Collaborated on Android development using Kotlin. Built user interfaces and worked with APIs and databases. Strengthened problem-solving skills and backend understanding, later applied in data handling tasks for DS projects.

Worked on UI development and REST API integration using Flutter. Gained experience in parsing JSON/XML data — foundational for working with real-world datasets in ML workflows.

Developed full-stack web applications using React.js, Node.js, and MySQL. Experience with data flow between frontend and backend improved my understanding of structured data — useful for analysis pipelines in current DS projects.

Created and managed client websites. First step into programming and understanding how to structure, update, and manage content systems — later supported my transition into backend logic and data-focused development.
