ML/NLP Engineer with 6+ years of experience building and shipping production ML/NLP systems for e-commerce, retail, and developer-tooling platforms. I specialize in production RAG systems and LLM infrastructure - owning projects end-to-end, from architecture and fine-tuning through deployment and stakeholder buy-in. Recent work includes a RAG-based customer-support chatbot (LangChain + in-house LLMs) that cut median messages-to-resolution from 4 to 1 and raised NPS by 15 points, and an internal LLM API platform (FastAPI, Kafka, Docker, Kubernetes, CI/CD) giving 8 product teams secure, real-time access to shared models. I also built a graph-based RAG coding agent that improved benchmark accuracy by 34%, and an NLP trend-detection service that cut root-cause analysis time by 30%. Earlier in my career I productionized computer vision pipelines for manufacturing (TensorFlow, OpenCV - ~10% accuracy gain, ~33% lower inspection cost) and built ML training/deployment workflows on AWS (SageMaker, S3, Airflow, MLflow) to standardize hand-off between data science and engineering. I'm comfortable translating technical architecture for non-technical audiences — I've presented RAG systems and governance models directly to product and legal stakeholders to secure compliance sign-off for production rollout. Domains: E-commerce, Retail/Manufacturing, Developer Tooling 🧠 Core: Python, PyTorch, TensorFlow 🛠️ Infra: Docker, Kubernetes, Kafka, FastAPI, CI/CD, AWS (SageMaker, S3, Airflow) ⚙️ ML/NLP: LangChain, HuggingFace Transformers, MLflow, OpenCV

Work Experience

Machine Learning Engineer at Ocado
April 1, 2024 - Present
Built a customer-support chatbot with LangChain and in-house LLMs over a RAG pipeline, cutting median messages-to-resolution from 4 to 1 and raising NPS by 15 points. Developed an internal LLM API platform in Python with FastAPI and Kafka, containerized with Docker and deployed on Kubernetes via CI/CD, giving 8 product teams secure real-time access to in-house models and cutting duplicated ML engineering work across teams. Launched a machine learning trend-detection service on Kubernetes using PyTorch and an NLP topic model, shipped via CI/CD, surfacing actionable sales and defect patterns for product teams and cutting root-cause analysis time by 30%. Presented the RAG architecture and governance model to product and legal stakeholders across 8 teams in plain, non-technical language, securing compliance sign-off and enabling production rollout.
Machine Learning Engineer at CODE AI
September 1, 2023 - April 1, 2024
Built an MVP machine learning coding agent in Python on a graph-based RAG framework that automated developer code generation, improving accuracy by 34% in engineering benchmarks and establishing the technical foundation for the company's production product.
Machine Learning Engineer at InData Labs
February 1, 2020 - August 1, 2023
Productionized a computer-vision machine learning pipeline (TensorFlow, OpenCV) for a manufacturing client, improving defect detection accuracy by roughly 10% and reducing manual inspection costs by about a third over a six-month rollout. Set up machine learning training and deployment workflows on AWS (SageMaker, S3, Airflow) with MLflow experiment tracking, cutting model hand-off time between data science and engineering teams and enabling standardized, repeatable production releases.
