Sandhu
Santhakumar.
Technology Architect & System Designer building the backbone of high-stakes digital platforms — distributed systems, cloud architecture, and AI integration engineered with production-grade rigor.
Architecture over artifacts
I'm a Technology Architect and System Designer with 14+ years of experiencebuilding the backbone of high-stakes digital platforms. I specialize in designing distributed systems that are high-throughput, low-latency and — most importantly —maintainable.
I advocate for the clean rewrite when technical debt becomes a liability, and I treat automation as a non-negotiable foundation for any engineering culture. My work spans event-driven microservices, cloud-native infrastructure across AWS, GCP, and Azure, and increasingly, AI platform design — building the integration pipelines and backend orchestration that make Generative AI actually production-ready, not just impressive in a demo.
Right now I'm focused on bridging traditional enterprise system design with the evolving world of AI architecture — ensuring intelligent systems are built with the same rigor we'd apply to any mission-critical backend. Beyond systems, I focus on the engineering environment itself: the guardrails, standards, and automation culture that let teamsscale without chaos.
Code is temporary,
but architecture is permanent.

;What I work on
Distributed Systems
High-throughput, low-latency architectures designed for scale — and engineered to stay maintainable long after launch.
Cloud Architecture
Cloud-native infrastructure across all three major platforms, built with automation as a first-class citizen.
AI Platform Design
Integration pipelines and backend orchestration that make Generative AI production-ready — not just demo-ready.
Engineering Culture
Guardrails, standards, and automation that let teams scale without chaos — plus API security by design.
Selected architecture work
Real-Time Data-as-a-Service Platform
Lead Platform EngineerA large-scale Data-as-a-Service (DaaS) platform that collects, processes, and routes real-time data from multiple sources, delivering sub-second latency while scaling to millions of events per second.
Peaked at several million events/minute during live global events (e.g. Formula 1) — with zero-downtime production deployments via a blue-green strategy.
