What I'm looking for

I want to build scalable, end-to-end products—shipping reliable frontend/backend features and data pipelines—using modern web and cloud technologies. I’m excited to collaborate across teams, improve code quality, and deliver measurable customer impact.

I’m a Software Engineer who builds end-to-end customer and internal products, from feature design to scalable delivery. At Brarista Ltd, I built and owned a client dashboard for revenue tracking and shipped core chatbox improvements like AI-generated Markdown, chat reactions, recommendations, and a bra-selection quiz.

On the frontend and backend, I primarily work with JavaScript/TypeScript, ReactJS, Chakra UI, and Python with FastAPI. I’ve launched customer-facing experiences such as a quiz sidebar embedded on client websites, personalized product recommendation systems, and a mini chatbox integrated at the product level.

Previously at Zalo (VNG Corporation), I led AutoEDA by wiring Hadoop-based pipelines with Apache Airflow to generate exploratory data analysis reports. I also built data tools for debugging (user/location mining), developed React/Vue + FastAPI analytics apps, and deployed Dockerized microservices on Kubernetes using Azure.
