I'm a passionate Senior Mobile Engineer with over 8 years of experience specializing in React Native. My journey in mobile development has taken me through diverse fields such as education, insurance, healthcare, logistics, and e-commerce. I thrive on creating responsive, high-performance user interfaces and delivering top-notch mobile applications for both Android and iOS platforms. In addition to mobile development, I also have strong skills in web development using React.js and Next.js.

I have been involved in various challenging and innovative projects, contributing to a diverse range of mobile applications (React Native). This experience has enabled me to further hone my skills and take on significant responsibilities, including:

• 🛠️ Designing Robust Architectures: Leading the design and structure of application architectures to ensure scalability, maintainability, and high performance.
• 🎨 Transforming Designs into Reality: Translating user flows, wireframes, mockups, and prototypes into responsive user interfaces (UIs) with modular, reusable, and high-performance implementations.
• 💻 Developing High-Quality Code: Writing clean, efficient, and maintainable code for both Android and iOS platforms, adhering to best practices and coding standards.
• 🔍 Ensuring Code Quality: Conducting thorough code reviews, implementing automated testing, and ensuring the overall quality and reliability of the codebase.

At Cosmart, I am a member of the initial app development team, where I design the architecture and structure of the application, translate user flows and prototypes into responsive UIs, and develop high-quality code for both Android and iOS. I collaborate closely with product designers, managers, and my team to build innovative features, ensuring the quality of the source code through thorough reviews. My skills in CI/CD, Zustand, Fastlane, and Firebase are pivotal in delivering a successful product.

At Jago Coffee, I maintain and enhance the app, revamp the UIs, and create high-quality code while experimenting with new features alongside product designers and managers. My expertise in CI/CD, Fastlane, Firebase, and Cloud Firestore ensures a smooth development process.

For Diri Care, an online health and beauty clinic app, I designed the app's architecture, developed high-quality code, created MVP and post-MVP features, and revamped the mobile UIs. This project showcased my ability to deliver efficient and user-friendly solutions.

The Avoskin app, an e-commerce application for skincare products, benefits from my design and maintenance efforts, providing customers with an easy-to-use platform for their purchases.
