## Work Experience
### Senior Software Engineer @ Dynamo AI
Jan 2024 – Present | San Francisco, California, United States
Own and lead engineering for DynamoGuard, the company’s primary real-time moderation product, ensuring reliability, delivering features, and driving cross-team coordination
- Built end-to-end pipeline for online model training and deployment, enabling customers to train and serve guardrail models self-serve and scaling the platform to more customers
- Led engineering initiatives to scale and harden systems, consolidating deployment images (7 → 3) to reduce complexity and spearheading a MongoDB → Postgres migration to address scalability bottlenecks
- Drove GPU slicing for model inference, cutting inference cost 10× for low/medium-throughput workloads through PoC benchmarking and deployment configuration optimization across SaaS and PaaS

### Graduate Researcher @ MIT Computer Science and Artificial Intelligence Laboratory (CSAIL)
Jan 2024 – Jan 2025 | Cambridge, Massachusetts, United States
Thesis: "Characterizing and Optimizing Networking Stack in Databases" advised by Michael Stonebraker
- Profiled VoltDB networking stack using perf, identifying server-side processing as a major bottleneck (~15% of query latency), exceeding execution time on transactional workloads
-Engineered kernel-bypass networking layer using DPDK and F-Stack via Java Native Interface (JNI), replacing the kernel TCP/IP stack and reducing server network overhead by up to 80%
- Improved database performance, achieving 44% higher throughput and 28% lower latency on Retwis, and 2× throughput on TPC-C at low concurrency.

### Teaching Assistant- Intro to Machine Learning @ Massachusetts Institute of Technology
Jan 2022 – Jan 2023 | Cambridge, Massachusetts, United States
Assisting students in understanding course materials. This involves helping them think through labs presenting applications of machine learning concepts and holding office hours to help with concepts and homework.

### Software Engineer Intern @ DynamoFL
Jan 2023 – Jan 2023 | Cambridge, Massachusetts, United States
- Developed the backend for a new product offering in NestJS and MongoDB to let clients evaluate private data leakage in their large language models (LLMs)
- Designed the privacy evaluation pipeline to reduce the cost of inference by using AWS Sagemaker
- Added support for privacy evaluation on custom trained GPT models from OpenAI

### Software Engineer Intern @ Balbix
Jan 2022 – Jan 2022 | San Jose, California, United States
- Built an automation tool to enable customers to create Jira tickets of security vulnerabilities directly from the Balbix dashboard with single click- down from more than 10 clicks (around 3 minutes)
- Implemented an ingestion pipeline for customer's security data from 3rd party source into central PostgreSQL database asynchronously via an Apache Kafka-based system

### Undergraduate Researcher- Document Processing with AI/OCR @ MIT Computer Science and Artificial Intelligence Laboratory (CSAIL)
Jan 2021 – Jan 2022 | Cambridge, Massachusetts, United States
- Enhanced a machine learning framework to understand and extract information from real-life noisy business invoices with high accuracy
- Built an end-to-end web interface to interact with the document processing algorithms

### Undergraduate Researcher- Differential Privacy and Web Development @ MIT Computer Science and Artificial Intelligence Laboratory (CSAIL)
Jan 2020 – Jan 2020 | Cambridge, Massachusetts, United States
- Developing Differentially Private versions of Machine Learning and optimization APIs in Pyspark and PyTorch with support for Federated Learning using PySyft
- Developed a secure backend architecture for a web interface to interactively try out basic Differential Privacy and Federated Learning in Flask and deployed in AWS

### Undergraduate Researcher- Data Analysis and Web Development @ Massachusetts Institute of Technology
Jan 2020 – Jan 2020 | Cambridge, Massachusetts, United States
- Worked on data pre-processing and engineering to analyze Call Data Records (CDR) of Sierra Leone to provide insights on mobility pattern to help in forming policies around COVID-19
- Developed an interactive user interface in Flask, PostgreSQL, Isotope to engage the visitors in Venice Architecture Biennale 2020 (canceled due to COVID-19) to explore open collectives
- Developed, and deployed in AWS, the backend and APIs for Visualize NYC 2021 web interface (www.visualizenyc.net) in Flask and MongoDB

### Frontend Web Developer @ MIT Computer Science and Artificial Intelligence Laboratory (CSAIL)
Jan 2019 – Jan 2019 | Cambridge, Massachusetts
Developed an interactive web interface to efficiently and effectively implement differentially private machine learning algorithms using HTML, CSS, Javascript, and Flask.

### Founder @ HamroLagi
Jan 2017 – Jan 2019 | Kathmandu
Initiated HamroLagi as a platform for sharing information and experiences about educational events for high school students.

### Graphics Designer and Web Designer @ OYA Inc.
