Hire the Best Stanford CoreNLP Specialists

Top 1% Expert-Vetted Freelancer. I am a physician scientist (MD/PhD) and expert in healthcare AI and deep learning. My MD, PhD in Computer Science, and prior 7 years as a Founder/CEO give me unique insights into clinical workflows, technical implementation, and business considerations. I build healthcare AI systems that go from idea to working prototype in weeks—from computer vision models for clinical images, to NLP systems for medical documentation. I leverage my experience to deliver results efficiently. I send clients initial modeling results 3x faster than typical industry timelines—typically 3 to 4 days after dataset delivery, with 6-8 hours of work required. You’ll get actionable insights in days, not weeks. * After a 30-minute to 1-hour initial meeting, I'll craft a clearly written report outlining a unique AI strategy for your project. * For long-term engagements, I implement AI solutions end-to-end, including data collection, data cleaning, novel model design, model implementation and training in Python, and iteration on the modeling and data strategy to achieve excellent performance. * One of my specialties is creating custom computer vision models for medical images, including radiology images and clinical photographs. I have completed 100+ engagements across medical specialties including radiology, dermatology, cardiology, mental health, family medicine, surgery, dentistry, physical therapy, women’s health, pediatrics, nutrition, and neurology, using a wide range of modeling strategies, from logistic regression to custom deep learning models. Topic Areas: Production Healthcare AI: I founded and led a healthcare AI startup 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 understand not only models, but the entire product lifecycle. Computer Vision: 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 and published in the Journal of Cosmetic Dermatology. I create AI technology for 2D images, 3D images, clinical photographs, and videos. Natural Language Processing (NLP): I have a deep understanding of large language models (LLMs) like ChatGPT, including the nuances of the Transformer neural network architecture that powers LLMs. I have leveraged Transformers and other NLP techniques for numerous applications, including customized chatbots, medical note generation, and structured clinical information extraction. Medical Applications and Digital Health: I am a physician, with an MD from Duke University. I build and clean datasets from scratch and design custom models for any kind of biomedical data, including 2D medical images, 3D medical images, clinical photographs, audio, electronic health records (EHR) data, sensors, and omics data. Explainable AI: I've developed novel techniques that provide further insight into how a model works, such as HiResCAM, an explanation method with mathematical guarantees. Academic Background: I earned my MD and PhD in Computer Science (Machine Learning/Artificial Intelligence) from Duke University with a 4.0 GPA. I have published original research across multiple areas of artificial intelligence, including computer vision, natural language processing, explainable AI, expert systems, and medical applications. Example Projects: Create custom computer vision models to: *Identify abnormalities in medical images (classification) *Localize abnormalities in medical images (object detection, segmentation) *Predict clinical features of patient photographs or videos *Measure or count clinically relevant characteristics in images *Detect body keypoints and identify body positions and clinically relevant angles *Process DICOMs for use with AI *Develop AI solutions for x-rays, CT scans, MRI, ultrasound, clinical photographs, pathology images, and video Create custom natural language processing solutions to: *Chat with users and answer questions *Extract structured information from medical notes or electronic health records data *Analyze sentiment, tone, and reading level *Summarize text Create custom interpretable models to: *Predict patient outcomes like hospitalization or mortality *Identify genes or omics signatures that predict disease Strategy and research projects: *Develop an AI strategy for your organization *Design and execute an original research project in AI *Provide feedback on an idea: Is it clinically relevant? Is it technically feasible? How can you create the dataset? How much data will you need? What modeling strategies should you use? How should you measure performance?

I design and build production-grade security systems for companies that need to secure cloud infrastructure, pass audits, and operate in regulated environments. Most teams don’t have a security tool problem. They have an architecture, integration, and execution problem. That’s where I come in. What I Do I help startups and enterprise teams move from: ❌ fragmented tools and partial controls ❌ audit delays and failing security reviews ❌ reactive fixes and security debt → to ✅ engineered, scalable security architecture ✅ audit-ready, continuously compliant environments ✅ automated, integrated security operations Core Expertise Cloud Security & Cryptography • Multi-cloud security architecture (AWS, Azure, GCP) • TLS PKI systems with automated certificate lifecycle (IaC + CI/CD) • Encryption architecture (CMEK, KMS, data masking, data protection) • Cryptographic hardening aligned with FIPS and modern standards • DNS security, network isolation, and zero-trust patterns Identity & Access Management • SSO (SAML, OIDC), enterprise identity federation • RBAC and least-privilege system design at scale • SCIM provisioning and identity lifecycle automation • Integration with enterprise IdPs (PingFederate, Azure AD, Okta) • Cross-account and multi-environment access control Compliance & Audit Readiness • SOC 2, ISO 27001, PCI DSS, HIPAA, FedRAMP-aligned environments • End-to-end delivery: gap assessment → implementation → audit support • Control design, remediation, and evidence automation (Vanta, Drata, custom pipelines) • Continuous compliance monitoring vs point-in-time audits • Closing audit findings fast (not just identifying them) Security Engineering & Incident Response • CI/CD security (SAST, DAST, IaC scanning, secret management) • Vulnerability management with automated remediation workflows • Cloud misconfiguration detection (CIS benchmarks, runtime analysis) • Secure system design across infrastructure and application layers • Incident response, forensics support, and system hardening AI-Driven Security I don’t just integrate tools — I design security platforms. I have built and architected multi-agent AI-driven cybersecurity systems combining: • Cloud security analysis (AWS integrations, IAM analysis, misconfiguration detection) • Offensive security (recon, exploitation, privilege escalation simulation) • Vulnerability management (SAST, DAST, fuzzing, CI/CD integration) • SOC automation (SIEM/SOAR integrations, alert enrichment, playbooks) • Forensics and incident investigation workflows • Compliance reporting mapped to frameworks (SOC 2, ISO 27001, PCI, HIPAA) Key capabilities: • Multi-agent orchestration and communication • Automated remediation workflows • MITRE ATT&CK mapping and executive reporting • API-driven integrations across security tooling ecosystem • Role-based access for security, DevOps, and compliance teams This enables: → Continuous security instead of periodic assessments → 80% reduction in manual security effort → Faster audit readiness and real-time visibility How I Work • Engineering-first — I build and implement, not just advise • Work directly in production systems (cloud, identity, pipelines) • Design for real audit constraints, not theoretical compliance • Fast execution, clear communication, and ownership Typical Clients • SaaS companies preparing for SOC 2 / ISO 27001 / HIPAA • Cloud-native platforms handling sensitive or regulated data • Startups entering enterprise sales with security blockers • Organizations with fragmented security tools that don’t work together Important I’m not a fit for checklist-based security or surface-level audits. If you need: • real security architecture • working implementations • systems that pass audits and hold up in production - we’ll work well together.
