What I'm looking for

I'm looking to develop further at the intersection of frontend engineering, data, and banking, building reliable, transparent AI-enabled financial products.

At Deutsche Bank's Merchant Solutions team, I built and shipped React and TypeScript features for transaction pages, settlement reports, payment flows, and KPI dashboards used by corporate merchant clients. I owned changes from refinement through testing, UAT, and release preparation in a regulated banking environment.

I also led key workstreams in a Webpack-to-Vite monorepo migration and created Playwright end-to-end coverage for payment, reporting, and dashboard scenarios. I built reusable React and MUI components and worked with backend engineers on API behaviour and data integration.

At BREWWW, I delivered four production platforms using React, Vue, Next.js, and Nuxt.js, integrating GraphQL and REST APIs and building reusable component systems. I'm pursuing an MSc in Data Analytics, with a thesis on Generative AI in banking merchant services, and I'm interested in reliable, transparent AI-enabled financial products.
