- Working under Prof. Christopher Batty in the Computational Motion Group on optimizing and parallelizing a mesh-based surface tracker using Intel TBB

- Worked in the Geometric Computing Lab on extending the X-shell deployable structure to have deformable rotational joints that store energy based on the Discrete Elastic Rods framework- Experimented with multiple joint models and eventually derived new energy and gradient, validated with the method of finite differences, for the model to simulate.

- Worked on geometry modelling features for Houdini 20 under Derrick Moser and Justin Bisceglio- Accelerated the TriDivide mesh subdivision tool, an algorithm based on the root-3 subdivision method, via parallel programming and other optimizations, achieving a 10x speedup- Investigated the paper "Reliable Feature-Line Driven Quad-Remeshing" and.

- Built a tool in Java for benchmarking the Bloomberg Query Language (BQL) analytics engine using the Java Microbenchmark Harness- Created a Python script that generates realistic, custom BQL data for creating benchmark cases- Automated benchmarking of various functions, column, and row size combinations on production machines and then used linear.

- Worked under Prof. Meng Xu to design and create a symbolic executor, a tool that explores possible paths of a program to find vulnerabilities, for a smart contract programming language using Rust and the Z3 Theorem Prover

- Led data engineers and analysts in designing data quality SLAs and Redshift schema structure to remedy data issues affecting hundreds of reports across 10+ teams- Created Kafka consumer microservice in Go to measure data quality metrics on tables in Redshift; sends data quality results and alerts to Datadog and Atlan- Integrated A/B testing vendors in Go.

Ontario, Canada

- Researched statistical methods for analyzing agent performance to create a recommendation system and a proof of concept with Elastic MapReduce, Spark, SciPy- Created coaching and learning sections of new home page of Genesys Cloud, used by over 30,000 customer service agents, with Vue.js, TypeScript, Jest- Reduced complexity of API endpoints by inferring.

Ontario, Canada

- Designed and created web pages for handling business data using AngularJS along with 6 new REST API endpoints in Node.js, Express.js- Created a Logstash pipeline for sending parsed error logs to an Elasticsearch cluster that is queried daily by a Jenkins job to alert developers- Refactored a Jenkins job to run a security scan of NPM packages on every.

- Resolved various requests and complaints using strong customer service and interpersonal skills- Served breakfast and restocked food for large groups of customers quickly while working under pressure- Used hotel software to manage guest information and coordinate with housekeepers
