Machine Learning and Artificial Intelligence Consultant | 15 years building AI systems | Head of AI @ Electi
Mission-critical AI and Machine Learning systems fail for two reasons: flawed architecture or flawed implementation. >>> I correct both. Most AI initiatives bleed capital on protracted "transformation journeys" that deliver ambiguous results. My function is to provide decisive intervention. I audit, remediate, and optimize high-stakes ML systems to eliminate systemic risk and engineer tangible performance gains. My practice is focused on three core disciplines: > Systemic Audit & M&A Due Diligence: Forensic analysis of data pipelines, neural networks, and ML solutions to identify and quantify sources of bias, instability, performance degradation, and financial inefficiency. > Risk Remediation & Robustness Engineering: Targeted "deep neural graph surgery" to resolve identified flaws. Re-architecting systems for scalability, security, and predictable performance under operational stress. > Performance & Scalability Optimization: Re-engineering models and infrastructure (Python, C++, CUDA, TensorRT) to maximize computational efficiency, reduce operational latency, and unlock unrealized ROI from existing data assets. Production-Grade Generative AI & LLM Systems: A prototype is not a product. I architect and audit Generative AI systems for deployment in high-stakes environments where accuracy, security, and audibility are non-negotiable. > LLM & RAG Frameworks: Engineering and stress-testing Retrieval-Augmented Generation systems to minimize hallucination, ensure factual grounding with proprietary data, and validate information provenance. > Agentic System Architecture: Designing autonomous agent workflows for the auditable execution of complex business processes. The focus is on creating systems that are reliable, predictable, and aligned with strategic objectives, not just technically capable. > Security & Containment: Implementing the architectural and operat
