• Led a full-stack project of building up a website page of a self-service platform for the clients to visually design and purchase their own merch, using HTML, SCSS, Angular, and TypeScript/JavaScript for frontend interface and graph customization mockup, using Python and OpenCV to process images combine and using Python Flask and PostgreSQL to handle RESTful API calls and store data on the backend. Resulting in a user base increase of 14% (200 users).

• Self-designed, developed, and implemented a site traffic page (including URL-shortener, traffic source distribution graph, etc.) to the main platform product website to complete the UTM optimization via Python Flask and Memcached, enabling a significant shorter responding time (by 20%), reloading period, and getting a boost in redirect traffic (50% increase) from various social media platforms (Tiktok, Instagram, YouTube, etc.).

• Created and implemented a synchronized API in the main product backend using Python multi-threading method, enhanced the shopping cart checkout feature from the original version, shortened the average checkout time by 20 seconds (reduced by 60%), and decreased the abandoned checkout cart rate by 20%.

• Led a team of 8 developers, worked with different functional teams (design, product, operations team, etc.) to develop a fully functional social network website with Angular and Ionic (prioritizing tasks, multi-tasking, managing several development goals with project management skills), and enabled 5000+ users to own, create, and join private spaces with highly protected privacy and security.

• Managed client expectations and document business requirements by daily meeting with the CEO and management team. Provided suggestions for improvement of the frontend and backend.

• Designed, architected, and wrote the frontend of the company’s web applications, including private space creation on the digital map displayed on the main page, utilization of location service embeds in the operating system and browser, and private space management page using HTML, CSS, Angular, TypeScript/JavaScript, and Express with 12 different web pages and 500+ reusable components.

• Implemented and updated 20 RESTful API services in the backend to support the creation, update, and participation of private spaces and store, management, change of data generated by users within the company’s main product via JavaScript, Node.js and Redis as backend and MongoDB as database.

• Designed the baseline test of the neural machine translation with Python. Improved the quality of translation while applying Real-Time Interactive Text Steganography in the generation process.

• Used Tensorflow and Pytorch to build a RNN (Recurrent Neural Network) model and realized hiding bitstream in the translation that generated from the model

• Designed and developed test tools, platforms, and automated tests with Script Language, C++, and PHP for Baidu’s Mobile App which has over 150 million users.

• Built a front-end UI using React, Bootstrap, jQuery, and HTML with 5,000 lines of codes to make the test system more interactive.

• Responsible for related product requirements analysis, use case design, testing, and test progress.

• Developed and maintained efficient continuous integration, unit testing frameworks and tools for development teams, improve code quality and development efficiency by 10%

• Proposed product improvement suggestions based on the reviews to enhance user experience.
