    Thank you for visiting my profile. About myself, I'm a Frontend developer with 7+ years of experience. Have been involved in the development of about 12 Angular based applications. Right from ideation to MVP stage and ahead. I've been working on Angular right from the initial version to the latest one. I can help you by: ◉ Developing an MVP in quick time. ◉ Manage a new project up to delivery and beyond. ◉ Update or fix existing application features. ◉ Discuss and develop a complex UI. ◉ Optimizing existing Angular application. I can also help in converting your Angular apps to PWAs thereby adding features like push notifications, installable on mobile home screens and offline availability. My cloud skills include implementing CI/CD pipelines, deployments & scaling the application. Ionic, React Native, Git, Node, Java, Spring Boot, Docker, Kubernetes, Jenkins, AWS, and Linux are some other skills that I'm also hands-on with. Good communication is very important in building the right product, so let's connect to discuss!
