Work Experience

WealthPark Co., Ltd.
Remote — Tokyo, Japan
Backend & Data EngineerJune 2022 – Present
  • Served as technical project lead for a team of 6 engineers — owning system design, technical specs, code reviews, and client communication; contributed to the engineering hiring loop to grow the data team.
  • Rescued a stalled MWAA ETL project — decomposed a monolith into 3 independent DAGs, enabling concurrent multi-client ingestion and cutting end-to-end processing from days to minutes while tripling overall capacity.
  • Replaced legacy ingestion with async API calls and dynamic task generation, eliminating out-of-memory failures from 2–3 failed DAG runs per week to zero; introduced idempotent retry mechanisms with active alerting, turning an unstable system into a reliable platform that attracted new clients.
The Software Practice Pte Ltd
Remote — Singapore
Full Stack EngineerMar 2022 – May 2022
  • Redesigned the Login and Registration flows using C# and ASP.NET Core Web API, improving usability and visual consistency.
  • Maintained product stability through ongoing bug fixes and iterative improvements to support a reliable user experience.
