Sandy Lim

I’m a Senior Software Engineer with 10+ years of experience building AI-powered platforms and enterprise systems, with a focus on healthcare and SaaS integrations.

At Glean (May 2020–present), I led the evolution of core ingestion infrastructure and scaled enterprise integrations—architecting a connector framework for 50+ enterprise SaaS applications and cutting new connector development from 4 weeks to 3 days while achieving 99.9% sync reliability across 1,000+ active connections. I also built an LLM-powered connector generator that creates boilerplate code from OpenAPI specs, enabling new SaaS tool support within 24 hours and reducing human intervention by 50%.

Earlier at Abridge (May 2013–May 2020), I helped scale an EHR integration platform and ambient clinical intelligence engine supporting 250+ health systems, improving clinician workflows and saving clinicians 1–2 hours/day through real-time clinical summarization. I designed HIPAA-compliant audit logging and provenance tracking across EHR write operations so AI-generated notes remain verifiable and traceable, and I expanded multilingual LLM summarization to 28 languages and 55+ medical specialties using NVIDIA NIM/TensorRT.
