I'm a final-year B.Tech Computer Science student and full-stack developer focused on building reliable, scalable web platforms and practical AI-powered applications. I built Skillnox, an online assessment and coding contest platform that recorded zero failed requests across 146,045 requests during a 5,000-virtual-user k6 stress test. Through iterative performance optimization, I reduced P99 latency from a 60-second timeout to 17 ms. I also developed Skillnox AI, a multi-round interview simulator powered by a locally hosted Qwen model using FastAPI and Ollama, and KITAGhire.in, a training and placement portal supporting college placement workflows for 3,000+ users. My technical interests include backend engineering, full-stack development, system design, performance optimization, authentication and security, and AI/LLM integration. I work with React, Next.js, Node.js, Express, Python, FastAPI, PostgreSQL, and related technologies. I won first place at the Codegnan Elevate X Hackathon with Global Smile and third place at the KITS Akshar CSE Department Hackathon with StudentConnect. I also served as a Google Student Ambassador, conducting technical workshops and growing a campus developer community. I'm interested in Software Development Engineer, backend, full-stack, and applied AI opportunities, and I'm open to relocating across India.

Skillnox — Online Assessment & Coding Contest Platform
Built and deployed a college-scale online assessment and coding contest platform. Validated the system with a 5,000-virtual-user k6 stress test that recorded 146,045 requests with zero failed requests. Optimized production bottlenecks, reducing P99 latency from a 60-second timeout to 17 ms. Implemented anti-cheating protections and Redis-backed session management across an eight-worker PM2 cluster.
Skillnox AI — AI Interview Simulation Platform
Developed an AI-powered interview simulator with aptitude, technical, and HR rounds. Integrated a locally hosted Qwen 2.5 3B model through Ollama and a Python FastAPI microservice. Built a concurrency-controlled evaluation queue, configurable pass/fail logic, a PostgreSQL-backed question bank with 1,000+ company-specific questions, voice-to-text answer capture, and webcam-based engagement signals.
KITAGhire.in — Training & Placement Portal
Developed a centralized college training and placement portal serving 3,000+ students, administrators, and recruiters. Automated more than 90% of targeted placement workflows and reduced reporting time by approximately 80%. Built a TPO dashboard with placement analytics, student performance tracking, attendance monitoring, and Excel/PDF reporting. Implemented role-based access control and optimized database queries to support 300+ concurrent users during placement drives.
