About Me

Who I Am

I'm a Backend-heavy Full-Stack Engineer and Computer Science student at GWCET, Nagpur — obsessed with building systems that work at massive scale.

I specialize in distributed system design, high-concurrency Node.js architectures, AI pipeline engineering, and database optimization. My flagship project HeartEcho scaled from zero to 550,000+ users using a custom Priority Queue + Redis Emotional Cache system I designed from scratch.

O(1)

Room lookup complexity

Built a CLI-based Room Allotment & Booking System in C++ as the internship capstone — supporting room booking, host assignment, time-slot scheduling, chair-count configuration, and real-time room status queries across customizable room parameters.
Implemented the scheduling engine using a priority queue to handle overlapping booking requests and a hash map for O(1) room status lookups; resolves conflicts across 6 configurable parameters without collision.
