Subbusainath Rengasamy

I’m a Senior Software Engineer and Cloud Architect specializing in Google Cloud Platform (GCP), distributed systems, and multi-cloud architecture. I architect scalable cloud-native systems across AWS and GCP, integrating backend engineering, data platforms, and Generative AI into production environments.

I designed and implemented an end-to-end AI Voice Proctoring MLOps pipeline—covering data ingestion, preprocessing, model training workflows, CI/CD automation, real-time inference, monitoring, and observability. I also work on Large Language Models (LLMs) and production-grade AI/LLM platforms, including RAG, vector databases, and AI agents.

My work spans real-time and batch data engineering pipelines, ETL/ELT workflows, and event-driven architectures handling structured and unstructured data at scale. I focus on performance optimization, reliability engineering, cost efficiency, and observability to deliver secure, highly available systems.

Previously, I built and optimized distributed serverless backends and data-driven platforms at CommentSold, Redgrape, and antstack.io. I operate at the intersection of Cloud Architecture × Data Engineering × Generative AI × MLOps × Backend Systems × DevOps, leveraging tools like ChatGPT, Claude, and LLM APIs to accelerate development and improve engineering productivity.
