Contributed to migrating the legacy Vue.js web application to React with TypeScript and MobX, improving performance, maintainability and the overall user experience. Developed and maintained the React Native mobile application so site teams could access project information, tasks and report statuses directly on site. Worked closely with foremen and other end users to refine workflows and increase visibility into production phases for site teams.

Started the migration from an existing Angular-based frontend towards React, reimplementing key desktop features as React views and using Redux to keep application state predictable in a complex business domain. Implemented new features and improvements alongside the migration work, helping the product evolve while the technology stack was being modernised. Supported the introduction of TypeScript into the codebase to catch issues earlier and improve overall code quality and maintainability.

Implemented server–client communication (data transfer, authentication) using PHP on the backend and Java on the Android client. Developed the web interface for the warehouse management system, including backend endpoints and the browser UI with JavaScript.
