Software Engineer, Enterprise AI

Nutanix

Now

Apr 2025 to Present

Building an enterprise RAG product and an agent platform on Nutanix's hybrid-cloud stack.

• Built a RAG application where users ask natural-language questions over their own documents. Handles upload, parsing, chunking, and retrieval end to end, with ChromaDB as the vector store.
• Productionized the RAG pipeline: containerized the services and deployed them on Kubernetes so the full flow runs as a real product, not a notebook demo.
• Building an agent app that exposes MCP servers as tools so users can converse with the agent and get work done across those surfaces.

Software Engineer, FX Graph Compiler (Meta Training & Inference Accelerators)

Meta (MTIA)

Aug 2024 to Apr 2025

Compiler work on Meta's in-house AI silicon (MTIA). Python frontend, C++ backend, and device kernels. Lowering PyTorch graphs down to accelerator-ready code.

• Added compiler passes at the FX-graph level: architecture-based op decompositions, pre/post TorchInductor op decompositions, and tensor broadcasting.
• Lowered 2 IG production models end-to-end onto MTIA silicon. Authored FX-level op decompositions, wrote kernels, and made model-level changes as needed.
• Proposed and shipped support for data-dependent dynamic operators on MTIA, leveraging PyTorch 2.0 Dynamo tracer features to handle shape-dependent control flow.

Software Engineer, Horizon Creator Tools

Meta (Reality Labs)

Jun 2022 to Aug 2024

Creator tooling in Horizon Worlds, Meta's cross-platform metaverse game engine. Work spanned graphics, scripting, and the asset pipeline.

• Delivered Unity Asset Bundles as an ingestible asset format for Horizon (C# + React), enabling scriptable animations, custom shaders, and collisions with native Horizon entities. Grew user retention ~20% by unlocking more expressive worlds.
• Shipped a Unity extension using UI Toolkit that let creators upload UABs directly into Horizon, backed by Hack + GraphQL services for file storage, user validation, and side-effect tracking.
• Co-architected and launched Horizon Templates (Horizon's answer to Unreal Blueprints / Unity Prefabs) in C#, Hack, GraphQL, and React. Reusable, version-controlled assets with instantiation, overrides, and property reversion.
• Built Runtime Inspector, a real-time debugging and profiling tool that removed full Unity reloads and saved developers roughly 2 minutes per day.
• Migrated ~30% of the Horizon scripting API from the legacy Codeblocks engine to a new TypeScript-based scripting system.
• Ported ~50% of Horizon's asset-library game components from Unity C# to a new C++ standalone engine for better performance and cross-platform support.

Graduate Research Assistant

Arizona State University · Tempe, AZ

May 2021 to Dec 2021

Autonomous-vehicle falsification research plus GPU benchmarking of decision-tree inference.

• Integrated the SVL Simulator with S-TaLiRo (a MATLAB toolbox for falsifying cyber-physical systems) via a Python bridge that drove simulations until falsification. Modified SVL's C# source to support custom scenarios.
• Built a CUDA C++ GPU algorithm for decision-tree inference that was at least 2x faster than our optimized CPU baseline. Also explored FIL (cuML) for forest inference, tree re-organization, and compiling decision trees into tensor computations.

Undergraduate Research Assistant

BITS Pilani · Pilani, India

Aug 2019 to May 2020

GPU graphics and VR-based biomechanics research during undergrad.

• Parallelized Delaunay triangulation on GPU using CUDA C++ to generate meshes from point sets (Jan to May 2020).
• Tracked neck biomechanics with an Oculus Rift VR headset and mapped them to a real human skull. Computed each vertebra's position via inverse kinematics in OpenSim + Unity, then plotted position over time to surface defects (Aug to Dec 2019).
