LLM Serving Architecture · Accelerator Scaling (TPU/GPU) · Hardware-Software Co-Design
I am an ML Systems Engineer and Researcher at Google Cloud, working at the intersection of LLM serving architecture, compiler runtimes, and distributed accelerator infrastructure. My work focuses on co-designing serving stacks and multi-node accelerator systems to push the latency–throughput Pareto frontier of frontier models across TPUs and GPUs.
At Google Cloud, I lead inference optimization initiatives for Gemini across GPU and TPU fleets—including architecting intra-node disaggregated serving for air-gapped Sovereign Cloud deployments on Google Distributed Cloud (GDC)—and drove multi-cube interconnect scaling, collective communication microbenchmarking, and Day-1 model enablement for TPU v7 (Ironwood) (Google Cloud Tech Impact Award, 2026).
Prior to Google, I was an Applied Scientist at AWS, where I architected Generative AI root-cause analysis for Apache Spark at hyperscale (Amazon Q) and active verification systems for cloud network security. I earned my Ph.D. in Electrical & Computer Engineering from Carnegie Mellon University (advised by Vyas Sekar and Anthony Rowe, CIT Dean’s Fellow) and previously built distributed edge-AI and IoT systems at Microsoft Research (FarmBeats, DeepEdge). My research spans 15+ publications at venues including SIGCOMM, NSDI, and USENIX Security, and 2 US patents.
Production Systems & Technical Scope
Gemini Serving Architecture & Sovereign Cloud Infrastructure
Google Cloud · 2025–PresentEnd-to-end latency, KV-cache efficiency, and runtime bottleneck optimization for Gemini models on GPU and TPU clusters. Spearheaded the intra-node (4:4 split) prefill/decode disaggregated serving architecture on bare-metal nodes for Google Distributed Cloud (GDC), resolving strict memory isolation and control-plane constraints in air-gapped environments.
TPU v7 (Ironwood) Multi-Cube Scaling & Day-1 Enablement
Google Cloud · Tech Impact Award 2026Architected the NPI microbenchmarking and continuous regression suite bridging internal Borg clusters and Cloud XLA/JAX runtimes. Modeled ICI/DCN collective communication limits across multi-cube topologies and delivered Day-1 third-party model optimization (Llama 3, DeepSeek) for tier-1 frontier AI evaluations.
Hyperscale Distributed Diagnostics & Network Verification
AWS · 2023–2025Architected and launched LLM-driven automated root-cause analysis (Amazon Q) across AWS Glue and EMR, reducing Spark job failure resolution from days to minutes, alongside high-throughput synthetic traffic validation for cloud network ACL compliance.
