Top SchoolBoris Lin is a Senior Software Engineer in the San Francisco Bay Area with 11 years of experience building scalable product and serving infrastructure across search, recommendations, and shopping systems at Pinterest. He brings deep backend expertise—refactoring large codebases, improving JSON parsing and iterator patterns, and contributing to the well-regarded Anserini IR toolkit—alongside hands-on experience building distributed data pipelines and ML training data flows. His career blends industry and research: internships and research assistant roles at Facebook, Samsung Research, and the University of Waterloo sharpened his skills in big data, ads measurement, and AR interaction studies. Comfortable across the stack, Boris also ships developer-facing tools and visualization systems, and his attention to code quality and maintainability consistently reduces technical debt. Outside of engineering he pursues photography, a creative counterpoint that informs his attention to detail and product aesthetics.
