OPEN TO OPPORTUNITIES

Python Developer & Backend Engineer

I design and build REST APIs, CRUD services, and database-driven backend systems — with the analytical discipline I built investigating fraud risk at Amazon.

About

From fraud investigation to
backend engineering.

I started my career reading transaction patterns for a living. Now I write the systems that generate, store and serve that kind of data — with the same discipline for correctness I picked up investigating risk at scale.

Investigation-grade attention to detail

Nine months identifying and minimising fraud risk at Amazon, sustaining a 0.0004% defect rate across 15 fraud pattern categories.

Backend-first mindset

Comfortable owning a feature end-to-end: schema design, endpoint logic, validation, error handling and documentation.

Data-literate by habit

Uses Pandas, Power BI and Tableau to sanity-check backend data before it ever reaches a dashboard.

Experience

Where the discipline comes from.

A short, dense record — analytical rigor at Amazon, now channelled into backend development.
