Senior mobile engineering engagement supporting the development and launch of the BeOne mobile app for a crypto-focused platform. Worked across launch-critical product journeys such as customer onboarding and account entry; addressed mobile application security concerns, including secure user flows and authentication-related behavior, and protection of sensitive app data. Diagnosed and resolved issues across an existing React Native codebase while delivering new functionality in a fast-moving launch environment, collaborating across product requirements and UX.

Worked on internationalization of MyArtBroker’s digital marketplace using AI and Next.js to create locally relevant user experiences. Developed and tuned an AI-powered translation and localization workflow capable of transforming large volumes of website content for global audiences (including artwork, artist portfolios, and broader site content). Focused on localization quality (natural, purpose-built writing per market rather than literal translation), integrated AI workflows into the Next.js production environment, and iterated on AI behavior to improve contextual accuracy, consistency, and overall customer experience.

Built customer-facing web products using React, Next.js, TypeScript, and Node.js; delivered high-performance applications across desktop, mobile browser, and hybrid application environments. Improved scalability, monitoring, and testing practices; defined elements of release/development process. Helped migrate functionality from a monolithic Java backend into smaller Node.js services and supported production Java platform transition. Built reusable libraries and frameworks to improve engineering productivity and code quality.
