I’m an AI Engineering Intern at PowersMy.biz, where I build production AI assessment systems for JEE and NEET coaching institutes. I focus on reliability under real load, so my work goes beyond models to scalable services and smooth user experiences.

In my current role, I built a production AI assessment platform supporting 1,000+ concurrent exam-takers using FastAPI, LangGraph, React, Flutter, MongoDB, Redis, and GCP. I optimized high-concurrency exam APIs with Redis caching, atomic MongoDB operations, and off-thread bcrypt processing to sustain peak load during exam-day traffic spikes.

I also engineered a multimodal AI evaluation pipeline that grades handwritten subjective answers across 8 question formats and identifies learning gaps. To keep grading responsive, I designed an asynchronous grading queue across 2 services so objective scores return instantly while deeper evaluation runs in the background.

I collaborate across multiple production repositories (backend, web, mobile, and AI-agent) by using Git/GitHub workflows—raising pull requests, reviewing code, resolving merge conflicts, and writing test cases. Alongside this, I solve 350+ algorithmic problems and build projects like a DSA Visualizer and a competitive programming profile aggregator to translate ideas into working software.
