AOP Java Framework for Rapid Application Development at CERN

I developed a framework to speed up CERN applications development and reduce boilerplate code using annotations. The framework provided easy binding for JavaFX controls and accelerator hardware settings and provided visual feedback to the user when hardware settings changed.

Quiz Builder Web API

A RESTful service for a quiz builder app developed using Java, Spring Boot, and PostgreSQL. Employed a TDD approach followed with JUnit for unit tests and Newman (Postman Collection Runner) for integration tests.

Shopping List App for Visually Impaired People

I contributed to developing a mobile app for visually impaired individuals, allowing them to create shopping lists through voice commands leveraging technologies like Amazon Transcribe, React Native, AWS Lambda, and DynamoDB. This collaborative effort resulted in an inclusive app that empowers visually impaired users to independently manage their shopping lists, showcasing my ability to work remotely and utilize innovative technologies for impactful solutions.
