Expert-Vetted (Top 1%) | 100% Client Satisfaction | 100% Job Success I build software that requires rigorous mathematical depth, AI, ML and/or data analytics expertise, and production-ready deployment capability - the combination most teams need three or more separate specialists for. Every system I build goes to production. Deployed solutions running real operations across healthcare, legal, finance, maritime, industrial, and scientific applications. --- ## What Sets Me Apart - Rare Combination: PhD in AI & Systems Engineering + Chartered Mathematician (UK) + 15+ years shipping production systems. I build the ML, and deploy to production - as one person. - Domain Versatility: I've delivered production systems across radically different industries because my depth is in methodology, not a single vertical. Clients hire me when the problem is hard and needs to actually work. - Agentic AI Architect: I design and deploy multi-agent workflow systems that autonomously reason, plan, and execute complex tasks across enterprise domains. - Proven Track Record: 100% client satisfaction on Upwork. Every client has extended, returned, or referred. --- ## Why Clients Choose Me - "We need three people for this" → I'm one person who architects, builds, and deploys. - "Our data scientists can't ship" → Every system I build runs in production. - "This problem is too complex" → I've crossed healthcare, legal, maritime, and industrial domains. Novel problems are my specialty. --- ## Production Deployments (Selected) ### Healthcare & Medical AI - Surgical segmentation system for a US hospital :- ultrasound vein/artery detection deployed on Nvidia Jetson edge device, used in live surgery - FDA 510(k) submissions for AI-enhanced medical imaging :- multiple successful clearances at GE Healthcare - Clinical AI at NHS Barts Health Trust (Europe's largest cardiovascular centre) :- 50,000+ patient records, 88% diagnostic accuracy - Biomarker risk scoring platform :- 28 health dimensions from 118 blood biomarkers, end-to-end from ingestion to reporting ### Legal AI - Case analysis system providing lawyer-grade advice - RAG architecture with case law retrieval, deployed and serving clients in Canada - Document intelligence for contract analysis - 70% efficiency gains for law firm operations ### Maritime & Industrial - Ship fuel optimisation :- ML model identifying optimal ports based on fuel energy content, not just price - 6-hour-ahead location prediction :- real-time forecasting using weather and oceanographic parameters for Gulf of Mexico operations - Industrial process AI :- distillation plant optimisation, hot rolling mill control systems --- ## Technical Depth - AI/ML: PyTorch, TensorFlow, custom neural architectures, transformers, computer vision, NLP, time-series forecasting, optimisation algorithms - Production Systems: AWS/GCP cloud deployment, edge devices (Nvidia Jetson), real-time pipelines, microservices, Docker, Kubernetes - Healthcare Specific: DICOM, HL7 FHIR, EHR integration, biosignal processing, FDA regulatory submissions, HIPAA/PIPEDA/GDPR compliance - Agentic AI: Multi-agent systems, RAG architectures, LLM integration (Claude, GPT-4), Model Context Protocol - Mathematical Foundations: Signal processing, Bayesian statistics, causal inference, control theory - deriving solutions from first principles --- ## Credentials - PhD in AI & Systems Engineering - Chartered Mathematician (UK) - professional certification requiring rigorous examination - 20+ peer-reviewed publications in clinical AI and medical imaging - Multiple FDA 510(k) clearances - Systems deployed to 200+ hospitals --- ## Industries & Applications - Primary: Healthcare & Medical Devices (diagnostic AI, clinical decision support, medical imaging, FDA submissions) · Legal Tech (document intelligence, case analysis, contract AI) · Maritime & Logistics (route optimisation, fuel analytics, predictive systems) · Scientific Computing (biosignal processing, risk modelling, complex simulations) - Secondary: Financial Services (document extraction, risk modelling) · Industrial (process optimisation, predictive maintenance, safety systems) · Aerospace (systems engineering, reliability analysis) --- ## Engagement Model - Rate: $200–300/hour depending on complexity and engagement length - Availability: Selective - I take projects where my expertise genuinely matters - Working Style: Direct communication, clear milestones, results-focused collaboration. --- ## The Bottom Line If it requires AI, ML, data science expertise, and production deployment across a specialised domain - and it actually needs to work - that's exactly what I do. Let's discuss your challenge.

I design and build intelligent systems that automate complex business processes and deliver measurable results. My work sits at the intersection of machine learning, data engineering, and software architecture. Over the past decade I moved from analytics into full-stack AI system development, creating custom agents, LLM-powered automation, and production-ready pipelines for clients in fintech, e-commerce, and education. My approach is straightforward: understand the real problem, design clean data flows, and deploy something that actually works. I have led projects ranging from enterprise CRM migrations and probabilistic modeling for hedge funds to autonomous multi-agent systems for lead generation and language education. These are not prototypes. They run in production and make businesses faster, smarter, and more efficient. I work primarily in Python across FastAPI, LangChain, PyTorch, scikit-learn, PostgreSQL, and modern data stacks like Databricks and PySpark. I build and maintain scalable pipelines, integrate LLMs into real products, and keep everything auditable and reproducible. Clients usually come to me when they have outgrown spreadsheets and patchwork automations and need a clear technical path forward. I like that kind of work. The messy, high-leverage projects where data can actually be turned into something useful. Fluent in English, Russian, and Portuguese.
