Projects
Email Notification Service (ERIN)
Node.js, AWS Lambda, DynamoDB, SendGrid
Developed a serverless email notification system for a referral platform using event-driven AWS Lambda processors. Refactored legacy email workflows into modular processors with SendGrid templates, dynamic content rendering, and multi-language support.
Scalable Robot–Target Interception Planner
C++
Designed a robot planning system to intercept a moving target on large weighted 2D costmaps while performing collision checking and trajectory alignment. Scaled planning to maps with ~4.2M cells and ~5.3K time steps while reducing memory usage by ~55% and planning time by ~60–70% relative to a baseline time-augmented A* approach.
Order Management System
Ruby on Rails, React
Developed a full-stack order management application with a Rails backend and React frontend supporting authentication, role-based authorization, and a relational database schema. Built RESTful APIs and optimized ActiveRecord queries with fastjsonapi serialization for efficient client–server data exchange.
High-DoF Robotic Arm Motion Planning
C++
Implemented sampling-based motion planning algorithms (RRT-Connect and PRM) to generate collision-free trajectories for a high-degree-of-freedom planar robotic arm. Benchmarked planning time, path cost, and success rate across randomized start–goal configurations under a <5 second planning constraint.
Dynamic Memory Allocator
C
Implemented a dynamic memory allocator supporting malloc, free, realloc, and calloc. Improved memory utilization by ~17% using segregated free lists and more efficient block management to reduce fragmentation.
MazeRunner (Procedural Maze Game)
Python
Built an interactive maze exploration game using an MVC-style architecture with cmu_112_graphics. Implemented procedural maze generation using DFS backtracking and Prim’s algorithm to create randomized maze layouts with different difficulty levels.
