Hi, my name is

Junda Shen.

I build things for the future.

I'm a software engineer specializing in building and occasionally designing large-scale infrastructure with ultra-high-performance code. Currently, I work as an SDE in the EC2 VPC org at AWS.

About Me

Hello! I'm Junda, and I recently earned my Master's in Computer Science from the University of Illinois at Urbana-Champaign.

Fast-forward to today, and I've had the privilege of working at an enterprise software corporation and an EV manufacturer. My primary focus is on enhancing workflows and creating scalable solutions with C++, Python, and JavaScript.

I have extensive experience in database management using MySQL and MongoDB, and a keen interest in high-performance computing, particularly with CUDA for accelerating general-purpose computations. Additionally, I've been involved in projects that scale services using containers and Kubernetes.

Here are a few technologies I've been working with recently:

  • C/C++
  • Python
  • Java
  • CUDA
  • React
  • Node.js
  • MySQL
  • MongoDB
  • Elasticsearch
  • Kubernetes
