Technical AI Program Lead & Product Manager (Expert-Vetted, Top 1%) who turns founder vision into shipped, production AI — not slideware. Ex-Tesla and Experian, with $400K+ earned and 100% Job Success across 45+ Upwork engagements. What I actually do: - Orchestrate multi-model AI — design and build agentic workflows across Claude, GPT, and Gemini, including MCP-based tool/context setups. Hands-on where it counts, and I direct engineering for the rest. - Wire AI into your real stack — connect models to live business data and systems (CRM/Salesforce, cloud, internal APIs) so outputs are grounded, not generic. - Build with governance in mind — SOC 2 / RBAC-aware deployments, sensible data boundaries, and controls to keep shadow AI in check. - Own delivery end-to-end — scope, sequence, and ship with real PM rigor (Agile/Scrum) so AI initiatives reach production and stay maintainable. Tools & stack: Claude, GPT, Gemini, MCP, Jira, Linear, HubSpot, AWS, and modern web stacks (React, Node.js, Python). Track record: - $400K+ earned on Upwork across 45+ engagements, 100% Job Success - $10M+ in client ARR influenced; 200+ complex projects shipped across e-commerce, healthcare, and logistics - Long-term, repeat client partnerships If you need someone who speaks both founder and engineer and can take an AI initiative from idea to production, let's talk. Also available for full-stack delivery — web & mobile app development, Amazon Seller Central, Shopify, WooCommerce, and WordPress — plus data & BI (Power BI dashboards & reporting) and digital transformation consulting, solo or with my NinjaDev team. Whether you need a senior AI/product lead or an end-to-end build, reach out and let's talk.

I am an AI consultant, software architect, and technical strategist with over 18 years of experience translating advanced AI concepts into practical systems, products, and decision-support tools. My work focuses on applied AI, LLMs, computer vision, machine learning workflows, data systems, and AI-powered digital transformation. I help clients evaluate AI opportunities, design technical architectures, define implementation roadmaps, assess model behavior, and build custom AI-enabled software systems. I hold a Ph.D. from the MIT Media Lab, where my research focused on AI, Bayesian network architectures, sensor fusion, user modeling, and computational storytelling for interactive environments. I also bring a strong interdisciplinary background in artificial intelligence, cognitive science, software systems, and human-centered technology. Core AI services include: • AI consulting and technical strategy. • LLM application design, evaluation, and workflow development. • Computer vision consulting, prototyping, and model evaluation. • AI-powered digital twins, simulation, and scenario-testing systems. • Data pipeline design, BigQuery-based analytics, data streaming, and data governance. • Model training, refinement, evaluation, and technical QA. • Technical specifications, product architecture, and AI implementation roadmaps. • Executive coaching and technical tutoring in AI, Generative AI, computer vision, and machine learning. I am especially strong at bridging strategy and implementation. I can help executives understand what AI can realistically do, help technical teams structure the right architecture, and help product teams translate vague AI ideas into concrete requirements, workflows, and buildable systems. My hands-on technical experience includes Python, PyTorch concepts and model workflows, Java, JavaScript/TypeScript, SQL, C++, C#, Shell scripting, BigQuery, AWS, Node.js, MongoDB, Express.js, and web-based application architecture. I am also currently working through an LLM-from-scratch implementation, similar in spirit to nanoGPT, which gives me a practical understanding of embeddings, attention mechanisms, training loops, loss evaluation, and transformer model code. Recent work includes AI-powered digital twins, pedestrian and traffic simulation, video-based mobility analytics, roadway camera networks, dynamic signage systems, and operational intelligence tools for complex urban and airport environments. Clients typically hire me when they need someone who can combine deep technical judgment, clear communication, and senior-level strategic thinking.
