About Me

I am a mathematically rigorous Data Scientist specialising in agentic AI systems and end-to-end machine learning pipelines. My work bridges theoretical mathematics, statistical learning, and practical business impact, consistently delivering functional autonomous systems within 8–12 weeks.

I have extensive experience with AWS and Google Cloud platforms, deploying scalable ML solutions using SageMaker, Vertex AI, and serverless frameworks. My focus is on optimising performance, reducing costs, and translating complex data and algorithms into tangible business results.

Key Areas of Expertise:

Agentic AI & autonomous system design

Statistical learning theory & optimisation

Monte Carlo simulations, DCF, and decision-theory frameworks

Risk algorithm design & scenario-based evaluation

Cloud-native ML architectures and pipeline deployment

MCMC model training & continuous retraining

Failure prediction, anomaly detection, and machine vision

Model validation, A/B testing, and performance monitoring

💻 Skills & Tech Stack

Python | Lean | Ruby | TensorFlow | AWS | Google Cloud | Microsoft Power BI | Git | Docker | LaTeX
