Conceptual terrain study — inspired by snowboarding
01 — ML Research
Representation learning, tested honestly.
Following a question beyond the obvious answer. My research explores how models learn useful representations of complex behaviour.
Researched self-supervised representations using graph embeddings, contrastive learning and non-Euclidean geometry.
Used the autonomy of my role to investigate emerging methods and experiment with their application to practical problems.
Multimodal contrastive learning is an area of study, not a claim of an implemented or deployed multimodal system.

02 — AI Systems
Human-governed, built to be recovered.
Taking an idea from architecture to an end-to-end demonstration, and making its value clear to the people deciding what comes next.
Designed an agentic solution for organisation-wide use, with persistent state, audit trails and mandatory human-review gates.
Built an end-to-end working demonstration. Presented the core concept, value and scaling approach to senior stakeholders.
Retained to develop a funded internal pilot. Intended scope is not a claim of organisation-wide deployment.

03 — Data & Modelling
From large-scale data to a model you can defend.
Working with large-scale financial data, then connecting analysis, modelling and evaluation to a concrete problem.
Analysed financial transaction data with Python, SQL and Snowflake, and completed two fraud-model optimisations during placement.
Applied feature engineering, hyperparameter tuning and performance evaluation.
Gained experience in GPU compute and batch training; no public throughput or model-performance benchmark is claimed.
