experience
05/2022 - now: Software Engineer, Risk Management, Zalopay.
- Added distributed rate-limiting to the decision engine using the hit rate of a policy, preventing large-scale incidents from happening while deploying new policies.
- Added rules dependency analyzer to the decision engine, minimizing duplicated method executions and improving performance.
- Added back-filling mechanics to the data ingestion engine utilizing Spark, reducing the time to deploy new policies from several days to a few hours.
- Added feature history tracking, allowing snapshots of production features to be made for analytics and backup.
- Added feature access monitoring, enabling the team to track frequently read/write features.
- Added feature lineage tracking, allowing the team to track the origin of features.
- Improved the distributed configuration synchronization system, reducing storage space usage and the latency of distributing new configurations.
- Simplified the configuration process for the data ingestion engine, allowing analysts to deploy new policies without the help of engineers.
- Migrated back-end services wrapping Tensorflow/CatBoost models from Python to Java, utilizing existing Java libraries and reducing efforts to maintain additional Python code.
- Identified and resolved issues using Open Telemetry in the context of Vertx’s non-blocking APIs.
- Identified and resolved multiple performance issues involving database table indices and incorrect usages of Vertx’s non-blocking APIs.
- Helped analysts translate business requirements into features and rules that can be run on our decision engine.
04/2021 - 09/2021: Software Engineer Intern, Robert Bosch Engineering and Business Solutions Vietnam.
- Maintained the application for parsing documentation in source files and rendering the results in PDFs. Corrected the rendered page layout and content as requested by the customer.
- Maintained the application that serves customized configurations for Jenkins’ pipelines.
12/2018 - 03/2019: Software Engineer, Thợ Tốt Startup.

activities
2019: Coordinated the workshop “Introduction to Programming in Scratch.”
The workshop was one of many from the “VGU STEM Training Workshops 2019” event, which included workshops for high school students with topics across multiple STEM subjects.
2018: Developed the server in “VGU Robocon: Battle Mining Bot 2018.”
“VGU Robocon: Battle Mining Bot 2018” was a competition held by Vietnamese-German University that provided a playground for building autonomous wheeled robots. Here, teams designed robots to collect various objects on the field whose locations were provided in real time through our server.
