What I'm looking for

I'm looking to build impactful mobile and backend products where I can shape architecture, solve complex integration problems, mentor engineers, and collaborate across teams to deliver reliable solutions.

At Uber Eats, I defined and implemented Global Quick Add to Cart, a standardized Android architecture that lets users add, update, and remove items across stores and screens with minimal integration effort for multiple teams.

I also led delivery of a backend service and external-facing endpoint for REWE Advice Document, meeting mandatory legal requirements in Germany. I support teams across backend and mobile work as an SME on frameworks, architecture, and implementation complexity.

Across Walmart, iTexico, Stokkur, Pademobile, and Gameloft, I’ve built Android applications, POS systems, Bluetooth libraries, messaging platforms, and developer tooling. I’ve led mobile engineers, mentored Android developers, shaped product scope with clients, and improved engineering practices through architecture, code reviews, and testing.
