Varsha Sinha

I’m a Software Engineer specializing in backend and full-stack development, with a strong focus on secure authentication, reliable APIs, and clean documentation. I like turning requirements into production-ready systems that are easy to test, maintain, and extend.

In my Software Development Engineer Intern role, I developed RESTful APIs with Spring Boot for inventory and order management, improving data retrieval efficiency by 15%. I also built and optimized backend services for an e-commerce electric store platform handling 1,000+ records with 99% uptime, and added Swagger/OpenAPI documentation to reduce cross-team integration errors.

My projects reflect my end-to-end approach: I built a WebRTC-based video calling application supporting 10–15 concurrent users with sub-300ms latency, including secure authentication and a scalable MongoDB backend. I also created a GraphQL-powered AI-based expense tracker with protected access using Passport.js and bcrypt, plus responsive analytics using Tailwind CSS and Chart.js.

I’ve continued to explore ML-enabled features through an IPL win predictor achieving 85% accuracy and deploying real-time predictions with Streamlit. Beyond projects, I’ve ranked top 3 on institute-level competitive programming leaderboards on GeeksforGeeks, solved 500+ DSA problems, contributed to 10+ open-source projects via GSSoC, and earned certifications in cyber security tools and Generative AI.
