What I'm looking for

I seek senior frontend or full-stack roles where I can architect scalable web and mobile apps, work with cloud infrastructure and databases, lead technical solutions, and contribute to collaborative teams.

I am an experienced senior developer with a proven track record delivering frontend and hybrid mobile applications across Angular, Ionic, React and Vue ecosystems. I focus on building reusable UI components, integrating RESTful services, and ensuring maintainable code through Git and Gitflow workflows.

Across several projects I have optimized database performance with PostgreSQL, MySQL and MongoDB, deployed and managed services on AWS (EC2, Cognito), and containerized applications with Docker. I have built PWAs and mobile apps published to app stores, implemented messaging with RabbitMQ, and contributed backend integrations using NodeJS, Django and Java/JSF when needed.

I thrive in collaborative, cross-functional teams where I can solve complex bugs, produce technical documentation, and drive efficient delivery of web and mobile products.
