What I'm looking for

I'm looking for a junior developer opportunity to contribute to innovative projects while continuing to grow professionally and technically.

I've built web and mobile applications for agriculture, flood prevention, pet well-being, and technology career guidance. My projects include ARIS Mobile, a smart-agriculture app with authentication, crop management, and real-time API tracking.

For Flood, I developed an informative web application supporting flood prevention and emergency assistance through educational content, weather information, a chatbot, and dynamic interactions. I also worked on WorkRobot, combining a web application and backend for technology career guidance, quizzes, registration, and career-path recommendations.

I'm focused on front-end development and bring full-stack project experience using React, React Native, JavaScript, TypeScript, Java, .NET, SQL, REST APIs, and Git. I enjoy creating modern interfaces and user-focused features.
