EDUCATIONBachelor of Computer Science Aug 2014 - Sep 2017University of Manchester GPA: GPA: 3.8 of 4.0Studied Program Engineering, Algorithm and Database Management PROJECTSHabitat Website Nov 2022 - Mar 2023The Habitat site is a kind of E-Commerce for furniture in garden, bedroom, living room and cook. It also shows the status and location of delivering members to customer. Depending on functionalities we could divide into purchase part, map view and payment one. To develop this system. we used React.js for frontend and Node.js for its backend. This project is written by TS and used Redux and Redux Saga for its state management and built components using React Hooks. We implemented agile methodology in this project.During the development, I worked as a lead frontend developer with 6 senior and mid-level developers. I always put emphasis on team collaboration and growth in techniques so I discussed the requirements with clients in detail. I divided the tasks to our team members according to skill sets and I also made them share technical knowledge and experience to enhance overall skills. We used Jira and Slack to keep communication between team members. However, when a month was left, the client asked us to finish the project two weeks earlier. I have a good time-management skill so I eliminated meetings and gave developers right directions and necessary books and documents to decrease development time. I also promised two-day PTO after the success of the project. We accelarated development speed, kept communication, finished the web app deployment in 12 days and achieve our goal.Clerked May 2021 - Aug 2021The ClerkedApp is kind of a healthcare app that lets doctors and patients can schedule the meeting, as well as doctors can take care of the patients with detailed information such as blood pressure, temperature, heart rate, etc. It also gives health education and self-care tips and reminders for patients. It also has a chat system that allows doctors and patients could have conversation with text/voice/video chat via DM or Group Chat. So this system has 2 user roles: one is for doctors and the other is for patients Depending on functionalities we could divide into patient detail and meeting scheduling management module (similar as CRM), Health education and follow-up care plan module and chat module. To develop this system. we used React.js for frontend and Node.js for its backend. We used React Native for Android/iOS platforms. This project is written by TS and used Redux and Redux Saga for its state management and built components using React Hooks. We implemented waterfall management methodology in this project. After checking requirements, we designed this system and divided into several milestones and made clear plan for each step. To implement functionalities, we spent about 3 months and for maintenance and testing, we spent about 4 weeks and after that, we deployed this project. While working on this project, I worked as a Senior/Lead frontend developer, so I did mentoring junior and mid-level developers, and I developed and solved several technical issues such as props drilling and long initial load time. I adopted state management system such as Redux and Redux Saga for prop drilling and implemented dynamic import, code splitting and lazy loading for initial load time. As a result, I reduced initial load time by 40% and improved performance by 20%.
