About Me
I’m a Frontend Developer with 3+ years of professional experience
I’m a Frontend Developer with 3+ years of professional experience building modern web and mobile applications using React.js, Next.js, and React Native. I specialize in creating scalable, high-performance interfaces that balance clean architecture, great user experience, and maintainable code.
I’ve worked on fintech and digital payment products, including corporate banking management systems, payment gateway dashboards, e-wallet apps, and merchant applications. My experience covers translating Figma designs into production-ready interfaces, integrating RESTful APIs, handling state management with Zustand/Context and TanStack React Query, and optimizing performance, SEO, and responsiveness.
On the mobile side, I’ve built production-ready Android applications using bare React Native, implementing features such as QR payments, biometric verification, OCR, secure local storage, and multi-environment builds. I’m comfortable working in Agile teams, participating in code reviews, and collaborating closely with backend developers, designers, and product stakeholders.
I’m passionate about writing clean, modular code, continuously improving my skills, and building products that solve real-world problems.
