I led the development team in Vietnam to build and maintain Seller Center, the key source of growth for Global Fashion Group, in all global ventures, including The Iconic, Zalora, Dafiti, and Lamoda.

Seller Center is an eCommerce platform that allows shop owners to manage their product catalog, orders, and financial information effectively.

We built the product based on microservice architecture with a combination of technology stacks, including PHP and Java Spring.

I built and maintained Grab Express, an express delivery platform that provides different services for all delivery needs: Instant and same-day delivery. With lightning-fast service, customers get items right away. With fixed and transparent fares on the app and the web page, customers pay the shippers the exact amount without worrying about surge fees.

With back-end services built with the Go technology stack, the most recent project was to provide optimized routes for multi-stop delivery bookings. The web booking service sends the booking requests to multiple destinations, and requests are handled by the core express service that figures out the optimized routes with the cheapest fare and fastest delivery time. Customers then get the suggested routes on the app and the web page and decide the best deliveries for themselves.

I designed, developed, and maintained the best product in replication technology, SAP Replication Server.

SAP Replication Server guarantees high availability of database systems. We move large volumes of information across networks onto destination servers in real-time with no data loss. The business applications on top of database systems operate reliably with nearly zero downtime whenever disasters happen. We support a variety of databases in the industry, such as Oracle, Microsoft SQL Server, Sybase ASE, IBM DB2, and SAP HANA.

Liquid builds a secure and modern-day cryptocurrency ecosystem for traders and consumers to learn, grow, and leverage the benefits of financial freedom that blockchain technology enables.

I worked in the Tech Operations team, responsible for all Liquid operations. The platform was developed on the Ruby on Rails framework.

One of the recent projects included developing a feature to process multiple fee settings in bulk. Fee settings are the commission rates applied on the exchange transactions going on the platform. I developed the front and back-end parts to allow users to upload a CSV file of fee settings. The application then processes the list of fee settings, validates them, and persists them in the databases.

I designed this online shopping application using a model-view-controller (MVC) architectural pattern and built it on the Java Spring Boot framework.

Clients can access and manipulate products and order information in data repositories distributed on multiple servers. The client's application is split into model and view components on the front-end side. The model corresponds to the business logic: Searching and ordering products and a web page representing the list of products and orders. The back end is decomposed into multiple microservices.

Each service has its domain model and data repository. The services communicate with each other via a Kafka message broker. The front end and back end communicate with each other via REST APIs.

I built this project to demonstrate how to apply reactive streams to handle data from SQS queues using Terraform to manage resources on AWS.

The scripts create 50 SQS queues utilizing specified credentials. The Spring Boot application then publishes and consumes the messages going through the queues and treats them as reactive streams.

To deploy the project to AWS Lambda, users only need to specify the class Lambda Handler in the Lambda function setting. The deployment process is as simple as one single line command: mvn clean package.

This project aims to process MIPS code and produce transformed code that allocates the symbolic registers to actual registers for better performance.

I built this project upon the LLVM framework, allowing it to handle various types of input code: C, C++, and Fortran.

This project creates a simple Spring application to manage quizzes and solutions.

I designed it based on an MVC architectural pattern and enabled it to provide a list of APIs for registering users, logging in, creating quizzes, and submitting solutions accordingly.
