👤
Senior오경식 Oh is a results-driven CTO with 8+ years building high-traffic consumer platforms, currently leading Lookpin’s technology strategy for a 6.5M-user men’s fashion app. He designs cross-functional systems that tie engineering work directly to business KPIs—improving ROAS/CPI with marketing, raising click-to-purchase rates with merchandise teams, and cutting infrastructure costs by ~40% through architecture and ops optimizations.

Known for instituting developer productivity improvements (Jira/Confluence automation, GitHub Actions CI/CD, Datadog/ELK observability) he combines product empathy with operational rigor. Based in Seoul, he blends pragmatic engineering with measurable business impact and a knack for turning infra savings into growth levers.
