Software engineering for regulated, high-scale systems

Himanshu Gaur

I design and build highly concurrent backend systems and scalable data infrastructure for the pharmaceutical and healthcare industries. I specialize in architecting solutions that handle massive scale while strictly adhering to complex compliance frameworks like HIPAA, GDPR, and SOC 2.

Currently a Senior Software Engineer at ProcDNA, my work spans multi-tenant microservices, zero-ETL data pipelines, and processing terabytes of production data. Recent milestones include engineering a social listening platform with a self-serve analytics layer, developing a search product utilizing Elasticsearch and ClickHouse, and rebuilding data isolation architectures from the ground up for EU market expansion.

I work primarily with Go and Python on AWS, leveraging infrastructure-as-code and modern orchestration. Increasingly, I help clients integrate Generative AI, LLMs, and agentic workflows into their core platforms, ensuring these ML components are reliable and secure in heavily regulated environments, not just functional in a demo.
