systems & Full-Stack | Expert-Vetted (Top 1% on Upwork) | Published Researcher (WWW '26)
I build AI systems that ship — not chatbot demos. I've developed AI prototypes for a Fortune-50 entertainment company, co-authored peer-reviewed research on AI agent behavior with Columbia and Yale (accepted to The Web Conference 2026), and have a patent in filing for a novel AI application. For the past 1.5 years I was the sole customer-facing engineer at an AI R&D firm, taking projects from whiteboard to working product.
Most "AI products" disappoint because of poor planning, overreliance on foundation models, and no measurement of whether the system actually works. My approach is different: I scope honestly, design evals before features, and build systems that generate revenue or unlock capabilities that weren't possible before.
What I work with daily:
- AI/LLM systems: agent architectures, MCP integrations, RAG, evaluation frameworks, fine-tuning, LangChain/LangGraph, multi-provider deployments (Anthropic, OpenAI, Google)
Python (15+ yrs): FastAPI, PyTorch, pandas, asyncio — from data pipelines to production APIs
- Cloud: AWS Certified ML Engineer; Docker/Kubernetes; microservices and pragmatic monoliths
- Frontend: React/Next.js + TypeScript (6+ yrs), real-time interfaces with WebSockets
- Rust: systems work, parsers, embedded applications
My process starts on paper: I map the problem, document the plan, and deliver code your team can actually build on — with documentation that explains why, not just what.
If you need someone who knows what's possible with current AI capabilities, how to deliver it, and how to stay within budget — let's talk.
