Venkata Satya Sai

I’m a Computer Science undergraduate passionate about backend engineering, distributed systems, and scalable software development. I’ve built cloud-native applications using the MERN stack, with a strong foundation in Data Structures and Algorithms and a focus on performance, security, and developer experience.

As a SWE Co-Op Intern, I developed and enhanced a production-ready Online Judge platform supporting coding problems, submissions, discussions, leaderboards, and AI-powered learning features. I designed and implemented 30+ secure REST APIs, improved backend response latency from 400 ms to 200 ms using caching and frontend local storage optimization, and built a secure Docker-based sandbox that blocks 10+ categories of malicious code execution attempts.

I’m also hands-on with authentication and infrastructure cost control—implementing JWT authentication, RBAC, HttpOnly cookies, and rate limiting—while deploying containerized backend services using Docker on AWS EC2. On the AI side, I integrated LLM-driven modules like an AI Study Planner and Mock Online Assessment to generate personalized learning roadmaps based on user goals and performance.
