Harry Wang is a software engineer with eight years of experience building full-stack systems and infrastructure, currently contributing to AI search and creator-facing features at Meta/Instagram. He combines backend expertise (Express, Flask, ASP.NET Core, Hadoop) with modern front-end skills (React, Vue, CSS) and practical database work across MongoDB, PostgreSQL and Elasticsearch. His internships at NetEase and Xiaomi produced production-facing tools—from a 1000x faster Elasticsearch query for millions of records to a Kythe-based AOSP code visualizer used by 100+ engineers—demonstrating a focus on developer productivity and scalable search. Harry also has experience in infra engineering at The Trade Desk and teaching CS labs at UIUC, reflecting both system-level rigor and an interest in mentoring.
