I built the ABCs of LinkedIn Jobs.

• Abuse Prevention: enabled trusted job marketplace with three-pronged protection, including online prevention, offline detection, and community report

• Billing Pipeline: bookkept delivered value for jobs by metering spend through impression, click, and conversion attribution, while enforcing daily and lifetime budget caps

• Campaign Foundation: powered job auction and delivery with automated bidding, budget-aware pacing, and qualified candidate targeting

While launching these initiatives, I was recognized with "Best Execution Award Finalist" and "Best Code Contributor Award," and strove to foster team accountability and improve engineering excellence.

• Founded Jobs Trust team, scaled it from one man army to a full-stack team of 10 engineers within 3 years, and led the team as Tech Lead Manager

• Chaired Data Model Review Committee to perform mandatory review of all data models, including schemas for REST API, Kafka event, and database

• Championed system design interview for LinkedIn Jobs, mentored 9 engineers, and hosted 2 interns (both converted to full-time)

At Samsung MNO Lab, I focused on prototyping solutions for the Internet of Things, smart home, and connected car using artificial intelligence and mobile computing technologies. These innovations have generated multiple patents, won "Best Proposal Award" at Samsung Mobile Developer Conference, and been commercialized into Samsung products.
