Purushottam Choudhary

I’m a Computer Science undergraduate (2026) with strong foundations in Data Structures, Algorithms, and scalable backend engineering. I’m passionate about building reliable, testable, production-grade systems with a clear focus on scalability and performance.

In my Domain Intelligence System, I built a FastAPI backend handling 500+ queries/day with 150ms avg latency. I also implemented FAISS-based search over 10K+ documents and achieved 0.91 ROC-AUC on churn prediction using Logistic Regression, delivering real-time predictions through well-optimized REST APIs.

I’ve also developed an end-to-end Image & Text Based Plagiarism Detection System with an OCR pipeline reaching high accuracy on noisy inputs, plus embedding-based semantic similarity for detection. During my Web Development internship at SH Solutions, I developed and integrated REST APIs, collaborated via Git workflows, and worked on backend debugging and feature development—alongside solving 500+ DSA problems on LeetCode.
