Data Engineer
Aug 2024 - Present
Built ETL pipelines and CI/CD deployment scripts to centralize financial instruments data processing from multiple sources using Amazon Web Services and Java Spring Boot, deployed on Kubernetes, and used by major downstream applications company-wide.
Enhanced a highly concurrent FastAPI Python application for data reconciliation to maintain data quality across 100+ tables, reducing runtime of data quality scripts from 3 days to 4 hours per run, enabling checks to run multiple times daily instead of weekly.
Developed a Python tool to parse requirement specifications and automate code generation.
Developed a full-stack web application as an internal tool for production support.
Tiktok Singapore
Frontend Engineer
Jul 2023 - Aug 2024
Created and maintained a React webpage embedded in TikTok App used by millions of monthly active users.

Some examples are Customer Account Search, General Ledger and Cash Denomination user interface.
Build testable front-end code by using jest and react-testing-library, performing above KPI (80%) with 98% of unit test line coverage score via Sonarqube static code analyzer.
From times to times, performing tech lead duties such as code review, distribute workload to team members, act as technical representative in software design meetings and production support.
Serve as a mentor to new software developers in the team.
Micron Technology
Production Engineer
Nov 2020 - Jul 2021
Led and supervised 9 team members to maximize production line performance and efficiency in order to meet daily wafer production target
Use SQL and Tableau to build an interactive dashboard which automate daily production line performance reporting
Projects
Exploration Agent Based on Pure Visual Cue
Dec 2025
Developed a vision-only reinforcement learning agent for autonomous indoor exploration using CLIP-based intrinsic novelty rewards, enabling navigation-like behavior without depth, pose estimation, or explicit task objectives
Implemented a compact PPO-based architecture with a frozen ResNet-18 encoder and sliding-window Transformer, demonstrating that lightweight models (~3.2M parameters) can learn stable exploration strategies in visually rich 3D environments
Conducted extensive architectural and reward-function ablations (local vs sliding-window attention, random vs PCA projections, curiosity removal), revealing how intrinsic motivation and temporal modeling shape emergent exploration behaviors
