I am fully confident to build frontend web app with React. I deeply understand how React works with state, lifecycle, hooks and context. I'm focusing to improve the performance and better experience for users. Not only SPA, I am fully aware of how important SEO is, I built a couple of SSR web app projects with Next.js.
I'm very experienced with GraphQL. I can build a backend as GraphQL api with Node.js and Django, as well as a frontend to communicate each other with GraphQL. I can implement to send and receive a multipart data(eg. image file) with GraphQL.
Node.js and Django
I fully understand how http requet/response works with headers, cors, authorization, and json web authentication. I am very experienced with Node.js and Django to build a backend api or server. I know how to deploy it on AWS with docker or serverless.
I am well aware of AWS service architecture and how to compose it for whatever it needs. I know what the pros and cons of serverless architecture and how to use it. Also, I am used to deploy my apps as containerized using Docker.
Mobile app development
I am very comfortable to build a mobile app with React Native and Native modules if needed in case. I know how to build a React Native app with Xcode and Android Studio with Native modules. I really enjoying to improve the performance and give a solid experience to users.
