I have been working in software development for nearly 15 years. I started my first job as a mobile application development engineer, but in the recent 10 years ago I have worked in both backend and frontend. Especially the project management segment.During 6 years at Nest Tech VN, I myself have built the company from scratch to have an engineering team who expertise on nodejs, mongodb, aws, vuejs, android and ios both native and cross-platform (react-native).Now the company has more than 20 employees with 3 launched products that I am most proud to tell you guys about.1. Kalpha - Application for meeting up and sharing knowledge. This application was developed by an agency in Indonesia but encountered performance problems when scaling up. Therefore, my team took on this project to improve performance to help respond to more than 100k users and help the company launch in the Vietnamese market. Unfortunately, this startup was run out the funding and has no longer invested in developing and releasing new updates. You can have a look at https://kapha.io2. Oddjob - Application that connects service providers and users. I participated in the development of this application from the moment of creating the idea, analyzing the market and deciding on the features. I manage a team of 8 engineers including backend, frontend web and mobile app to build applications for 2 years. Currently, the application has also fallen into hibernation waiting for more capital to develop - https://oddjob.vn3. Hey English - Application for English learners can learn and practice speaking skills. This is the application my team and I are working on and are extremely passionate about it. I am proud to manage non-technical departments such as marketing, customer service, and academics to launch projects to the market. With limited funding, we have achieved more than 50k users within 12 months. And the active user rate MAU is more than 40% - https://heyenglish.vn
