    ✅TOP ELITE WEB AND MOBILE APP DEVELOPER with a keen eye for details Before talking about qualifications and professional abilities, I would like to introduce myself. I am Godstime Obasi. Taking web development as a profession not only fulfills my pocket but also my heart because it has been my passion since my early teenage and have worked with companies like Uber and Facebook DevC. I believe that people should do things in which they are good at or in which their hearts lay. That’s why I chose freelance web development as my career because I believe I’m good at this, I am always honest and I am never afraid of doing hard work. I am an expert in using both ReactJS and NodeJS. I also know the use of React Native and Flutter for iPhone, iPod, Android, and Tablet. I have developed various websites to optimize their search engines and to create easier user interfaces. Some of the skills I've developed over the years include: ★ NodeJs/Express ★ Databases (MySQL, MongoDB, Firebase) ★ ORM/ODM (Mongoose, Sequelize) ★ ReactJs/Redux ★ VueJs ★ Php/Laravel ★ Wordpress ★ API Integration ★ React Native ★ CSS/Scss/Sass ★ DevOps (Docker and Heroku) ★ Microservices (Nodejs) ★ Bootstrap ★ Material designs ★ Tailwind CSS ★ Responsive design (for mobile and web) ★ Cross-browser compatible design (including IE 7,8 and Safari) ★ UX/UI design I am sure that if you hire me, I will present to you many successful projects with minimal efforts from your side.

    As a former software engineer/manager at companies like Apple, Amazon, Microsoft, Uber, and several fast-growing startups, I've experienced firsthand the challenges development teams face when it comes to staying aligned, being productive, and ensuring on-time project deliveries. The constant need to keep everyone on the same page can be a real pain point. That's why I founded CodeSync-to simplify collaboration for development teams by using AI-generated coding summaries. Our goal is to help dev teams, managers, and stakeholders stay in sync with clear, concise updates on code progress. -- What is CodeSync AI? -- CodeSync AI de-risks your project and sprint deliveries through accurate status updates, based off of real coding activity. It provides leading indicators of project success, improves developer focus time, and saves 2-3 hours that each developer spends per week on routing status updates and sync meetings. Augment your daily standups with AI-generated coding summaries.
