Senior Software Engineer and MIT grad working infrastructure for running large-scale ML jobs at Meta. I specialize in Systems / Infrastructure, Artificial Intelligence, and 3D graphics.

## Work Experience
### Senior Software Engineer @ Meta
Jan 2023 – Present | New York, United States
Control Labs ML Launcher: Developed a custom ML launcher for the Neural Interfaces org, to configure, train, deploy, and interactively experiment with AI models across several teams. This consolidated the experience of several workflows with up to 10x faster startup times.

TorchX Universal PyTorch Job Manager: Consolidated multiple legacy ML model training workflows into common infra powered by TorchX. I led this migration and also landed multiple improvements, including faster runtime performance, logging capabilities, and better data validation. My system is used by hundreds of Meta engineers in both Ads and Instagram ranking.

OverlayFS-powered Build Accelerator: Created a new build system with novel intelligent caching algorithm and virtual filesystem support cutting build times by over 60%, from minutes to seconds. I worked across 4+ teams to land this system, saving them 300+ engineer-hours per week.

Content Addressed Filesystem Merge: Developed a new package format for distributed jobs, cutting package upload time by 90%, from 2 minutes to 12 seconds, by representing packages as collections of network pointers.

Mentoring & Tech Leadership: Provided technical mentorship to five engineers and two interns on projects in remote debugging, dependency management, AI training reproducibility, and lazy preprocessing optimizations. These projects saved 40+ engineer-hours per day and cut build breakage frequency from once per month to zero.

### Software Engineer @ Meta
Jan 2022 – Jan 2023 | New York, United States
AIEnv Dynamic Loading Framework: Developed a build cache and dependency manager that modified Python’s import system to cut build times from 20 minutes to 90 seconds for 100+ ML engineers across Instagram, Ads, and Reality Labs while simultaneously improving release health.

F6 Pipeline Scheduler - Container Management: Built containerization support for F6, Instagram’s ML pipeline scheduler. This allowed 60 ML engineers to run workflows with varied hardware (e.g. multi-CPU, multi-GPU).

### Junior Software Engineer @ Meta
Jan 2021 – Jan 2022 | New York, New York, United States
ML Checkpoint Throttling: Prevented network overloads and improved training time for 50+ engineers by implementing intelligent checkpoint scaling and throttling.

### Software Engineer Intern @ Meta
Jan 2020 – Jan 2020 | Menlo Park, California, United States
Physical Mouse Tracking for selective VR Passthrough

### Software Engineer Intern @ NVIDIA
Jan 2019 – Jan 2019 | Santa Clara, California, United States
NVIDIA Drive IX Intern - Summer 2019

Jarvis multimodal assistant (C++, Java, Python, TensorRT, CUDA)
SIGGRAPH 2019 demo - realtime 3D pose estimation (C++, Python, CUDA, PyTorch)

### Software Engineer Intern @ NVIDIA
Jan 2018 – Jan 2018 | Santa Clara, California, United States
NVIDIA Intern - 3D Performance

Predictive GPU Power Scaling (C++, 3D graphics)

### Software Engineer Intern @ ISEE
Jan 2018 – Jan 2018 | Cambridge, Massachusetts, United States
Google Maps Self Driving Car Simulation in the Cloud (Unreal, C++, Python, ROS, AWS)

### Software Engineer Intern @ NASA Jet Propulsion Laboratory
Jan 2017 – Jan 2017 | Pasadena, California, United States
Supratactical - Curiosity Rover Mission Planning Collaborative Web App (React, Javascript, Node.js)
OnSight AR Mars Experience - Synchronous collaboration mode (C#, Unity, Photon, Blender)
