I am a professional engineer and team manager. I have 7 year's experience in mobile app development using native(Swift/Java) and react-native. And I have developed a wide range of websites using JS framework, MEAN stack and HTML/CSS, including sites for startup companies and small businesses. My major areas are Swift, React-native, Laravel and MEAN stack(MongoDB, ExpressJS, AngularJS and Node). When developing the backend, I prefer going with MEAN stack. I am interested in building quality software. I will write code well designed, easy to understand, maintain and extend in the future by using test-driven development. ★ Best Quality and Accurate Deadline. ★ Good Responsive and Perfect Communication Skill. ★ Pixel Perfect UX/UI design. Look forward to working with you. Best regards.
