Work Experience

Senior Software Engineer / Delivery Lead at Samsung

January 1, 2022 - October 1, 2025

Designed and scaled event-driven OCR/NLP services on AKS and Azure Functions to 120+ docs/min with p95<500 ms through batching, model/runtime optimization, and autoscaling; increased end-to-end throughput 30% and cut manual QA hours 22%. Led API-first delivery (FastAPI) with typed SDKs, versioning, and templates; reduced downstream integration time from 5 days to 3 hours and enabled reuse across two DX programs with zero additional platform work. Implemented CI/CD with GitHub Actions and MLflow-backed release artifacts, canary deploys, and runbooked rollbacks; lowered model/service drift incidents from 6/quarter to 1/quarter and reduced mean rollback time ~ 2h → 15m. Built full-fidelity observability (structured logs, metrics, traces) with SLOs and error budgets; improved on-call MTTD/MTTR and stabilized latency during peak ingestion via caching, connection pooling, and backpressure-aware queues.

Software Engineer (Backend & Platforms) at Sony AI

September 1, 2020 - December 1, 2021

Productionized layout-aware classification/NER services in PyTorch+FastAPI with 99.9% uptime and p95 420 ms; enforced latency SLOs using async I/O, connection pooling, and read-heavy caching. Shipped an automated evaluation harness with slice metrics and CI gates; prevented regressions through canary releases and auto-reverts, raising critical-slice F1 from 0.84 to 0.90. Containerized training/inference images and standardized environments; eliminated drift across staging/production and cut cold-starts 35%, accelerating safe rollouts and incident recovery.

Software Engineer at Shopee

April 1, 2019 - August 1, 2020

Built resilient data APIs for financial analytics in Python/Node.js with idempotent jobs, retries, and circuit breakers; improved data sync lag from 15m to 90s across microservices handling million+ transactions. Automated reporting/validation with schema checks and anomaly detection; reduced data-quality incidents 40% and shortened month-end close by ~6 hours. Implemented structured logging/metrics and alerting with on-call runbooks; decreased MTTD 45% and improved SLA adherence on nightly pipelines.
